OPERATION
Komatsu Closed Crankcase Ventilation (KCCV)
KCCV is a device to clean the gas discharged from the engine
crankcase with the filter element and return it to the engine air
intake system.
NOTICE
•
The KCCV filter element needs to be replaced every
2000 hours.
•
If the engine is operated without KCCV filter element
or if a filter element other than the Komatsu genuine
element is used, the engine sucks oil and foreign ma-
terial which can cause a failure. Always install Komat-
su genuine KCCV filter element.
•
The filter element cannot be flushed. Never reuse the
filter element since it can cause a performance decre-
ment of engine, and it result in a failure even if it is
cleaned.
