Replacement

1. Check transmission oil level and fill to level with oil

as required. (Refer to Section 2.6.6, “Transmission,”

for information on transmission lubricants.)

2. Replace transmission filter.

3. Check torque on drive shaft yoke retaining bolts.

Torque to appropriate specifications.

4. Refer to the ZF 4 WG-92/98 TSC Transmission

Repair Manual (ZF part number 5871 134 002, JLG

part number 8990495) for servicing the transmission

possible, remove transmission lines from the vehicle

for cleaning.

8. Thoroughly clean transmission filter screens and

cases, and replace transmission filter elements.

opening until oil comes up to the FULL mark on the

engine running at idle.

13. Add oil as necessary to bring the fluid level up to the

FULL mark on the transmission dipstick. Install the

oil dipstick. Recheck the oil level when it reaches

operating temperature 176 - 212° F (80 - 100° C).

14. Recheck all drain plugs, lines, connections, etc., for

leaks and tighten where necessary.

functions through their full range of motion several

times.

2.12.10 After Axle Service

1. Check fluid levels.

2. Check torque on drive shaft flange yoke retaining

bolts. Tighten all fasteners to the appropriate torque,

as specified by the manufacturer.

3. Be sure the lockwashers are properly positioned

under each wheel nut.

4. Check wheel nut torque. Tighten to 430-470 lb-ft

(583-637 Nm).

5. Check toe-in if required.

6. Apply grease at all lubrication points (grease fittings).

7. Refer to the axle manufacturer’s maintenance

manual for further information.
