Front Bevel Gears
Front Bevel Gear Adjustment
When any of the backlash-related parts are replaced, or
the driven gear bolt is loosened; even if the purpose is
not to replace the parts, be sure to check and adjust the
bearing preload, the bevel gear backlash, and tooth con-
tact by replacing shims.
Install the driven gear assy, and tighten the driven gear
nut to the specified torque.
Torque - Driven Gear Bolt: 120 N·m (12 kgf·m, 89 ft·lb)
Do not install the oil seal, and O-ring, and do not stake
the bolt until the correct bearing preload is obtained.
To start with, choose a shim or collar so that the
bearings are just SNUG with NO play and also with
Any overpreload on the bearings could damage the
Apply a little engine oil to the bearings, and turn the gear
shaft more than 5 turns to allow the bearings to seat.
Measure the bearing preload. Bearing preload is defined
as a force or torque which is needed to start the gear shaft
Preload for Driven Gear Bearing
Using Spring Scale:
4 N (0.3
0.5 kg, 0.6
Using Torque Wrench:
0.9 N·m (0.05
Preload can be measured either with a spring scale or
a beam-type torque wrench. When measured with a
spring scale, the preload is designated by force (N, kg,
lb), and when measured with a torque wrench, it is des-
ignated by torque (N·m, kgf·m, in·lb).
