Procedures
12Adjust Carburetor adjustment
⚠ Do not force needles against seats.
- Open both needles 1 to 1-1/2 turns off seats.
- Apply full load; turn main fuel screw in until speed drops, then out to normal.
- Remove load; turn idle screw out until speed drops, then in to normal.
Adjust Governor Linkage (Diesel) adjustment
- Loosen locknuts on governor linkage, remove link at one ball joint.
- Position governor arm and fuel control arm fully forward.
- Adjust linkage so both ball joints fit without moving arms.
- Tighten locknuts.
- Release fuel solenoid plunger.
Adjust Valve Clearance (Diesel) adjustment
Tools: feeler gauge, socket wrench
- Turn flywheel to compression stroke for cylinder to adjust.
- Turn flywheel clockwise additional 10 to 45 degrees.
- Loosen locknut to increase clearance, tighten to reduce.
- Use feeler gauge to set proper gap.
- Adjust in firing order 1-2-4-3.
Adjust Valve Tappet (Gasoline) adjustment
Tools: feeler gauge, wrench
- Remove valve covers.
- Crank engine until intake valve opens and closes.
- Continue 1/4 turn until timing marks align.
- Turn adjusting screw to obtain correct clearance.
- Use flat feeler gauge between valve and valve rotator.
Battery Charge Rate Adjustment adjustment
⚠ Avoid overcharging.
Tools: DC ammeter
- Set slide tap on resistor R4 to about 2 amperes charging rate.
- For frequent starts, increase charge rate slightly until battery stays charged.
- Stop engine when readjusting to avoid shorts.
Brush Rig Alignment adjustment
⚠ If a voltmeter is not available, use the same procedure but mark the point where arcing begins.
Tools: voltmeter
- With the generator end cover and band removed, connect a voltmeter across the DC terminals.
- Start the unit and apply full rated load.
- Loosen the brush rig mounting screws and rotate the rig to get the highest voltage.
- Rotate the rig in one direction until the voltmeter reading starts to decrease; mark this point.
- Repeat step 3 in the other direction.
- Half the distance between the two marked points is the neutral position.
Carburetor Final Adjustment (gasoline) adjustment
⚠ Valves may be damaged by turning them in too far.
Tools: Screwdriver
- Turn main fuel valve in until engine misses (lean), then out past smooth until uneven (rich); set to mid-point.
- Hold engine at idle and set low speed adjustment screw until a fast idle of 1200 rpm is obtained.
- Turn idle adjustment valve in (lean) and out (rich) until engine idles smoothly.
- Reset low speed adjustment screw so engine idles at 1200 rpm.
- Release throttle; engine should accelerate without hesitation, readjust main fuel valve if not.
Crankshaft Endplay Adjustment adjustment
Tools: torque wrench
- After rear bearing end plate is tightened, check crankshaft endplay.
- If there is too much endplay, remove rear bearing end plate and replace gasket with thinner gasket from gasket kit.
- If there is too little endplay, remove rear bearing end plate and replace gasket with thicker one.
- Reinstall end plate making sure thrust washer notches line up with lock pins.
- Torque and recheck endplay of crankshaft.
Cylinder Head Tightening adjustment
Tools: torque wrench
- Tighten cylinder head bolts in order designated per Figure 44.
- Torque to 5 foot-pounds (6.8 Nm).
- Torque to 10 foot-pounds (13.5 Nm).
- Continue in steps until all are torqued to 29 to 31 foot-pounds (39-42 Nm).
Cylinder Head Torque adjustment
Tools: torque wrench
- Tighten cylinder head in order designated per Figure 44.
- Torque to 5 foot-pounds (6.8 Nm), then 10 foot-pounds (13.5 Nm), etc. until all are torqued to 29 to 31 foot-pounds (39-42 Nm).
Flowing the Pump (PLB timing) adjustment
- Install pump with .006-inch (0.15 mm) shims between pump and pad.
- Loosen delivery valve holder to relieve pressure on spring.
- Rotate flywheel to about 15 degrees before port closing point.
- Operate transfer pump hand primer lever and rotate flywheel slowly clockwise until fuel stops coming out of pump outlet.
- Measure distance from port closing point to PC mark and add shims per table.
- Install pump.
Gasoline Carburetor Adjustment adjustment
⚠ Do not force needle valves against their seats; this can bend the needle.
Tools: Tachometer
- Warm up engine. With no load, turn idle fuel adjustment out until speed drops slightly below normal, then in until speed returns to normal.
- Apply a full load to engine.
- Loosen packing nut and turn main adjustment in until speed drops slightly below normal, then out until speed returns to normal.
- Tighten packing nut.
