Remove Differential And Carrier Assembly
1. Remove the lower drive shaft and the crankcase guard. Drain the oil from the differential and both final drive compartments.2. Remove the final drive covers, and move each axle out approximately 30.5 cm (12 in.). 3. Install tooling (A) under the axle housing, and lift the machine approximately 101.6 mm (4 in.).4. Install tooling (B) under the frame of the vehicle. 5. Disconnect brake tube assemblies (2) and (3) from above the axle housing on the right and left hand sides of the axle housing. 6. Remove four nuts (1) closest to the differential from the four studs that fasten the axle housing to the frame. See photo B91721X1 on Page 99.7. Use a 19.1 mm (.75 in.) diameter steel rod to make four 304.8 mm (12.00 in.) long guide pins. Put 3/4"-16 NF threads on one end of the guide pins.8. Make a replacement of the four inner bolts that hold the axle housing to the frame with the fabricated guide bolts (5) as shown.9. Remove the remainder of the nuts from the studs, and lower the axle housing from the vehicle with tooling (A).10. Disconnect hose assembly (4) from the carrier housing. 11. Remove all but the top two bolts (6) that hold the differential in the axle housing.12. Put a transmission jack in position under differential (7). Fasten the differential to the transmission jack. 13. Install two 3/8"-16 NC forcing screws (8), and remove the two bolts and the differential (7) from the axle housing. The weight of the differential is 204 kg (450 lb.).Install Differential And Carrier Assembly
1. Fasten differential (1) to the transmission jack. 2. Install the differential in the axle housing with the transmission jack. Tighten bolts (4) to a torque of 265 25 N m (195 18 lb.ft.).3. Connect hose assembly (2) to the carrier housing. Remove the transmission jack. 4. Install tooling (A) under the axle housing. Lift the machine, and remove tooling (B) from under the machine frame.5. Lower the machine and remove tooling (A).6. Remove fabricated guide bolts (3), and install the original bolts and nuts. 7. Install brake tube assemblies (5) and (6).
