8.12.6.1.Adjustment of toe-in
Adjustment method is the same to relevant contents of two wheel drive front axle assembly
8.12.6.2.Structure and adjustment of front drive axle assembly
The power of front drive is transmitted to the front central drive via transmission shaft by the transfer case. The
front central drive will distribute power to semi-axle on two sides. Then, power will be transmitted to front and rear
drives so that front driving wheel is rotating.
In the process of field operation, especially under situation that paddy filed operation condition is relatively severe,
muddy water will easily enter into end faces of front and rear linings to damage end faces and increase axial
movement. Normal axial movement can be maintained by adjusting M16 bolt in the front of the front supporting
seat.
●
Adjustment of central drive part:
After two bearings on driving gear of the front central drive has been used for certain period, axial displacement
will be increased. Therefore, small round nut will be tightened to reduce axial displacement of the bearing. When
adjusting, the bearing cannot have load. Small round nut will be tightened. Then, (1/25-1/15) ring will be returned.
At last, small round nut will be tightened. Manually rotate and input bevel gear shaft that shall be rotated flexibly.
Gear back lash of bevel gear pair of front central drive and mesh imprint will obtain good mesh imprint by increasing
or reducing adjusting pad (contact spot: it is not less than 50% along the direction of height of tooth and it is not
less than 50% along the direction of length of tooth. In addition, it need be slightly close to little end) and suitable
gear back lash (0.2-0.4) mm. Adjustment method is the same to adjustment method of contact imprint of central
bevel gear pair and gear backlash. When the back lash between driving gear of front central drive and driven gear
is enlarged, it can become normal by adding adjusting pad on the left side of the front differential mechanism.
Attention: large and small bevel pinions of central drive are supporting bevel pinions, which cannot be assembled
in disorder. When replacing, it shall be replaced in pairs, which shall be replaced together with the bearing,
otherwise, it will affect its lifetime.
●
Adjustment of two pairs of bevel gear pair
Pinions on front and rear drives installed on the main pin and bevel gear and bearing installed on bearing and semi-
axle will generate abrasion after being used for a long term so that the back lash of bevel gear pair will become
bigger. Therefore, it must be adjusted. Adjustment method is as below: loosen purge cock on the lower end of the
central drive, open the sealed cap on the rear drive shell and discharge lubricating oil.
A. After the axle shaft sleeve is separated from final drive casing, adjustment will be conducted in accordance with
