7.7.4 After Transmission Service or
Replacement
Refer to the ZF 4 WG-98 TS Transmission Repair Manual
(ZF part number 5871 139 002, JLG part number
8990418) for information on servicing the transmission
after overhaul or repair. In general:
1. Check transmission oil level and add oil as required.
2. Install a new transmission filter (1).
3. Check the torque on the drive shaft yoke capscrews.
4. Wear suitable eye protection. When an overhauled
or repaired transmission is installed, thoroughly
clean the oil cooler lines to and from the transmission.
5. Drain and flush the entire system.
6. Disconnect and clean all transmission cooler hoses.
When possible, remove transmission lines from the
vehicle for cleaning.
7. Thoroughly clean transmission filter screens and
cases, and replace transmission filter elements.
CAUTION:
(39.6 bar) when back flushing the oil cooler.
Applying too much pressure may damage the
oil cooler/radiator.
8. Back flush the transmission oil cooler portion of the
radiator with oil and compressed air until all foreign
material is removed. Flushing in the direction of
normal oil flow does not adequately clean the cooler.
If needed, remove the radiator from the vehicle.
IMPORTANT: DO NOT use flushing compounds for
cleaning purposes.
9. Reassemble all components and fill the transmission
with clean recommended oil through the dipstick
tube opening (2). Remove the dipstick and fill with
approximately 12 quarts (11,4 liters) of
recommended oil. Check the level by taking
intermittent dipstick readings as outlined in Section
2.13.10, a. Transmission Oil Level Check . DO NOT
overfill. Reinstall the dipstick when finished.

10. Run the engine for two minutes at idle (1,000-1,100 rpm)
to help prime the torque converter and the
transmission oil lines.
11. Recheck the level of the oil in the transmission with
the engine running at idle (1,000-1,100 rpm).
12. Add recommended oil as necessary to bring the fluid
level up until it reaches the FULL mark on the
dipstick. Recheck the oil level when it reaches
operating temperature (180-200° F or 83-94° C).
13. Recheck all drain plugs, lines, connections, etc., for
leaks and tighten where necessary.

TOWING A DISABLED VEHICLE

Towing a disabled vehicle should only be attempted as a
last resort, after exhausting all other options. Make every
effort to repair the vehicle, and move it under its own pow-
er, before using the emergency towing procedures out-
lined in either Section 2.14.1, Towing a Disabled Vehicle
Short Distances or Section 2.14.2, Towing a Disabled Ve-
hicle Long Distances .
IMPORTANT: After the vehicle has been towed to a
secure location, reactivate the parking brake. Carefully
follow the procedures from start to finish. Consult your
local JLG Authorized Service Center (ASC) or the JLG
Service Department if you are unsure about any part of
the procedure, or for specific instructions for your partic-
ular situation.
