3.17.1.3 Rear axle and brake faults and troubleshooting methods
Table 3-5 Faults and Troubleshooting Methods of Rear Axle and Brake
1. Increased
noise of the
central drive
(1) The bearing clearance of small bevel gear
is too large.
(2) Abnormal gear engagement
(3) The supplementary bearing of bevel gear
or the gear is damaged.
(4) Wear and seizure of differential shaft
(5) Wear in planetary gear or gasket
(6) Wear or damage of differential bearing
(1) Adjust as required.
(2) Readjustment as required
(3) Replace bearing or gear
(4) Replace the differential bearing
(5) Replace the planetary gear or gasket.
(6) Replace the differential bearing
2. Overheating
of driving spiral
small bevel gear
and differential
bearing
(1) The pre-tightening force is too large.
(2) Lubrication is poor.
(3) The backlash of bevel gear pair is too
small.
(1) Readjust the pre-tightening force
(2) Check the lubricating oil level, and
supplement it in case of insufficiency.
(3) Adjust the gear backslash
3. Abnormal
final drive
sound
(1) The bearing, gear or shaft is damaged.
(1) Replace the bearing, gear or shaft.
(1) Free stroke of brake pedal too large
(2) Serious wear or eccentric wear of friction
plate
(3) Free stroke of pedal too large
(1) Readjust the pedal free stroke.
(2) Replacement of friction plate
(3) Adjust the pedal free stroke as required.
(1) The brake friction plate does not return.
(2) The friction plate is not completely
separated from the brake hub
(1) Replace the return spring
(2) Adjust as required.
6. Deviation of
tractor during
braking
(1) The free travels of the left and right brake
pedals are inconsistent.
(2) Damaged brake lining on one side
(3) Inconsistent pressure of two rear tires
(1) Adjustment
(2) Replacement of friction plate
(3) Check and inflate the tires as required.
