5.8.2 TRANSMISSION OIL REPLACEMENT
It is required to replace transmission oil within the regulated oil change cycle. And the replacement
procedures are as follows:
1. Park the machine on the flat space, and set the speed shifting handle in neutral gear shift, pull the
button of braking for parking, and put on a fixed frame rod, to prevent the car from moving and
rotating.
2. Start the engine and run it at idle speed, when the engine oil temperature reaches its operating
temperature (about 80
℃
~ 90
℃
), the engine turns off.
3. Drain out the oil by unscrewing the oil outlet screw piston at the bottom of the gear box.
As the oil is still at a higher temperature, therefore it requires wearing protective equipment, and
careful operation, so as to avoid personal injury.
4. Drain out the oil by unscrewing the oil outlet screw piston at the bottom of the gear box and
receive the oil with the container, and then unscrew the air outlet screw piston at the top of the
heat radiators of the torque converter to accelerate oil discharging rate.
5. In the process of replacing transmission oil, it is necessary to replace the fine filter of the gearbox
as well.
6. Remove the transmission oil pan. Clean the filter screen with compressed air or diesel fuel.
7. Install transmission oil pan, oil outlet screw piston and oil outlet screw piston at the lower part of
the torque converter and the corresponding seals.
8. Refuel the clean transmission oil from the oil filling pipe of the gearbox, and inspect the oil level of
gearbox according to the above method, and fill to the regulated oil level.
9.
Before replacing transmission oil, cover the parking brake well to prevent the friction plate of
parking brake from oil and reduce the brake performance.
5.9MAINTENANCE OF DRIVE AXLE OIL
5.9.1 INSPECT OIL LEVEL OF DRIVE AXLE
Inspect the oil level of the gearbox according to the regulated cycle.
Too high or too low oil level of drive axle will result in damages to drive axle, and keep the oil level of
the drive axle in the correct position.
Drive axle fueling and oil level judging criteria:
