VALVE LASH CHECK
WARNING
Do not use the engine starter to turn the flywheel. Failure to comply can cause injury to
personnel.
NOTE
All clearance measurements must be made with the engine stopped and the valves fully closed.
Otherwise, incorrect adjustments will be made resulting in engine damage.
Valve lash adjustment is not necessary if measurement is in the acceptable range.
Engine must be turned with the four large bolts on crankshaft retaining plate.
1. Remove crankshaft damper and damper pulley (WP 0104). Leave retaining plate and crankshaft pulley in
place.
2. Remove plug (Figure 2, Item 19) from timing hole on right front side of flywheel housing. Insert timing bolt
(Figure 2, Item 20) through timing hole.
3. Using four large bolts on crankshaft retaining plate, turn flywheel in direction of normal engine rotation until
timing bolt (Figure 2, Item 20) engages hole in flywheel.
4. If flywheel is turned beyond point of engagement, turn flywheel in opposite direction approximately 30 degrees.
Then turn flywheel in direction of normal engine rotation until timing bolt (Figure 2, Item 20) engages hole in
flywheel.
