3A-26 Drive Chain / Drive Train / Drive Shaft:
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
Final gear case bolt (M8) (a): 23 N·m (2.3 kgf-m,
16.5 lbf-ft)
Final gear case bolt (M10) (b): 50 N·m (5.0 kgf-m,
36.0 lbf-ft)
• Using a socket and handle on the final drive bevel
gear coupling nut, rotate the final drive bevel gear
several turns in each direction, while loading the final
driven bevel gear. This will provide a contact pattern
on the coated teeth of the driven bevel gear.
• Remove the final gear bearing case and final driven
bevel gear, and inspect the coated teeth of the driven
bevel gear. The contact patch should be as shown in
the figure of contact position:
• If the tooth contact pattern is incorrect, as shown in
[A], a thinner shim (4) is needed between the final
drive bevel gear bearing and final gear case.
• If the tooth contact pattern is incorrect, as shown in
[C], a thicker shim (4) is needed between the final
drive bevel gear bearing and final gear case.
