Valve Lash Limit Chart
5. Measure the valve lash by inserting a feeler gauge between the rocker arm socket and crosshead. Refer to Valve Lash Limit Chart for the correct
specifications.
Measure the valve lash at the following rocker arms:
^
INTAKE 1-2-4
^
EXHAUST 1-3-5.
6. If adjustment/resetting is required, loosen the lock nut on rocker arms and turn the adjusting screw until the desired lash is obtained:
INTAKE: 0.254 mm (0.010 inch)
EXHAUST: 0.508 mm (0.020 inch)
Tighten the lock nut to 24 Nm (18 ft. lbs.) and re-check the valve lash.
7. Using the crankshaft barring tool, rotate the crankshaft one revolution (360°) to align the pump gear mark to the 6 o'clock position in relation to
the TDC mark on the gear housing cover (Fig. 49).
8. With the engine in this position (pump gear mark at 6 o'clock), valve lash can be measured at the remaining rocker arms:
^
INTAKE 3-5-6
^
EXHAUST 2-4-6
Use the same method as above for determining whether adjustment is necessary, and adjust those that are found to be outside of the limits.
