Engine Valve Lash
To prevent possible injury, do not use the starter
motor to turn the flywheel.
Hot engine components can cause bums. Allow
additional time for the engine to cool before
adjusting valve lash.
Initial valve lash adjustment on new, rebuilt or
remanufactured engines is recommended at the first
scheduled oil change interval due to initial wear and
seating of valve train components. Subsequent
adjustments should be made at Every 2000 Hour
This maintenance is recommended by Caterpillar as part
of a lubrication and preventive maintenance schedule to
provide maximum engine life.
