Bearing Preload (Countergear Shaft)

1987 Jeep Comanche Laredo, 2.5 H, RWD, AutomaticSECTION Bearing Preload (Countergear Shaft)
  1. Remove clutch housing, bearing retainer (if equipped), input shaft and mainshaft. Remove detent ball and spring. Install countergear shaft with bearings in transmission case.
  2. Ensure that 2 centering dowels are installed in right side of case. Install right half of transmission case and retain in position with 4 bolts (1 at each corner). Install bearing retainer and hold in position with Allen screws (if equipped). Finger tighten all retaining bolts and screws.
  3. With case securely attached to transmission stand, turn case so front of transmission is facing up. Press on adapter by hand while rotating shaft to seat bearings.
  4. On transmission cases which use 2 roll pins to position case halves, tighten following bolts in sequence: 4 case bolts and 4 retainer plate bolts. On transmission cases which use one pin to position case halves, install clutch housing.
  5. Retain housing to case by using 4 bolts, 2 on each half of case. Tighten in sequence, clutch housing bolts, case bolts and retainer plate bolts. Remove clutch housing. Check offset between case halves with Gauge Block (.0310FZ) and dial indicator. If offset exceeds .001" (.03 mm), remove all components and repeat procedure.
  6. On all models, center hole in gauge block on countergear shaft. Install dial indicator so indicator tip rests against bearing outer race surface. Rotate indicator through one complete revolution. Warpage between case halves must not exceed .001" (.03 mm).
  7. If specification is exceeded, align bearing race by tapping with a plastic mallet. After aligning outer bearing race, check that drag is not added to cluster shaft and recheck warpage. To reduce drag, loosen and retighten 2 front case bolts.
  8. With dial indicator in place on countergear shaft bore (tip resting on outer race), zero dial indicator at "2" or "0". Move indicator so tip is resting on front face of case. See Fig 1. Shims are available from .089-.134" (2.25-3.40 mm) in .002" (.05 mm) increments.
  9. Note dial indicator reading. Add .004" (.10 mm) to reading. Calculate shim to be installed between bearing and countergear shaft. Round off result to nearest .002" (.05 mm). Remove countergear shaft. Remove front bearing and insert shim of determined thickness with inside chamfer facing gear. Reinstall bearing.
