General Information, Specifications and Maintenance
2.12.6 After Transmission Service or
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
after overhaul or repair.
5. Wear suitable eye protection. When an overhauled
or repaired transmission is installed, thoroughly
clean the oil cooler lines to and from the
transmission.
6. Drain and flush the entire system.
7. Disconnect and clean all transmission lines. When
possible, remove transmission lines from the vehicle
for cleaning.
8. Thoroughly clean transmission filter screens and
cases, and replace transmission filter elements.
9. “Back flush” the transmission oil cooler with oil and
compressed air until all foreign material is removed.
Flushing in direction of normal oil flow does not
adequately clean the cooler. If needed, remove the
transmission oil cooler assembly from the vehicle.
DO NOT use flushing compounds for cleaning
purposes.
10. Reassemble all components and fill the transmission
with clean, fresh oil through the dipstick tube
opening until oil comes up to the FULL mark on the
transmission dipstick.
11. Run engine for two minutes, at idle, to help prime the
torque converter and transmission lines.
12. Recheck the level of fluid in the transmission with 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.
2.12.7 After Tire and Wheel Service
1. Check air pressure.
2. Check wheel nut torque. Tighten to 430-470 lb-ft
(583-637 Nm).
2.12.8 After Engine Service
Consult the qualified service agent (manufacturer’s
representative and/or service manual) for proper
procedures before engine startup.
2.12.9 After Boom Service
1. Check wear pads.
2. Check chain tension adjustment.
3. Apply grease at all lubrication points (grease fittings).
4. Check for proper operation by operating all boom
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.
CAUTION:
DO NOT exceed 165 psi
(11,4 bar) when back flushing the oil cooler.
Applying too much pressure may damage the
oil cooler/radiator.
