Adjusting Backlash
Backlash specification 0.25 ∼ 0.35 mm
(0.010 ∼ 0.014 in.)
Adjust shim thickness (between bearing housing of axle
housing (A) and bearing) to get specified backlash.
Shim stock for this adjustment is available in these
thicknesses:
Thickness Part No.
Shim set 77-4000
0.1 mm (0.004 in.) 76-7290
0.2 mm (0.008 in.) 76-7300
0.4 mm (0.016 in.) 76-7310
Shim Between Differential and Axle Housing (B)
After obtaining specified backlash, determine amount of
s
hims needed:
1. Put the straightedge flat on the ball bearing (Fig. 28A).
2. Read clearance A between axle housing (A) and
s
traightedge.
3. Put straightedge on axle housing (B) and read clear-
ances
C and D. Subtract D from C. The difference
between D and C is clearance B (Fig. 28B).
Figure 27
4. Select from the shim shock to obtain:
