CYLINDER BLOCK GP 1004948 - Caterpillar

Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Note: After the air supply connection has been made to the centrifugal oil filter regulator, verify that the regulator pressure is set to 207 kPa (30 psi). Maximum pressure setting for the regulator is 258.5 kPa (37.5 psi). Maximum air pressure supply to the regulator is 1723.6 kPa (250 psi)Centrifugal Oil Filter

Shut off air supply and open drain cock.
Loosen clamp (14) and nut (5). Remove cover (8) from filter body (16).
Remove O-ring seal (13) from the base.
Remove the rotor assembly from spindle (10). Lift the rotor assembly carefully so the bearings are not damaged.
Use tool (A) to hold the rotor assembly and remove nut (6).
Remove rotor body (12) and separation cone from rotor base (15). Clean stand tube.
Remove cover (7) from rotor body. Remove paper liner (9) from the rotor body. Properly dispose of the paper liner. Use a plastic scraper to clean out all remaining sludge.
Clean the nozzles in rotor base (15). Do not enlarge the nozzles.
Inspect bearings (4) and (17) for excessive wear.
Inspect spindle (10) for excessive wear.
If there is minimal wear to bearing (4), bearing (17), and spindle (10) go to step 14. If there is considerable wear to bearing (4), bearing (17), and spindle (10) go to step 12.
Use tool (C) to measure the clearances between the bearing (4) and bearing (17) and spindle (10). The maximum clearance between bearing (4) and spindle (10) is 0.25 mm (0.010 inch).The maximum clearance between bearing (17) and spindle (10) 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.
Install a new paper liner (9) in rotor body and cover (8). Place O-ring seal on rotor base and rotor cover. Position rotor body (12) on rotor base (15).
Ensure that all of the rotor components are thoroughly clean before assembling the rotor. Failure to do
