1. CLEANING OF FILTER

After stopping the engine completely or isolating the filter from the
lubrication system by means of a valve:
1.1. Release and remove the clamp (1).
1.2. Remove the cover and check the top bearing for damage or
wear. Inspect the O-ring (2) and replace it if necessary.
1.3. Lift the rotor unit and allow oil to flow through the nozzles,
before separating the rotor from the filter body. Secure the filter
body and undo the rotor nut (3). Separate the cover from the rotor
body and dismantle the central support tube (4-5).
1.4. If there is a sheet of paper at the bottom of the rotor, remove it,
since it contains accumulated impurities. If there is no sheet of
paper, remove sludge from the rotor inside with a wooden spatula
or an adequate wooden object and clean the interior of the rotor
with a cloth. Put a new filtering paper (7).
1.5. Clean the nozzle with a bronze wire to verify that oil can
circulate freely. Make sure that the inside of the shaft is

unobstructed by impurities. Check the shaft bearings for damage
and excessive wear. Inspect the O-ring (6) for good condition and
replace it if necessary.
1.6. Clean and wash the central support tube and make sure the
filter holes are unobstructed.
1.7. Re-assemble the whole rotor and torque the nut (3) to 9.5 to
10.8 Nm (1 to 1.10 kgm).
1.8. Check the bottom bearings fitted in the filter body for damage
or wear.
1.9. Remove the cap of the shutoff valve (8) and take out the unit.
Check the spring and valve for damage and freedom of motion.
Inspect the seal (9) and replace it if found damaged.
1.10. Re-assemble the shutoff valve unit.
1.11. Re-assemble the whole filter and check for free rotation of the
rotor unit. Then, put the filter cover and secure it with the clamp.
1.12. With the filter in service, check for possible leaks at seals and
fittings.
