tool.
5. Check the swing difference of the axle driven bevel gear;
Run the flange to measure the axle driven bevel gear with the
dial-indicating lamp.
Swing difference)
0.07mm
Max swing difference: 0.07 mm
In case the swing difference is more than 0.07 mm, change the
compete package of driven bevel gear.

6. Check the teeth-clearance of the driving bevel gear and
the axle driven bevel gear:
(a) Install the dial-indicating lamp and ensure the axial line
of measuring head is vertical with the contact teeth face.
(b) Run the flanges, and record the clearance values of
driving bevel gear and the axle driven bevel gear.
Specified clearance range
(0.15-0.25)mm
Remark: the inspection should be conducted at no less than
three equally divided spots on the circumference of the axle
driven bevel gear.
7. Check the engagement trace of the axle driven bevel
gear.
(See page SA-76)
8. Tear down the flange and dust cover:
(a) Loosen the riveted position of main-tooth nut with the
hammer and chisel.
