Engine Valve Lash - Inspect/Adjust
SMCS - 1102-025
To prevent possible injury, do not use the starter to turn the flywheel.
Hot engine components can cause burns. Allow additional time for the
engine to cool before measuring valve clearance.
This engine uses high voltage tocontrol the fuel injectors.
Disconnect electronic fuel injector enable circuit connector to prevent
personal injury.
Do not come in contact with the fuel injector terminals while the engine
is running.
Note: Valve lash is measured between the rocker arm and the valve bridge. All measurements and
adjustments must be made with the engine stopped and the valves fully closed.
Valve Lash Check
Anadjustment is not necessary if the measurement of the valve lash is in the acceptable range in Table 1.

Adjust the valve lash according to Table 2.
Lightly tap the rocker arm with a soft mallet. This will ensure that the lifter roller seats against the
camshaft's base circle.
a.
Loosen the b. adjustment locknut.
Place the appropriate feeler gauge between rocker arm and thevalve bridge. Then, turn the
adjustment screw in a clockwise direction. Slide the feeler gauge between the rocker arm and the
valve bridge. Continue turning the adjustment screw until a slight drag is felt on the feeler gauge.
Remove the feeler gauge.
c.
Tighten the adjustment locknut to a torque of 30 ± 7 N·m (22 ± 5 lb ft). Do not allow the
adjustment screw to turn while you are tightening...
