6.4.3.11 Operation 40. Cleaning of centrifugal oil filter rotor of the engine
Cleaning of centrifugal oil filter rotor of the engine shall be carried out together with
oil change in the diesel crankcase.
To clean the centrifugal oil filter rotor, it is required to do the following:
- unscrew nut 1 (figure 6.4.27) and remove cover 2;
- insert screwdriver 5 or a cane between filter casing and rotor bottom to prevent
rotor 9 from rotating, and turning the rotor nut by means of key 4, remove rotor
bowl 3;
- remove cap 6, propeller 7 and mesh filter 8 of the rotor;
- remove sediment from inner walls of the rotor bowl by means of a non-metallic
scraper;
- clean all the parts, rinse them in a cleaning solution and blow them with com-
pressed air;
- assemble the filter performing disassembling operations in the reverse order. Be-
fore assembling rotor casing and bowl, grease the O-ring with engine oil;
- match the balance marks on the rotor casing and bowl;
- screw in the bowl retaining nut with little effort until the bowl fully sets onto the ro-
tor;
- the rotor shall rotate freely, without jamming;
- mount cover 2 and tighten nut 1 with the torque from 35 to 50 Nm.
Note – After the engine stop, noise from the rotating rotor shall be heard for 30-60
sec which indicates that the filter is operating normally.
