Bearing Thickness Measurement
b. Assemble new righthand bearing into bearing preload tool T93P-4220-A, or equivalent, then torque preload tool to 25 ft lb.
c. Using a suitable depth micrometer, measure thickness of bearing. Record this dimension as D, righthand side.
d. Repeat above procedure on lefthand bearing. Record this dimension as D, lefthand side.
14. Determine thickness of righthand bearing shim as follows:
a. Subtract dimension D righthand side from master bearing standard thickness of 0.8695. Record this measurement as dimension E, righthand
side.
b. Add dimension E, righthand side, dimension C and preload standard of 0.0200. Result is righthand shim initial thickness.
c. Round off initial shim thickness to nearest available shim thickness for final righthand side shim size.
15. Determine thickness of lefthand bearing shim as follows:
a. Subtract dimension D, lefthand side from master bearing standard thickness of 0.8695. Record this measurement as dimension E, lefthand
side.
b. Add dimension E, lefthand side to dimension B, then subtract backlash standard of 0.006 to determine lefthand shim initial thickness.
c. Round off initial shim thickness to nearest available shim thickness for final righthand side shim size.
16. Mark lefthand and righthand shims for later assembly.
17. Place righthand and lefthand differential case bearings onto their proper positions, then using a suitable press, seat bearings onto differential case.
