General Information and Specifications
2.30 Model 6042 Legacy Origin 7/02
2.12.3 After Hydraulic Component Service
1. Check the torque of fasteners on replaced
components.
2. Check that the hoses and tubes are properly
attached, properly positioned and that all fittings are
properly tightened.
3. If a hydraulic component failed and contaminated
the system:
• Drain the hydraulic oil reservoir
• Flush the system using clean hydraulic oil
• Prime the pump
• Clean the hydraulic oil reservoir
• Change the hydraulic oil filter
4. After normal hydraulic component maintenance,
check the hydraulic oil level, and add oil as required.
5. Start the engine and purge the hydraulic system of
air. Operate all boom functions through their full
range of motion several times. Cycle the lift and
extend cylinders to purge air from the system.
Visually check for leaks.
6. Check operation of all systems in the hydraulic
circuit by operating the controls through all functions
several times.
2.12.4 After Brake System Service
1. Check the oil level in the axle and replenish with
Universal Tractor Fluid as required.
2. Bleed the air from the brake system.
3. Check the brake pressure.
4. Check the brake operation.
2.12.5 After Fuel System Service
1. Drain and flush fuel tank, if it was contaminated, with
clean fuel.
2. Replace all fuel filters.
3. Fill fuel tank with fresh, clean fuel as required.
4. Bleed the fuel system of air.
2.12.6 After Transmission Service or
Replacement
1. Check transmission oil level and fill to level with
Universal Tractor Fluid as required. (Refer to Section
2.6.3, “Transmission” for information on transmission
lubricants.)
2. Replace transmission filter.
3. Check torque on drive shaft yoke retaining bolts.
• Upper driveshaft 35 lb-ft (47 Nm)
• Lower driveshaft 60 lb-ft (81 Nm)
4. Refer to the ZF 4 WG-98 TC Transmission Repair
Manual, OmniQuip P/N 8990455 (ZF P/N 5871 135
002) 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 transmissions 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 Universal Tractor Fluid
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 Universal Tractor Fluid 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
(180-200° F or 83-94° C).
14. Recheck all drain plugs, lines, connections, etc., for
leaks, and tighten where necessary.
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.
