Backlash and Tooth Contact between Spiral Bevel Gear and
Spiral Bevel Pinion Shaft
1. Set the dial indicator (lever type) with its finger on the tooth
surface.
2. Measure the backlash by fixing the spiral bevel pinion shaft (3)
and moving the spiral bevel gear (4) by hand.
3. When the backlash is too large, decrease the number of shims
(5) in the side of the spiral bevel gear, and insert the shims (6) of
the same thickness as the removed ones to the opposite side.
When the backlash is too small, do the opposite way of exceed
backlash.
4. Adjust the backlash properly by repeating the above procedure.
5. Apply red lead lightly over several teeth at three positions equally
spaced on the spiral bevel gear.
6. Turn the spiral bevel pinion shaft, while pressing a wooden piece
against the periphery on the spiral bevel gear.
7. Check the tooth contact. If not proper, adjust according to the
instructions next page.

More than 35 % red lead contact area on the gear tooth surface.
The center of tooth contact at 1/3 of the entire width from the
small end.

Replace the adjusting shim (2) with thicker one to move the spiral
bevel pinion shaft backward.
For move the spiral bevel gear rightward, reduce right side shim
(5) and add shim (6) of the same thickness as the right side to left
side.
W10189000
Replace the shim (5) with a thinner one to move the spiral bevel
pinion shaft forward.
For move the spiral bevel gear leftward, reduce left side shim (6)
and add shim (5) of the same thickness as the left side to right side.
Repeat above until the proper tooth contact and backlash are
achieved.
