Model 6042 Legacy Origin 7/02

Transmission: ZF 4 WG-98 TC

6.7.4 After Transmission Service or

Replacement

Refer to the ZF 4 WG-98 TC Transmission Repair Manual

(ZF part number 5871 135 002) for information on

servicing the transmission after overhaul or repair. In

general:

1. Check the transmission oil level and add oil as

required.

2. Install a new transmission filter.

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.

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, fresh Universal Tractor Fluid through the

dipstick tube opening (Fig. 6-15, 1). Remove the

dipstick and fill with approximately 3 gallons

(11 liters) of Universal Tractor Fluid. Check the level

by taking intermittent dipstick readings as outlined in

the appropriate Owners/Operators Manual. 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 fluid in the transmission with

the engine running at idle (1,000-1,100 rpm).

12. Add Universal Tractor Fluid 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.

6.8 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

power, before using the emergency towing procedures

outlined in the appropriate Owners/Operators Manual.

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 OmniQuip Authorized Service Center (ASC) or the

OmniQuip Service Department if you are unsure about

any part of the procedure, or for specific instructions for

your particular situation.

CAUTION: DO NOT exceed 165 psi

(39.6 bar) when back flushing the oil cooler.

Applying too much pressure may damage the

oil cooler/radiator.
