3A-26 Drive Chain / Drive Train / Drive Shaft:
Backlash is too small
• Install a thicker shim pack (1) between the final driven
bevel gear and final gear case.
• Decrease thickness of the shims (2) between the final
driven gear bearing and bearing case by an amount
equal to increase above.
List of shims (1)
List of shims (2)
EXAMPLE:
Final gear to case shims (1);
1.45 mm + 1.40 mm = 2.85 mm
Final gear bearing to bearing case shims (2),
0.35 mm + 0.60 mm = 0.95 mm
Original total measurement (1) + (2) = 3.80 mm
Backlash too large:
Final gear to case shims (1);
1.35 mm + 1.45 mm = 2.80 mm
Final gear bearing to bearing case shims (2),
0.60 mm + 0.40 mm = 1.00 mm
Total thickness (1) + (2) = 3.80 mm
Backlash too small
Final gear to case shims (1);
1.50 mm + 1.40 mm = 2.90 mm
Final gear bearing to bearing case shims (2);
0.50 mm + 0.40 mm = 0.90 mm
Total thickness (1) + (2) = 3.80 mm
Tooth Contact
After backlash adjustment is carried out, the tooth
contact must be checked.
• Remove the case. Do not misplace the shims.
Remove the final driven bevel gear.
• Clean and degrease several teeth on the final driven
bevel gear. Coat these teeth with machinist’s dye or
paste, preferably of a light color.
• Reinstall the final driven bevel gear with shims in
place, positioning the coated teeth so that they are
centered on the final drive bevel gear.
• Reinstall the final gear bearing case and bolts, and
tighten to specification.
Tightening torque

16.5 lb-ft)
Final gear case bolt (M10) (b): 50 N·m (5.0 kgf-m,
36.0 lb-ft)
