Differential Assembly
- Remove bearing outer race and adjustment shims from transaxle case. Mount differential assembly in converter housing (with race installed). Install bearing outer race onto selector gauge (49 D017 2A2A-Shim Selector Tool Set). Set selector gauge on differential. Set transaxle case on selector gauge.
- Eliminate gap on selector gauge by turning collars of selector gauge. Mount spacing collars between transaxle case and clutch housing. See Fig 1. Tighten bolts to 14-18 ft. lbs. (19-25 N.m).
- Using rods on collars of selector, turn selector in a direction which widens the gap between collars of selector. Turn selector (to widen gap) until it will no longer turn. This will seat bearing race.
- Turn selector collars in opposite direction until gap is closed. Mount preload adapter into differential until it contacts pinion shaft. Using INCH-lb. torque wrench, rotate differential. See Fig 2. Turn selector collars until turning torque is .26-6.59 INCH lbs. (.03-.74 N.m).
- Using feeler gauge, measure clearance of gap between selector collars. See Fig 1. Measure around entire circumference of selector. Select shims equal to maximum clearance measured. Shims range in thickness from .008" (.20 mm) to .022" (.55 mm) in increments of.002" (.5 mm).
- Unbolt converter housing from transaxle case. Remove selector gauge. Install selected shims in transaxle case. Install bearing race. Set differential in transaxle case. Install converter housing. Tighten bolts to 14-18 ft. lbs. (19-25 N.m).
- Position preload adapter into differential until in contacts pinion shaft. Measure bearing preload with INCH-lb. torque wrench. See Fig 2. Differential bearing preload should be .26-6.59 INCH lbs. (.03-.74 N.m). If bearing preload is not within specification, repeat steps 1) - 5).
