WARNING
After the engine is operated, all parts are at high temperature, so do not replace the filter element immedi-
ately. Wait for all parts to cool down before starting the work.
NOTICE
q
If the engine is operated without the filter element, the turbocharger and aftercooler will become dirty
and their performance will lower and that can cause engine problems such as overrun caused by suc-
tion of oil. Therefore, do not start the engine without the filter element.
q
The filter element cannot be cleaned. If the filter element is cleaned, the filter performance lowers. As a
result, the turbocharger and aftercooler become dirty and the crankcase pressure increases. Never
reuse the filter element since it can cause an engine problem.
q
After the filter element is replaced, if KCCV is not assembled correctly, oil or blow-by gas may leak.
Replace the filter element in the correct procedure.
Prepare the special wrench for KCCV and a container to catch the oil.
The KCCV ventilator is located at the positions shown in the
figure on the right.
For how to use the special wrench, see the figure on the right.
1. Using the special wrench, loosen ring (3) of KCCV ventila-
tor (1).
