3). Visually inspect the oil for contamination and use a magnetic probe to insert it
from the filling hole. Adjust the oil level if necessary.
2. If it is necessary to rise the vehicle axle during other maintenance, the following
inspection items can be carried out in order:
1). Check whether the wheels rotate smoothly;
2). Use the pry bar to reach the bottom of the wheel to move the wheel up and
down. Check whether the bearing is loose or the wheel is with excessive
displacement.
Installation precautions:
1. Clean and wipe the axle shaft tube and apply lubricant slightly;
2. The oil seal ring is pressed into the shaft tube and against the shaft shoulder, and
the o-ring enters the groove formed by the oil seal ring and shaft head;
3. Push the hub assembly directly into the shaft tube by using the spreader, until it
reaches the seat ring;
4. With 400 N. m torque: tighten the locking nut and rotate the hub at the same time.
5. If the lock washer locating hole is not aligned with the lock nut hole, please
continue to tighten the lock nut until it is aligned. It is forbidden to loosen the lock
nut back.
6. Fill the wheel hub with gear oil through the filling holes on the wheel hub cover or
the side wall of the wheel hub, until the indicated scale of oil level (fuel capacity of
steering axle is about 0.5l/single side, and fuel capacity of drive axle is about 1L/
single side).
7. There is no need to check the clearance at the conmet wheel end during
inspection and installation. If you need to check the clearance, please go to the
technical service center (station) authorized by Dongfeng Commercial Vehicle Co.,
Ltd., to check with special equipment. The clearance specification is less than or
