Operational testing
Operational testing need only be carried out if it
is suspected that the centrifugal oil cleaner is
malfunctioning. For example, if the dirt deposit
is abnormally small given the distance driven.
The rotor rotates very fast and should continue to
turn when the engine has stopped.
1. Run the engine until it reaches normal oper-
ating temperature.
2. Turn off the engine and listen for the sound
from the rotor. Use your hand to feel if the
filter housing is vibrating.
3. If the filter housing is not vibrating, disman-
tle and check the centrifugal oil cleaner.
