NOTICE |
---|
Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
Note: The No. 1 piston must be set at the top center position (TC) in order to perform all of the timing procedures.
Note: The engine is seen from the flywheel end when the direction of the crankshaft rotation is given.
- Remove the electric starting motor.

- Install Tool (A) into the flywheel housing, as shown.
- To find the TC position for the No. 1 piston, perform the following procedure:
- Turn the flywheel clockwise or turn the flywheel in the opposite direction of the engine rotation for approximately 30 degrees. This removes all play from the timing gears.
Note: If you go past the bolt hole, repeat Step 3.a.
- Remove plugs (1) and (2) .

- Turn the flywheel counterclockwise until a 3/8-16 X 3 1/2 NC bolt (4) can be installed in the flywheel through the hole in the flywheel housing. The No. 1 and No. 6 pistons are now at the TC position. Plug (2) was removed for viewing through inspection hole (3) .

- In order to check the position of the inlet and exhaust valves, remove the valve mechanism cover. Refer to Disassembly and Assembly, "Valve Mechanism Cover - Remove and Install".
Note: The No. 1 piston is on the compression stroke when the valves of the No. 1 cylinder are closed. The rocker arms for the inlet valves and for the exhaust valves must have slight side-to-side movement.
- Turn the flywheel clockwise or turn the flywheel in the opposite direction of the engine rotation for approximately 30 degrees. This removes all play from the timing gears.
- If the No. 1 piston is not on the compression stroke, remove bolt (4) and turn the flywheel for 360 degrees counterclockwise. Install bolt (4). The No. 1 piston is now at the TC position.
- Install Tool (C) in the fuel injection pump housing, as shown. Push on Tool (C) and turn fuel injection pump camshaft (8). When Tool (C) engages the groove (slot) in the camshaft, the fuel injection pump is in the TC position for the No. 1 piston.

Typical example |
- Ensure that O-ring seals (5), (6), (7) and (9) are in position on the fuel injection pump housing and the governor. Put clean engine oil on the seals.
- Attach a hoist and put the fuel injection pump housing and the governor in position on the timing gear plate and the oil manifold. Install three nuts (11), two bolts (10) and the washers. Ensure that Tool (C) remains in place.

- Install Tool (B) on the fuel pump drive gear. Apply 68 N·m (50 lb ft) of force to the fuel pump drive gear with timing bolt (3) in position in the flywheel and Tool (C) in position in the fuel system. Apply this force in a clockwise direction when the engine is viewed from the front. Use Tool (B) and a suitable torque wrench. Hold the 68 N·m (50 lb ft) of force on Tool (B) and torque the drive gear bolt to a torque of 270 ± 25 N·m (200 ± 18 lb ft). Remove Tool (B) and Tool (C) from the fuel pump and remove bolt (3) from the flywheel.

- Use Tool (A) and turn the flywheel for two complete revolutions. When bolt (3) goes in the hole in the flywheel and Tool (C) is installed in the notch in the camshaft, the timing is correct.
- Install plugs (1) and (2) .
- Remove Tool (A). Install the electric starting motor.
- Install the valve mechanism cover. Refer to Disassembly and Assembly, "Valve Mechanism Cover - Remove and Install".
- Put cover (14) and the gasket in position. Install four bolts (15) .

- Put the fuel filter base, the gasket, and fuel filter (16) in position. Install two bolts (19) and the washers.
- Install tube assemblies (21) and (22). Connect wire (20). Connect hoses (17) and (18) .
- Put cover (24) in position. Install nuts (23) and six washers. Tighten nuts (23) to a torque of 27 ± 7 N·m (20 ± 5 lb ft).
