4.4 BACKLASH OF 8 BEVEL PINION SHAFT AND 34 BEVEL GEAR
Set the lever type dial indicator so that it contacts
with the spline of the 8 spiral bevel pinion shaft as
shown in the fi gure.
Measure the backlash by moving the 8 bevel pinion
shaft by hand lightly.
Teeth based Backlash : 0.2 ~ 0.3 mm
(0.008 ~ 0.012 in.)
Spline based Backlash : 0.08 ~ 0.12 mm
(0.0031 ~ 0.0047 in.)

4. Replace the collars (4) and (5) installed to the front
and rear sides of the shaft if the 8 spiral bevel pin-
ion shaft (6) should be moved. However, the total
thickness of the front and rear collars should be
22.75 mm (0.8957 in.).
Size of adjusting collar : 4.55 mm (0.1791 in.)
4.65 mm (0.1831 in)
4.75 mm (0.1870 in.)
4.85 mm (0.1909 in.)
4.95 mm (0.1949 in.)
17.8 mm (0.7008 in.)
17.9 mm (0.7047 in.)
18.0 mm (0.7087 in.)
18.1 mm (0.7126 in.)
18.2 mm (0.7165 in.)
5. Measure the contact area if the shim or collar has
been adjusted.
This procedure can be skipped if it is not necessary
to adjust the shim.
3. Adjust the shims (2) and (3) if the 34 spiral bevel
gear (1) should be moved to adjust the backlash.
Size of shim : 0.1 mm (0.0039 in.)
0.2 mm (0.0079 in.)
0.4 mm (0.0157 in.)
0.8 mm (0.0315 in.)
1.0 mm (0.0394 in.)
1.2 mm (0.0472 in.)

The standard backlash stated in the previous
page refers to the distance from the mating
surface of the gear teeth. Therefore, the standard
backlash value can differ if the backlash is
measured at the splined section of the pinion
shaft.
As the average effective diameter A of the spiral
bevel pinion teeth is different from the effective
diameter B of the splined section as shown in
the figure on the previous page, the backlash
on the spline can be obtained from the following
formula:
Backlash measured at splined section
= Teeth based backlash
Therefore the spline based backlash is
0.2 x 0.4 ~0.3 x 0.4 = 0.08 ~ 0.12 mm
(0.0031 ~ 0.0047 in.)
