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

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.
