Disassembly and Assembly

DISASSEMBLY

Remove electro-hydraulic coupling assembly. Refer to Disassembly and Assembly.

Remove differential assembly. Refer to Disassembly and Assembly.

Remove drive pinion oil seal, using oil seal remover (commercial service tool).

Fit drive pinion socket (A) onto drive pinion spline. Remove drive pinion lock nut, using the pinion nut wrench (B).

NOTE:

Left-handed screw is used.

Press drive pinion assembly out of gear carrier.

CAUTION:

Never drop drive pinion assembly.

Remove pinion front bearing inner race.

Remove collapsible spacer.

Remove pinion rear bearing inner race from drive pinion, using the separator (A) and the puller (B).

Using a brass rod or equivalent (A), tap pinion front bearing outer race evenly from the 2 cutouts on gear carrier and remove pinion front bearing outer race.

CAUTION:

Be careful not to damage gear carrier.

Using a brass rod or equivalent (A), tap drive pinion adjusting shim evenly from the 2 cutouts on gear carrier and remove drive pinion adjusting shim and pinion rear bearing outer race.

CAUTION:

Be careful not to damage gear carrier.

Perform inspection after disassembly. Refer to Inspection.

ASSEMBLY

Install a drive pinion adjusting shim of the same thickness as was installed prior to disassembly. Press pinion rear bearing outer race into gear carrier, using the drift (A) [SST: ST33200000 (NI-26082)].

CAUTION:

• At first, using a hammer, tap bearing outer race until it becomes flush to gear carrier.

Press pinion front bearing outer race into gear carrier, using the drift (A) [SST: ST33230000 (NI-25805-01)].

CAUTION:

• At first, using a hammer, tap bearing outer race until it becomes flush to gear carrier.

Press pinion rear bearing inner race to drive pinion, using the drift (A) [SST: ST23860000 ( — )].

CAUTION:

Never reuse pinion rear bearing inner race.

Check and adjust the tooth contact and back lash of drive gear and drive pinion following the procedure below.Assemble drive pinion into gear carrier.

CAUTION:

• Never assemble collapsible spacer.

• Apply gear oil to pinion rear bearing.

CAUTION:

• Never reuse pinion front bearing inner race.

• Apply gear oil to pinion front bearing.

NOTE:

Use removed drive pinion lock nut only for the preload measurement.

CAUTION:

Drive pinion lock nut is tightened with no collapsible spacer. Be careful not to overtighten it. While measuring the preload, tighten it by 5° to 10°.

CAUTION:

Apply differential gear oil to the side bearings.

Assemble collapsible spacer to drive pinion .

CAUTION:

• Be careful of the mounting direction of collapsible spacer.

• Never reuse collapsible spacer.

Assemble drive pinion into gear carrier.

CAUTION:

Apply gear oil to pinion rear bearing.

Assemble pinion front bearing inner race to drive pinion assembly.

CAUTION:

• Never reuse pinion front bearing inner race.

• Apply gear oil to pinion front bearing.

Using the drifts (A and C) and press stand (B), press pinion front bearing inner race to drive pinion as far as drive pinion lock nut can be tightened.

Apply anti-corrosion oil to the thread and seat of drive pinion lock nut, and temporarily tighten drive pinion lock nut to drive pinion.

CAUTION:

Never reuse drive pinion lock nut.

Fit the drive pinion socket (A) onto the drive pinion. While holding drive pinion, tighten drive pinion lock nut within the limits of specified torque so as to keep the pinion bearing preload within a standard values, using the pinion nut wrench (B) and the preload gauge (C).

CAUTION:

• Adjust the lower limit of the drive pinion lock nut tightening torque first.

• If the preload torque exceeds the specified value, replace collapsible spacer and tighten it again to adjust. Never loose n drive pinion lock nut to adjust the preload torque.

• After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rotation malfunction, and other malfunctions.

Install differential assembly. Refer to Disassembly and Assembly.

CAUTION:

Never install rear cover at this timing.

Check and adjust drive gear runout, tooth contact, and drive gear to drive pinion backlash. Refer to Adjustment.

Remove dummy cover set, then install rear cover, and side oil seal. Refer to Disassembly and Assembly.

Check total preload torque. Refer to Adjustment.

Using the drift (A) (commercial service tool), install drive pinion oil seal within the dimension (D) shown as follows.

CAUTION:

• Never reuse oil seal.

• When installing, never incline oil seal.

• Check that the oil seal lip is filled up with grease.

• Apply gear oil lightly and evenly onto the outer circumference of oil seal.

Install electro-hydraulic coupling assembly. Refer to Disassembly and Assembly.

Inspection

INSPECTION AFTER DISASSEMBLY

Drive Gear and Drive Pinion

• Clean up the disassembled parts.

• If the gear teeth never mesh or line-up correctly, determine the cause and adjust or replace as necessary.

• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive gear and drive pinion as a set.

Bearing

• Clean up the disassembled parts.

• If any chipped (by friction), pitted, worn, rusted or scratched marks, or unusual noise from the bearing is observed, replace as a bearing assembly (as a new set).

Oil Seal

• Whenever disassembled, replace.

• If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace them.
