Rework Procedures
Bearing Support Diameters and Gear Thrust Faces
Metal spray all surfaces and bores before machining. Refer to Illustration 43.
Illustration 43 g03704302
Spider gear thrust faces, bores, and carrier faces after metal spray operation.
Machine all thrust faces and bores according to specifications.
Illustration 44 g03704304
Machine bearing thrust face and bore.
Fix the spider in the flange.

Installation of spider prior to assembly with carrier halves and bolts.
Assemble the carrier.Note: Assemble 8W-6993 Differential Housing As and 5T-5775 Differential Housing As with spider shaft in place. Install bolts and tighten to 1006 102 N m (742 75 lb ft) torque.

Assemble the carrier prior to machining the support bearing diameters.
Fix the carrier assembly into a lathe and align for machining.
Illustration 47 g03704310
Use two indicators to align the assembled carrier for final machining of side bearing trunnions.
Reworking Pinion Bores, Pinion Thrust Face, and Split Face
This operation requires a numerically controlled machine or an indexing table. The positioning of the part manually is not recommended.
Metal spray all areas that need to be reworked.

Differential housing after metal spray operation. Housing is ready to begin machining.
Attach housing to machine base, but do not tighten completely. Both plain and flange differential housing can be located using the keyway and held in place with a stepped universal washer.
Illustration 49 g03704320
Secure housing to machine base using bolt and universal washer.
Make sure that split face is parallel to machine table and align bores to be machined. Secure housing to table.
Illustration 50 g03704323
Align and secure the housing.
Note: The plain half of the differential housing uses the same locating and machining operation as the flange half of the differential housing. Check parallel dimensions of cross shaft bores, thrust faces, and split faces using the same fixture setup.

Machine pin bore.
Center (zero) the boring bar to the split line of the carrier. A parasitic block must then be bolted in place. This determines the relationship of the bore. Due to the metal spray operation a possible four-cut procedure may be required with two rough bore cuts, a semi-finish, and a finish cut.
