15. Check the teeth engagement between the axle driven
bevel gears:
(a) Coat three or four teeth at three different positions of the
axle driven bevel gear in red
(b) Hold the flange tightly while rotating the axle driven
bevel gear.
(c) Check the teeth engagement situation.
Remark: the trace of the teeth of axle driven bevel gear should
satisfy this requirement. Otherwise, select the suitable adjust-
ing washer for correcting according to the situation of poor
teeth engagement;
Select the adjusting gasket that makes the main teeth apart
from the axle driven bevel gear.

20. Mount the front speed reducer shell assembly:
(a) Clear the front speed reducer shell and the contact face of
front speed reducer shell;
(b) Coat the glue line with diameter of 2-3 mm, and the glue
line should be even and without fracture.
Remark: The front speed reducer shell should be mounted
ready within 15 min after coating the glue.
