Drive Pinion: Assembly
WARNING: This page is about a different variant/trim than selected.
- Install the plugs with new O-rings.NOTE: Apply CVTF to the O-rings.
Tightening torque:
25 N.m (2.5 kgf-m, 18.4 ft-lb)
- Using the ST, install the oil seal.NOTE:
- Apply CVTF to the press-fitting area.
- Make sure to install in the right direction.
Preparation tool:
ST: INSTALLER (20099AE020)
- Select the drive pinion shim.
- Using the ST and a micrometer, measure the dimension "A" from the ST end face to the drive pinion (gear portion) end face.
Preparation tool:
ST: GAUGE (499575600)
- Using the ST and a press, press-fit a new taper roller bearing inner race (front side).
Preparation tool:
ST: INSTALLER (499277200)
- Using a press, press-fit a new taper roller bearing outer race (A) and a new taper roller bearing (rear side) (B).NOTE: Press in to a position where the taper roller bearing rotates smoothly without play.
- Install a new O-ring (B) and the drive pinion collar (A).NOTE: Apply the differential gear oil to O-ring.
- Tighten the lock nuts using ST1 and ST2.CAUTION: Be sure to use a new lock nut.NOTE: Tighten the lock nut with ST1 and torque wrench aligned straight.
Preparation tool:
ST1: WRENCH (499787700)
ST2: HOLDER (18667AA010)
Tightening torque:
Calculation formula T = 116 N.m (11.8 kgf-m, 85.6 ft-lb) x L/(100 mm (3.94 in) + L) T: Tightening torque L: Effective length of torque wrench NOTE: If the effective length of the torque wrench used is unknown, consult the manufacturer of the torque wrench. - Measure the initial load of the taper roller bearing using the ST and a spring scale.CAUTION: Before checking the initial load, apply differential gear oil to the roller part of taper roller bearing, and rotate it several times to measure the value.NOTE: If it exceeds the standard value, replace the taper roller bearing.
Initial load:
1.5 - 4.7 kgf (14.33 - 46.37 N, 3.22 - 10.42 lbf)
Preparation tool:
ST: HOLDER (18667AA010)
- Crimp the lock nut in 2 locations.
- Using the ST and a micrometer, measure the dimension "B" from the ST end face to the taper roller bearing outer race end face.
Preparation tool:
ST: GAUGE (499575600)
- Using the following calculation, calculate an appropriate thickness "T" of the drive pinion shim.
NOTE: Adjust using 1 - 3 pieces.T = (H2 - H1) - 6.55 mm (0.258 in)
T Drive pinion shim thickness (mm (in)) A Measured value (mm (in)) of step (1) B Measured value (mm (in)) of step (8) 6.55 mm (0.258 in) Constant - Using the ST and a micrometer, measure the dimension "A" from the ST end face to the drive pinion (gear portion) end face.
- Install the drive pinion shim and drive pinion.CAUTION: Be careful not to bend the drive pinion shim.NOTE: Apply differential gear oil to the oil seal lip.
Tightening torque:
70 N.m (7.1 kgf-m, 51.6 ft-lb)
