• Proper Contact
More than 35 % red lead contact area on the gear tooth surface.
The center of tooth contact at 1/3 of the entire width from the
small end.
• Shallow or Heel Contact
Change the combination of adjusting collar 1 (6) and 2 (7) with
thicker one to move the spiral bevel pinion shaft backward.
Check the clearance between 33T G-PTO gear (2) and external
circlip (8), if the measurement is bigger than factory specification,
change the collar 2 (7) to become the clearance is within the factory
specification.
And reduce the shim (4) to move the spiral bevel gear rightward.
Repeat above until the proper tooth contact and backlash are
achieved.
• Deep or Toe Contact
Change the combination of adjusting collar 1 (6) and 2 (7) with
a thinner one to move the spiral bevel pinon shaft forward.
And increase the shim (4) to move the spiral bevel gear
leftward.
Repeat above until the proper tooth contact and backlash are
achieved.
