Clearance between Hypoid Pinion Shaft and 29T Gear
1. Measure the 29T gear I.D. (1) and hypoid pinion O.D. (2).
2. Calculate the clearance.
3. If the clearance exceeds the allowable limit, replace.
W1027208
Clearance between Hypoid Pinion Shaft and 13T Gear
1. Measure the 13T gear I.D. (3) and hypoid pinion O.D. (4).
2. Calculate the clearance.
3. If the clearance exceeds the allowable limit, replace.
W1027432
Backlash between Differential Pinion and Differential Side Gear
1. Set a dial indicator (lever type) on the tooth of differential pinion.
2. Hold the differential side gear and move the differential pinion to
measure the backlash.
3. If the measurement exceeds the allowable limit, adjust with the
differential side gear shim.
(Reference)
• Thickness of differential side gear shims :
0.8 mm (0.031 in.) 1.2 mm (0.047 in.)
1.0 mm (0.039 in.)
