(1) Check the engine dataplate to find the Timing Guide.
(2) Measure the push rod travel when the piston is at 0.2032 inch Before Top Dead Center
(BTDC).
(3) Engine rotation speed. Reading differ when engine is turned fast/slow.
(6)
Correcting Injector Timing. If the reading on the push rod travel gauge is not within the limits
given in Table 3-3, increase or decrease the thickness of the cam follower gaskets to correct
the injection timing. See Table 3-4.
NOTE
Never change the cam follower gaskets to correct the injection timing until you check the
following:
That the timing tool is correctly installed.
That the gauges are correctly adjusted.
That the crankshaft has been rotated in the correct direction.
That the capscrews for the cam follower housing are tightened to 30 to 35 ft-lb torque.
(a)
If the indicator reading is higher than the specification, the timing is retarded. Increase the
gasket thickness to advance the injection timing (right hand rotation engine).
