[1] – Remove bell cranks from both sides of differential lock shaft.
[2] – Hold brake bell crank in an engaged position to keep brake disks in position for easier assembly.
a. Install a bolt (A) for this procedure.
b. Install the external bell crank.
c. Turn brake bell crank (B) clockwise until tight and place a tie wrap between end of external bell crank and installed bolt (A) to keep pressure on brake disks.
[3] – Remove suction manifold and suction screen from case.
[4] – Remove right axle and axle housing assembly.
[5] –
โNOTE:
Bevel ring gear and bearing may remain in side cover or stay on pinion shaft.
Remove differential pinion shaft and bevel gear assembly (B).
[6] – Simultaneously pull out differential assembly (C) with differential lock shaft and fork assembly (D).
[7] – Remove differential lock shaft assembly from the differential assembly.
[8] – Inspect all parts for wear or damage. Replace as necessary.
[9] –
โNOTE:
Protect differential lock shaft oil seals during assembly if they are still in the housings.
Place differential lock shift fork (A) on collar (B) and simultaneously install differential assembly (C) with differential lock shaft and fork assembly.
[10] – Temporarily insert bevel gear pinion shaft (D) to center and align brake friction disks.
[11] – Install bevel gear and bearing assembly to bevel gear shaft and insert into bearing housing and brake disks.
[12] – Rotate brake cam shaft to move brake disks to applied position. Check for brake hold with bevel gear shaft assembly.
[13] – Fasten outer hex of brake cam shaft in applied position with Vice-Grip or wrench to hold brake disks in alignment. Remove bevel gear assembly and install to gear case.
[14] – Ensure that two locating dowels (E) are installed to housing.
[15] – Apply grease to bearing housing bore surface to retain backlash shim. Install backlash shim removed at disassembly.
[16] – Apply Form-in-Place gasket maker to housing mounting flange (F).
[17] –
โNOTE:
If necessary, rotate the bevel gear pinion shaft to align it to the brake disk splines when installing the axle housing to the gear case.
Install housing to gear case. Install and tighten cap screws to specification.
[18] –
IMPORTANT:
Make sure that the free end of the suction screen is aligned and fitted to the socket in the transmission right side cover during assembly. Improper installation could result in crushing of the suction screen and subsequent hydraulic pump failure.
Install suction manifold and suction screen. Make sure the oil suction screen is properly aligned to the side cover during installation. (See Remove and Install Oil Suction Screen in Section 70, Group 10.)
