Close valve (2) to centrifugal oil filter (1).
Loosen clamp (16) and nut (5). Remove cover (9) from filter body (18).
Remove O-ring seal (14) from the body.
Remove the rotor assembly from spindle (11). Lift the rotor assembly carefully so the bearings are not damaged.
Use tool (A) to hold the rotor assembly and remove nut (7).
Remove stiffener plate (6).
Use tool (B) to remove rotor cover (8) from rotor base (17). Remove O-ring seal (13) from the base. Remove paper liner (10) from the rotor cover. Properly dispose of the paper liner. Use a plastic scraper to clean out the inside of rotor cover (8).
Remove stand tube (12) from rotor base (17) and clean the stand tube.
Clean the nozzles in rotor base (17). Do not enlarge the nozzles.
Inspect bearings (4) and (15) for excessive wear.
Inspect spindle (11) for excessive wear.
If there is minimal wear to bearing (4), bearing (15), and spindle (11) go to step 14. If there is considerable wear to bearing (4), bearing (15), and spindle (11) go to step 13.
Use tool (C) to measure the clearances between the bearing (4) and bearing (15) and spindle (6). The maximum clearance between bearing (4) and spindle (11) is 0.25 mm (0.010 inch).The maximum clearance between bearing (15) and spindle (11) is 0.20 mm (0.008 inch).If the rotor bearings and the spindle are not within specifications, replace the parts.Note: The spindle and the filter body are replaced as a complete assembly. The rotor assembly is replaced as a complete assembly.Before you assemble the centrifugal oil filter, thoroughly clean all of the parts and inspect all of the parts. Replace parts that are damaged or worn.
Ensure that all of the rotor components are thoroughly clean before assembling the rotor. Failure to do so can cause an out of balance condition that can cause rapid wear to the bearings and the spindle.
Install stand tube (12) on rotor base (17).
Install a new paper liner (10) in rotor cover (8). Place O-ring seal (13) on rotor base (17). Position rotor cover (8) on rotor base (17).
Install stiffener plate (6).
Use tool (A) to hold the rotor assembly and install nut (7).
Install the rotor assembly on spindle (11). Install the rotor assembly carefully so the bearings are not damaged.
Install O-ring seal (14) on filter body (18).
Install cover (9) and clamp (16) on filter body (18). Tighten clamp (16) and nut (5).
Open valve (2) to centrifugal oil filter (1).
Check the centrifugal oil filter for leaks. Feel the centrifugal oil filter for excessive vibration.
