Backlash and Tooth Contact Between Spiral
Bevel Gear and Spiral Bevel Pinion
1. Set a dial gauge (lever type) with its finger on the
tooth surface of spiral bevel gear.
2. Measure the backlash by fixing the spiral bevel pin-
ion (1) and moving spiral bevel gear (3) by hand.
3. If the backlash exceeds the factory specifications,
decrease the number of shims (4) and insert the re-
moved shims to the differential support (6). If the back-
lash is less than the factory specification, decrease
the number of shims (5) at differential support (6) and
insert the removed shims to the opposite side.
4. Adjust the backlash properly by repeating the proce-
dures.

Spiral Bevel Pinion Turning Torque (With
Differential Gear)
1. Grip the spiral bevel pinion nut (1) with a torque
wrench (2) and measure the turning torque.
2. If the turning torque is not within the factory specifi-
cations, check the differential gear turning force,
backlash and tooth contact again.

Side Clearance Between Synchronizer Ring
and Gear (In Contact)
1. Press the synchronizer ring against the tapered
portion of the gear, and measure the side clearance.
2. Apply thin film of red lead to the tapered portion,
press the ring against it by hand, rub them together
a few times, and check the contact.
3. Check the tooth surface and key grooves of the ring
for wear.
4. If the side clearance exceeds the allowable limit or
if there is any defect, replace the synchronizer ring.
