CYLINDER GP 6G4415 - Caterpillar

Carrier Bore Preparation
Inspect the joint faces of the carrier bearing cap for wear or damage. Machine the faces flat if necessary.
Install the bearing caps and tighten to the torque specification listed in the applicable Disassembly and Assembly manual.
Clamp the carrier on the table of a precision boring machine. Find the centerlines of diameter (A) and the bearing bore opposite the one being repaired, to establish the centerline of the new bearing bore.Note: If the bore being repaired still has some surface that is not worn, use that surface and the opposite bore to establish the center-line of the new bearing bore, instead of using diameter A.
Machine the damaged bore to the dimensions shown in Illustration 5 and Table 4. After machining, the new bearing must be in alignment with the opposite bore within 0.15 mm (0.006 inch).Cap Preparation
Remove the bearing cap.
Drill and ream a 7.76 mm (0.305 inch) diameter hole in the cap as shown in Illustration 6
Press a 6F-0698 Dowel into the hole. The dowel must extend 4.5 mm (0.18inch) above the surface of the cap.

Note: The following is an optional method for preliminary cage preparation.
Clamp a 5T-5966 Bearing Cage on the outside diameter in a lathe. Do not overtighten the jaws.
Machine the cage bore for the bearing and cut the threads for the retaining nut. Refer to Illustration 7 for the dimensions
Drill a 9.20 mm (0.362 inch) diameter hole, as shown in Illustration 7.

If necessary, trim the bearing cage flush with the side of the carrier bore.
Machine a slot in the new cage for the nut lock tab. Use the bearing cap as a template.
Assemble the differential carrier using standard Service Manual procedures, except as noted in Step 4 (992C)
Clean the outside diameter of the bearing cup and inside diameter of the cage with Quick Cure Primer. Apply a thin coat of Bearing Mount to the outside diameter of the cup before final assembly. Be sure that necessary adjustments are made immediately after assembly.
