M/T Differential Carrier Bearing Preload Adjustment

  1. At normal room temperature, measure the starting torque of the differential assembly by rotating it in both directions with the special tool and a torque wrench (A).
    Standard:
    3.43−4.51 N·m (35−46 kgf·cm, 30−40 lbf·in.)

  1. If the carrier bearing preload is not within the standard, select a 81 mm thrust shim that will provide the correct preload:
    • Compare the bearing preload you got on the first try with the specified preload of 3.43−4.51 N·m (35−46 kgf·cm, 30−40 lbf·in.).
    • If the preload you measured was less than specified, subtract it from the specified preload.
    • If the preload you measured was more than specified, subtract it from the specified preload.
    For example, with a 2.50 mm (0.098 in.) thrust shim:
    (1) specified
    4.51 N·m (46 kgf·cm, 40 lbf·in.)
    − you got less
    2.55 N·m (26 kgf·cm, 23 lbf·in.)
    1.96 N·m (20 kgf·cm, 17 lbf·in.) less

    (2) you got more
    5.29 N·m (54 kgf·cm, 47 lbf·in.)
    − specified
    4.51 N·m (46 kgf·cm, 40 lbf·in.)
    0.78 N·m (8 kgf·cm, 7 lbf·in.) more

    NOTE: Each shim size up or down from standard makes about 0.3−0.4 N·m (3−4 kgf·cm, 2.6−3.5 lbf·in.) difference in preload.
    In example (1), your preload was 1.96 N·m (20 kgf·cm, 17 lbf·in.) less than standard, so you need a thrust shim five sizes thicker than standard (try the 2.65 mm (0.104 in.) 81 mm thrust shim, and recheck).
    In example (2), your preload was 0.78 N·m (8 kgf·cm, 7 lbf·in.) more than standard, so you need a thrust shim two sizes thinner (try the 2.44 mm (0.096 in.) 81 mm thrust shim, and recheck).
