Disassembly
1. Remove bolts and take off housing cover. (See Figure 1).
Figure 1.2. Take off washer, outer and inner discs, the first pressure ring, and the first axle bevel gear. (See Figure 2).
Figure 2.3. Remove the differential axles from the housing together with the bevel gears. (See Figure 3).
Figure 3.4. Remove the second axle bevel gear, the second pressure ring, and the second disc brake assembly from the housing. (See Figure 4).
Figure 4. The correct order of installation of the discs should not be altered.Inspection of Individual Parts
Differential Housing
Check run-up surfaces for the washer for wear and distress. Look for wear on guide grooves for outer disc and pressure rings.Housing Cover
Check run-up surfaces for the washer for wear and distress.Pressure Ring
Check the guide noses and run-up surfaces for wear and pitting. Pressure rings must move easily in the differential housing.Axle Bevel Gears
Check the run-up surfaces for the washers for wear. The inner discs must move easily on the toothing of the axle bevel gears.Discs
Inspect inner and outer discs for wear. Guide noses of the outer discs and the toothing of the inner discs must not be damaged.Washers
Check the washers for wear. Some evidence of wear is normal, but excessive wear requires replacement.Assembly
1. Before assembling, lubricate all running surfaces of the discs, the pressure rings and the differential axles with gear oil.2. Place the housing on a bench with the large bore up. Install the disc face down in the housing. (See Figure 5).
Figure 5.3. Install the outer discs and inner discs in the housing. Be sure to install the discs in the same order that they were in when removed, making sure that one outer disc is placed against the housing and one is against the cover. (See Figure 6).
Figure 6.4. Place a pressure ring on the disc. (See Figure 7)
Figure 7.5. Place an axle bevel gear so that the outer toothing engages with the toothing of the inner discs. (See Figure 8).
Figure 8.6. Slide two differential bevel gears onto each differential axle. Place axles crosswise into the notches of the pressure ring. (See Figure 9).
Figure 9.7. Place the second axle bevel gear onto the four differential bevel gears. Install the second pressure ring. (See Figure 10).
Figure 10.8. Install second disc set. (See Figure 11).
Figure 11.9. Install washer face up onto axle bevel gear. (See Figure 12).
Figure 12.10. Mount housing cover to housing. Apply 9S3623 Thread Sealant to the bolts and install. Torque bolts to 180 N m (133 lb ft).
