TROUBLESHOOTING CHART
INSTALLATION
If the electric generating set is to operate properly, it must be correctly installed. This manual gives some of the more important aspects of installation. For more details, a Technical Bulletin (T-012) is available from Onan.
Ventilation is the most important factor to be considered. The unit must have enough cooling air to operate safely and efficiently. The heated air must be disposed of to keep the engine from overheating and losing power.

AUTOMOTIVE HANGERS
For the CCK set running at 1800 rpm, the amount of air discharged is 750cfm. The minimum free air inlet with no filter or restriction is 140 sq. in .
Onan Vacu-Flo cooled units are specifically designed for mounting in small compartments (where proper cooling is difficult) and are equipped to provide sufficient cooling air and adequate disposition of heated air. With this type of cooling, a centrifugal fan in a scroll housing pulls cooling air into the compartment

:
and over the cooling fins and surfaces of the engine. Heated air is expelled through a single discharge and away from the unit and installation area.
LOCATION The compartment itself should be of vapor tight design and completely independent of living quarters. The interior lining should be fireproof. A sheet metal covered compartment may be readily sealed and lends itself easily to treatment. The set may have to be removed for service, so make the door large enough to facilitate removal of the unit.
The compartment location is determined by physical size, access opening and most important, best mounting sup port. Allow 2 ,, clearance on all sizes of the unit for rocking on mounts.
POSITIONING The following should be considered for accessibility when mounting the unit in a compartment. (Position so operating instructions and nameplate are visible and/or install an accessible nameplate, data decal or sticker.)
1. Make air discharge duct as short as possible. Position so exhaust heated air is not drawn into cool air inlet.
2. Air cleaner should be easy to remove and service. 3. Battery or batteries must be accessible for service. 4. Oil fill tube cap should be easy to reach. S. The control box switch should be visible. 6. Provide space for muffler. 7. Oil drain should be readily accessible. 8. Cylinder head should be readily accessible for
service. 9. Rope start sheave should be accessible.
MOUNTING The best method of mounting is to attach the set to a mounting platform using Onan vibration isolators. See Figure 2. The vibration isolators must be properly installed to minimize vibration. The Onan mounts are a "fail-safe" type with mounting bolts that prevent the unit from breaking loose if the mounts are damaged.
The mounting base should be fastened directly to the supporting frame. Channel, box or angle iron can be used for a mounting base frame. This will provide the greatest support, plus a base sealed against air, dirt and sound. Do not use sheet metal or thin plate without a supporting frame.
~ Plywood is vulnerable ~ elements, will tend to soaked, and is not fireproof.
to climatic become oil
The supporting base or platform must be strong enough to withstand the shock from sharp turns, bumps, holes, etc. which accompany mobile applications. Brace the mounting platform to eliminate any chance of the platform bowing or bending.

FIGURE 2. ONAN VIBRATION ISOLATORS
FUEL SUPPLY (GASOLINE) Install a separate fuel tank for the unit. If the set has to be connected to the vehicle supply tank, do not tee off the vehicle supply line. The generating set must have a separate fue 1 line because the more powerful vehicle fuel pump will starve the generating unit for gasoline.
FUEL LINES Use annealed copper or seamless steel tubing and flared connections. Run fuel lines, at the top level of the tank to a point as close to the engine as possible, to reduce the danger of fuel siphoning out of the tank if the line should break. Install lines so they are accessible at all times and protected from mechanical injury. Use nonferrous metal straps, without sharp edges, to secure the fuel lines.
EXHAUST SYSTEM Observe the following when installing the set's exhaust system:
1. Construct exhaust system to prevent damage from leakage and vibration. Use automotive type hangers and connections under the vehicle.
2. Use an insulating thimble where exhaust piping passes through a partition or floor of flammable material. Exhaust lines may be asbestos wrapped to reduce heat radiation within the compartment.
3. Terminate the exhaust outlet aft of the set compartment and extend to perimeter of vehicle so DEADLY exhaust fumes will not enter vehicle under ordinary conditions of driving or parking.
WARNING • Do not install the exhaust outlet ._ _____ _.! closer than three feet from the gasoline filler spout. Do not pipe exhaust into Vacu-F lo scroll.
When installing mufflers, other than those supplied with the unit or if the exhaust system is excessively complicated, the exhaust back pressure should be checked. Exhaust back pressure at rated load, measured at the exhaust manifold, should not exceed 2 in. Hg. (Mercury column). Where a tapped hole is not provided, the manifold and/or a pipe coupling may be drilled and tapped. After measurement is made, plug the hole with an ordinary pipe plug.
WARNING ~ Do not use discharged Vacu-Flo air -------•- for heating since it may contain carbon monoxide or other poisonous gases.
BATTERY CONNECTION Connect the positive (+) battery cable to the start solenoid. Connect the negative (-) cable to the generator through-bolt. Refer to Figure 3.
-[~Do. not d~sconnect th_e st~rting ~at--~ terzes while the engine zs running.
The resulting overvoltage will damage the electric choke and other control components. Do not reverse battery connections; doing so may damage the electrical system.
In mobile applications where the generator is normally operated in ambient temperatures above O °F and the battery is kept charged by frequent running of the unit, a single 12 volt battery of 74 amp/hr capacity minimum is sufficient.
LOAD WIRE CONNECTIONS The set nameplate shows the electrical output rating of the set in watts, volts and cycles. The wiring diagram shows the electrical circuits and connections necessary for the available output voltage. Also see Figure 4.
Meet all applicable code requirements. A qualified serviceman or electrician should make the installation and the installation should be inspected and approved. The AC output box has provisions to accomodate load wires. Use flexible conduit and stranded load wires near the set to absorb vibration. Use sufficiently large insulated wires. Strip the insulation from the wire ends as necessary for clean connections. Connect each load wire to the proper generator output lead inside the AC output box. Insulate bare ends of ungrounded wires. Install a fused main switch (or circuit breaker) between the generating set and the load.
Ground (Generator to Vehicle): A solderless terminal is provided between AC output box and control on top side of unit. Connect a ground between this terminal and clean, bare metal on vehicle frame. See Figure 3.
Output Lead Markings: Generator leads are marked, Ml, M2, M3 and M4. These identifying marks also appear on the wiring diagram.

Voltage Selection on Reconnectible Single Phase Generators: These units are reconnectible for use as 120/240volt, 3wire; 120volt, 2wire; or a 240volt, 2 wire power source (see Figure 4). Use the connection for two wire service when one load exceeds 1/2 the rated capacity. Balance the load when connecting for three-wire service.
Balancing the Load: Current for any one output lead must not exceed nameplate rating. Serious overloading can damage the generator windings. When two or more single phase circuits are available, divide the load equally between them.
Load Connections: Refer to the figure which illustrates the load connection for the output shown on the nameplate.
CONTROL BOARD REMOTE WIRING (BEGIN SPEC R) The printed circuit board (located under start-stop control) i:s the "heart" of the generating set's control system. Terminals 1 through 9, on the left side of printed circuit board, (Figure 6) connect to engine components such as:
• Ignition Points • Ignition Coil and Fuel Pump • Start Solenoid • LOP (Low Oil Pressure) • HET (High Engine Temperature) • Charging Resistors
Terminals 10 through 18, located on right side of printed circuit board, are for connection to a Remote Control Station. These include the following:
• Start-Stop Switch • Charging Ammeter • Running Time Meter
11
• Generator "On" Light • LOP (Low Oil Pressure) Alarm • HET (High Engine Temperature) Alarm
Remote Start-Stop Switch: To connect a remote startstop switch, use a double-throw, double-pole switch (Onan No. 308A329) and connect as shown in Figures 5 and 6. Use No. 18 wires for connection for distances up to 250 feet.

OPERATION
BEFORE STARTING Crankcase Oi I: Be sure the crankcase has been filled with oil to the "FULL" mark on. the oil level indicator. Refer to the Maintenance Section for the recommended oil changes and complete lubricating oil recommendations.
Recommended Fuel: Use clean, fresh, regular grade, automotive gasoline. Do not use highly leaded premium types.
For new engines, the most satisfactory results are obtained by using nonleaded gasoline. For older engines that have previously used leaded gasoline, heads must be taken off and all lead deposits removed from engine before switching to nonleaded gasoline.
~ If ]~ad deposits _are _not removed from ~ engme before swztchmg from leaded to non leaded gasoline, preignition could occur causing severe damage to the engine.
ELECTRIC STARTING Push the Start-Stop switch to its "START" position. Release the switch as soon as the engine starts.
If the engine fails to start at first try, inhibitor oil used at the factory may have fouled the spark plugs. Remove the plugs, clean in a suitable solvent, dry thoroughly and install. Heavy exhaust smoke when the engine is first started is normal and is caused by the inhibitor oil.
OPTIONAL MANUAL STARTING (Begin Spec R) If the battery charge condition is too low to crank the engine, some engines equipped with a rope sheave, can be started manually. Move "Rope Start" button to "Hold" position. Pull the rope with a fast, steady pull to crank the engine. Do not jerk. After starting, release "Hold" switch .
NOTE: Units not equipped with rope sheave cannot be started manually.
MANUAL ST ART ING {Through Spec P) Set the control box switch to its manual start position. Pull the rope with fast, steady pull to crank the engine. Do not jerk. ·ter starting, return the control b.ox switch to the electric start position to avoid discharging the battery.
APPLYING LOAD If practical, allow set to warm up before connecting a heavy load. Continuous generator over10 ding may
13
ca·use high operating temperatures that can damage the windings. Keep the load within nameplate rating.
STOPPING 1. Push Start-Stop switch to "STOP" position. 2. Release switch when unit stops.
BREAK-IN PROCEDURE Controlled break-in with the proper oil and a conscientiously applied maintenance program will help to assure satisfactory service from your Onan electric generating set.
When operating engine for the first time, use the following sequence using SE or SE/ CC oil (former designation was MS or MS/DG):
1. One half hour at 1/2 load. 2. One half hour at 3/4 load. 3. Full load. 4. Change crankcase oil after the first SO hours of
operation.
BATTERY CHARGING (Begin Spec R) The battery charge rate is automatically controlled by a solid-state voltage regulator. The high charge rate was set at the factory for average operating conditions.
INFREQUENT SERVICE If the set is used infrequently, extended shutdown periods can result in difficult starting. Run unit at least 30 minutes every week to eliminate hard starting.
HIGH TEMPERATURES 1. See that nothing obstructs air flow to and from
the set. 2. Keep CDoling fins clean. Air housing should be
properly installed and undamaged. 3. Keep ignition timing properly adjusted.
LOW TEMPERATURES 1. Use correct SAE No. oil for temperature conditions.
Change oil only when engine is warm. If an unexpected temperature drop causes an emergency, move the vehicle to a warm location.
2. Use fresh gasoline. Protect against moisture condensation. Below 0 ° F adjust carburetor main jet for a slightly richer fuel mixture.
3. Keep ignition system clean, properly adjusted and batteries in a: well charged condition.
4. Partially restrict cool air flow, but use care to avoid overheating.
OUT-OF-SERVICE PROTECTION Protect a set that will be out-of-service for more than 30 days as follows:
1. Run the set until thoroughly warm. 2. Turn off fuel supply and run until engine stops. 3. Drain oil from oil base while still warm. Refill
and attach a warning tag stating oil viscosity used.
4. Remove each spark plug. Pour 1 oz. (two tablespoons) of rust inhibitor (or SAE #50 oil) into each cylinder. Crank engine slowly (by hand) several times. Install spark plugs.
S. Service air cleaner. 6. Clean governor linkage and protect by wrapping
with a clean cloth. 7. Plug exhaust outlet to prevent entrance of moisture,
dirt, bugs, etc. 8. Wipe generator brushes, slip rings, etc. Do not
apply lubricant or preservative. 9. Wipe entire unit. Coat rustable parts with a light
film of grease or oil. 1 O. If battery is used, disconnect and follow standard
battery storage procedure.
DUST AND DI RT 1. Keep set clean. Keep cooling surfaces clean. 2. Service air cleaner as frequently as necessary. 3. Change crankcase oil every SO operating hours
or sooner. 4. Keep oil and gasoline in dust-tight containers. S. Keep governor linkage clean. 6. Clean generator brushes, slip rings and commutator.
Do not remove normal (dark brown) film. Do not polish.
HIGH ALTITUDE For operation at altitudes of 2500 feet above sea level, close carburetor main jet adjustment slightly to maintain proper air-to-fuel ratio (refer to the Adjustment Section). Maximum power will be reduced approximately 4% for each 1000 feet above sea level, after the first 1000 feet.

ADJUSTMENTS
BREAKER POINTS , 1. Remove the two screws and the cover on the
,
:
breaker box. 2. Remove the two spark plugs so engine can be
easily rotated by hand. 3. Turn flywheel in a clockwise direction approxi
mately 1/ 4 turn after top center (TC). 4. To adjust gap refer to Figure 7. Loosen screws
(A) and turn cam (B) until point gap measures .020 " with a flat thickness gauge. Retighten screws (A) and recheck gap.
5. If points are slightly burned, dress smooth with a file or fine stone. If points appear to be burned and pitted, replace them with a new set.
6. Replace spark plugs and breaker box cover.
IGNITION TIMING Both spark plugs on the CCK fire simultaneously, thus the need for a distributor is eliminated. Spark advance is set at 19 ° BTC (before top center) and should be maintained for best engine performance. Always check timing after replacing ignition points or if noticing poor engine performance. Proceed as follows :
Timing Procedure - Engine Running: 1. To accurately check the ignition timing, use a
timing light when e ngine is running. Connect the timing light according to its manufacturer's instructions. Either spark plug can be used as they fire simultaneously.
2. Remove the plug from the timing hole. 3. Start the engine and check the timing. The mark
~on the flywheel should line up with the 19° BTC mark on the cover.
4. If timing needs adjustment, loosen the mounting screws on breaker box and move left to advance or right to retard the timing.
S. Start engine to be sure mark on flywheel lines up with 19 ° mark on cover.
6. Tighten all screws, replace timing plug.
Timing Procedure - Engine Not Running: 1. Connect a continuity test lamp set across the
ignition breaker points. Touch one test prod to the breaker box terminal to which the coil lead is connected and touch the other test prod to a good ground on the engine.
2. Turn crankshaft against rotation (counterclockwise) until the points close. Then slowly turn the crankshaft with rotation (clockwise).
3. The lamp should go out just as the points break which is the time at which ignition occurs (19 ° BTC).

CARBURETOR, GASOLINE The carburetor has an adjustable idling jet and an adjustable main jet. If the engine runs unevenly at half or full load due to faulty carburetion, the main adjusting needle requires adjustment. The idle adjustment needle normally requires little attention other than a periodic cleaning . A hunting condition (alternate increase and decrease in engine speed) at no load can sometimes be adjusted by an idle jet adjust)llent. Make all adjustments with the engine at normal operating temperature.
To adjust the main jet, connect a full or nearly full load to the engine. Turn the main adjusting needle out about two full turns. Then turn it in slowly until the engine begins to lose power and speed. Then turn it out slowly until the engine runs smoothly at full power and speed. If the engine develops a hunting condition try correcting by opening the main adjusting needle a little more. Do not open more than 1/ 2 turn beyond the maximum point of power. If this does not correct the condition, adjust the sensitivity of the governor.

Make the idle jet adjustment with no load connected to the engine. Turn the needle in until the engine loses considerable speed. Then turn it out until the engine runs smoothly.
SISSON CHOKE This choke should not require any seasonal readjustment. If adjustment becomes necessary , pull choke lever up and insert a 1/ 16" diameter rod through shaft hole (opposite end from lever) and engage rod in notch of mounting flange, to lock shaft in place.
Loosen the choke lever clamp screw. With air inlet removed, adjust choke lever so carburetor choke plate is completely closed, or not more than 5 / 16 " open. Tighten choke lever clamp screw and remove locking rod from shaft.

FIGURE 10. SISSON CHOKE
THERMO-MAGNETIC CHOKE This choke uses a strip heating element and a heat sensitive bimetal spring to control the choke plate position. In addition to this, a solenoid is actuated during engine cranking, closing the choke all or part way, depending on ambient temperature. The bi metal is factory set to position the choke to the proper opening under any ambient condition.
If adjustment of the bimetal is needed, it must be made at ambient temperature. Do not attempt adjustments until the engine has been shut down for at least one hour. Loosen the screw which secures the choke body assembly (see Figure 11). Rotating the choke body clockwise richens and counterclockwise leans the choking effect. For ambient temperatures below 60 ° F the choke should be opened 1/ 8 " with the solenoid not engaged. Tighten the screw that secures the choke body.

GOVERNOR AND BOOSTER The governor and booster control the speed of the engine. A speed adjustment includes adjusting both devices (Figure 13).

GOVERNOR Before making final governor adjustments, run the unit about 15 minutes under light load to reach normal operating temperature. (If governor is completely out of adjustment, make a preliminary adjustment at no load to first attain a safe voltage operating range).
Engine speed determines the output voltage and current frequency of the generator. By increasing the engine speed, generator voltage and frequency are increased, and by decreasing the engine speed, generator voltage and frequency are decreased. An accurate voltmeter or frequency meter (preferably both) should be connected to the generator output in order to correctly adjust the governor. A small speed drop not noticeable without instruments will result in an objectionable voltage drop. The engine speed can be checked with a tachometer.
A binding in the bearings of the governor shaft, in the ball joint, or in the carburetor throttle assembly will cause erratic governor action or alternate increase and decrease in speed (hunting). A lean carburetor adjustment may also cause hunting. Springs of all kinds have a tendency to lose their calibrated tension through fatigue after long usage. If all governor and carburetor adjustments are properly made, and the governor action is still erratic, replacing the spring with a new one and resetting the adjustments will usually correct the trouble.
1. Adjust the carburetor main jet for the best fuel mixture while operating the set with a full rated load connected.
2. Adjust the carburetor idle needle with no load connected.
3. Adjust the length of the governor linkage and check linkage and throttle shaft for binding or excessive looseness.
4. Adjust the governor spring tension for rated speed at no load operation with booster disconnected (or held inoperative).
S. Adjust the governor sensitivity. 6. Recheck the speed adjustment. 7. Set the carburetor throttle stop screw. 8. Set the vacuum speed booster.
LINKAGE The engine starts at wide open throttle. The length of the linkage connecting the governor arm to the throttle shaft and lever is adjusted by rotating the ball joint. Adjust this length so that with the engine stopped and tension on the governor spring, the stop on the carburetor throttle lever just contacts the underside of the carburetor bowl. This setting allows immediate control by the governor after starting. It also synchronizes travel of the governor arm and the throttle shaft.
SPEED ADJUSTMENT With the warmed-up unit operating at no load, and with the booster external spring disconnected (or
otherwise held inactive), adjust the tension ot the governor spring. Refer to Voltage Chart and the Speed Chart and select the column which corresponds to the nameplate of the unit in question. Turn the speed adj us ting nut to obtain a voltage and speed reading within the limits shown.

SENSITIVITY ADJUSTMENT Refer to the Governor Adjustment illustration, and to the Voltage and Speed Charts. Check the voltage and speed, first with no load connected and again with a full load. Adjust the sensitivity to give the closest regulation (least speed and voltage difference between no load and full load) without causing a hunting condition.
To increase sensitivity (closer regulation), shift the adjusting clip toward the governor shaft.
An adjustment for too much sen sit iv ity will cause alternate increase and decrease of engine speed (hunting).
To decrease sensitivity, shift the adjusting clip toward the outer end of the governor arm. Too little sensitivity will result in too much difference in speed between no load and full load conditions.
Any change in the sensitivity adjustment usually requires a compensating speed (spring tension) adjustment.
SPEED BOOSTER After satisfactory performance under various loads has been attained by governor adjustments without the booster, the booster can be connected. Connect the booster external spring to the bracket on the governor link (rod). With the unit operating at no load, slide the bracket on the governor link just to the position where there is no tension on the external spring (Figure 13).

. .
Apply a full rated electrical load to the generator. The output voltage should stabilize at nearly the same reading for full load as for no load operation. The speed may remain about the same or increase when the load is applied, resulting in a frequency 1 or 2 hertz higher than the no load frequency (1 hertz is equal to 30 rpm for a 4 pole generator). If the rise in frequency is more than 2 hertz, lessen the internal spring tension. If there is a drop in the frequency, increase the booster internal spring tension. To increase the tension, pull out on the spring bracket and move the pin to a different hole.
With the booster disconnected, a maximum drop of 3 hertz from no load to full load is normal. With the booster in operation, a maximum increase of 2 hertz from no load to full load is normal. A drop of 1 hertz at 1/4 load is permissible, giving an overall spread of 3 hertz maximum.
The effect of the booster is limited by the general condition of the engine. The booster cannot compensate for a loss in engine vacuum caused by leaky valves, worn piston rings, etc .

SERVICE AND MAINTENANCE
CRANKCASE OIL Fill to the "F" mark on the oil level dipstick. Use a good quality detergent oil that meets the API (American Petroleum Institute) service designations SE or SE/CC. Oil should be labeled as having passed the MS sequence tests (also known as the ASTM G-IV sequence tests) and the MIL-L-2104B tests. Use the proper SAE number of oil for the expected temperature conditions. Do not mix brands or grades. Extremely dusty or low temperature conditions require oil changes more often than normal. Oil capacity is 4 U.S. quarts.
CRANKCASE BREATHER Lift off rubber breather cap. Carefully pry valve from cap. Otherwise press hard with both thumbs on top of the cap and fingers below to release valve from rubber cap. Wash this fabric flapper type check valve in a suitable solvent. Dry and install. Position perforated disc toward engine.
AIR CLEANER Begin Spec R: Under normal operating conditions clean the air filter every SO hours. To clean, remove foam strip and element and tap element on a clean flat surface to dislodge the dirt particles. Do not use high pressure compressed air as damage may occur to paper pleats. Replace element every 500 hours. Replace more often in dusty conditions.
Thru Spec P: Clean screen and cup in a suitable solvent. Refer to level indicated on cup. Use the same type of oil as used in crankcase. Refer to Operator Maintenance Schedule for further recommendations.

GENERATOR MAINTENANCE The generator normally needs little care other than a periodic check of the brushes, commutator and collector rings. If a major repair job on the generator should become necessary, have the equipment checked by a competent electrician who is thoroughly familiar with the operation of electric generating equipment.
Brush Replacement (Begin Spec R): Install new brushes when the old ones are worn to the dimensions shown in Figure 21. Remove the end bell band to expose the brush holders. Remove the three screws holding each brush holder in place. Remove the old brushes and clean the holders so the new brushes can move easily in their holders. Install the new brushes in the same manner as the old ones. Always use the correct brush as listed in the Parts Catalog section. Never substitute a brush which may appear to be the same, for it may have different characteristics. New brushes are shaped to fit and seldom need sanding to seat properly. If some brush sparking occurs after replacing brushes, run the set under a light load until the brushes wear to a good seat.

Collector rings acquire a glossy brown finish in normal operation. Do not attempt to maintain a bright newly machined appearing surface. Ordinary cleaning with a dry, lint free cloth is usually sufficient. Very fine sandpaper (#00) may be used to remove slight roughness. Use only light pressure on the sandpaper, while the unit is operating. Do not use emery or carburundum paper or cloth. Clean out all carbon dust from the generator.
Brush Replacement (Thru Spec P): Install new commutator brushes when the old ones are worn to 5/8" in length. The collector ring brush may be used until. worn to 5/8" in length. It is not necessary to remove the brush rig to install new brushes. Remove the end cover to expose the brush rig. Brushes and leads are then easily accessible. New brushes are shaped to fit and seldom need sanding to seat properly. Always use the correct brush as listed in the parts list. Never substitute a brush which may appear to be the same, but may have different electrical characteristics. Be sure to tighten the brush lead terminal nuts. If some brush sparking occurs after replacing brushes, run the unit at a light load until the brushes wear to a go_od seat.
