Operation of Caterpillar engines with improper valve
adjustments can reduce engine efficiency. This reduced efficiency could result in excessive fuel usage
and/or shortened engine component life.
This maintenance is recommended by Caterpillar
as part of a lubrication and preventive maintenance
schedule in order to help provide maximum engine
life.
Ensure that the engine is stopped before measuring
the valve lash. To obtain an accurate measurement,
allow the valves to cool before this maintenance is
performed.
Refer to the Service Manual for more information.
Check the equalizer bar pins for looseness and for
unusual wear. The pins are located on the top of the
track roller frame behind the idler.
If unusual wear is evident, see the Service Manual or
consult your Caterpillar dealer for an inspection and
for repair instructions.
