F. Remove the bearings, O-rings and spacer from the pinion.
DIFFERENTIAL Removal and Disassembly (See Figure 7) A. If the hypoid ring and pinion are not to be replaced, check the contact pattern before disassembly. The pattern and gear clearance are used as references for assembly. See the ASSEMBLY section for the procedures. B. Loosen the nut for the output gear. C. Loosen the thrust bolt for the ring gear. Remove the bearing caps, adjusting nuts and the ring gear assembly. D. Remove the case for the ring gear and differential from the transmission housing. E. Remove the nut for the output gear. Remove the output gear then pull the pinion from the transmission housing.
G. If necessary, remove the ring gear from the case half. Remove the bolts from the case halves, then remove the spider and side gears. Inspection A. Check the hypoid and ring gear for wear. Inspect the differential pinions and axle gears for worn teeth. Inspect the spider for wear where the gears turn. There must not be any clearance between the spider and the holes for the spider in the differential case. B. Check all bearings for damage. Replace the bearing cups and cones if there is any damage. Assembly And Installation - H40-60XL (See Figure 8) NOTE The ring and pinion gear must be replaced as a set.
