Maintenance and Service
The centrifuge should be cleaned at regular intervals ensuring that the thickness of the deposit inside the rotor does not exceed approximately 35.0 mm (1.38 inch). This operation is normally carried out after a specified period of operational use and may be combined with other maintenance procedures.Maintenance Procedure
Stop the flow of oil to the centrifuge by stopping the engine. Ensure that the centrifuge has come to a complete stop and allowed to cool before proceeding.
Remove the band clamp, unscrew the cover nut, and remove the centrifuge cover assembly.
Allow the oil to drain out of the rotor assembly. The draining may be assisted by raising the rotor on the spindle. Withdraw the rotor assembly vertically upwards from the spindle. The rotor should be removed and replaced on the spindle with care to ensure that the rotor bearings are not damaged.
Unscrew the rotor cover nut and separate the rotor cover from the rotor body.
Remove the stand tube.
Remove sludge deposits from inside the rotor cover using a spatula. Clean the rotor components using a suitable cleaning fluid. Ensure that all rotor components (including the two nozzles located in the rotor body), are thoroughly cleaned and free from debris before reassembly.
Examine the rotor assembly O-ring for damage and renew if necessary.
Fit a new paper insert into the rotor cover.
Reassemble the rotor assembly ensuring that the rotor cover slot and rotor body pin are aligned. Hand tighten the knurled rotor nut. Do not interchange rotor covers.
Replace the rotor on the spindle and check that the rotor spins freely.
Examine the centrifuge body O-ring for damage and renew if necessary.
Install the centrifuge cover and tighten the cover nut to 13 2 N m (115 18 lb in).
Install the band clamp and tighten 13 2 N m (115 18 lb in). The band clamp must be securely fitted during operation of the centrifuge.
With the centrifuge running, check all joints for leaks.Maintenance Action
Every Oil Drain Interval:
Clean Rotor Assembly / Replace Paper Insert
Inspect Centrifuge Body O-Ring & Rotor Body O-ring. Replace if Damaged.
Check Cover Nut O-Ring for leaks and replace if necessary.
Inspect Rotor Bearings for wear and replace Rotor Body Assembly if necessary.
Inspect Spindle for wear and replace Centrifuge Body Assembly if necessary.Spare Parts List for 1W-4191 Centrifugal Oil Filter Gp
