crankshaft pulley.

21.

Rotate crankshaft clockwise 360 degrees until timing bolt engages non-threaded hole in flywheel.

NOTE

No. 1 piston is on compression stroke if intake and exhaust valves

are closed and rocker arms can be moved by hand.

No. 1 piston is on exhaust stroke if intake and exhaust valves are

open and rocker arms cannot be moved by hand.

22.

Position No. 1 piston at TC and make identification for the correct stroke (compression or exhaust).

Refer to table 2 for correct injector sequence.

Table 2. Crankshaft Positions for Fuel Timing.

Check/adjust with No. 1

Injectors 3-5-6

piston on TC compression stroke

Check/adjust with No. 1

Injectors 1-2-4

piston on TC exhaust stroke

NOTE

Set timing for No. 1 injector last. This will be correct position to
