After every 250 service hours
Perform the previous MS and the following
operations:
Operations 13. Centrifugal oil filters of
GB.
• Remove the nut (1) and cap (2).
• Insert the screwdriver (5) or a rod be-
tween the filter casing and the rotor bot-
tom to prevent rotation of the rotor (3),
and turning the rotor nut with the key
(4) remove the carrier of the rotor (3).
• Remove the cover (6), the impeller (7)
and filter mesh (5) of the rotor. As ne-
cessary, clean and rinse the mesh.
• Using a non-metallic scraper, remove
deposits from the inner walls of the ro-
tor carrier.
• Clean all parts, rinse them in diesel fuel
and blow with compressed air.
• Assemble the filter, performing the dis-
assembling operations in the reverse
order. Before assembling the carrier
with the rotor housing, lubricate the O-
ring with motor oil.
• Align the balance marks on the carrier
and the rotor housing. Screw the carrier
fastening nut with a small force until the
carrier fully lands on the rotor.
• The rotor must rotate freely without
jamming.
• Install the cap (2) and tighten the nut
(1) to a torque of 35 to 50 N•m.
Note: After the engine stops, a noise of
rotating rotor must be heard for 30 to 60
seconds. This indicates that the filter is
working properly.
