RE A R DIFFERENTIAL - NINETY HEAVY DUTY ASSEMBLY NOTE: If thrust washers were removed from the side following procedure. DO NOT allow oil to contact any holes or bolts that are to be Loctited. Position the smaller case half with the open side 26. Assemble the crosspins, pinions and thrust washers, lubricate the thrust washers with 27. Fit the crosspin assembly on to the side gear already contained in the differential case half, 28. Fit the other side gear to the crosspin assembly ensuring that all the gears locate correctly. 29. Fit the two case halves together, maintaining the alignment marking and ensuring correct gear m (22 to 27 Ibf (30 to 36 Nm). 31. Check that the serial number marked on pinion end face matches that marked on the crown wheel. 32. Ensure that the differential housing flange and crown wheel are thoroughly clean. Align the crown case, fit the bolts and washers and tighten evenly. 33. If removed, press on the differential roller bearings. 34. Place the differential housing complete with crown wheel and bearings i n the pinion housing. 35. Fit the bearing caps and bolts. Do not tighten the bolts. 36. Fit the bearing adjusting nuts and adjust to obtain zero end-float. 37. Tighten the bearing cap bolts. run-out. This should not exceed If excessive run-out is recorded remove the crown wheel and examine crown wheel and can be corrected only by renewing t h e differential 39. When satisfied that run-out is within t h e specified limits remove the differential housing from . . . . , ... .I. 40. Remove the crown wheel bolts and refit them using Loctite ‘Studlock’. Evenly tighten the bolts to Drive pinion 41. Fit the pinion head bearing track and the original shim to the pinion housing using service tools and R O I f the original shim was damaged or mislaid use a shim of at least (0.050 in) thickness. 42. Fit t h e pinion outer bearing track to the pinion housing with service tool and R O NOTE: Instructions 41 and 42 are out in one operation as illustrated. 43. Fit the pinion head bearing to the pinion using continued service tool 3 |
