Correcting of Tooth Contact
1. Proper contact.
• No adjustment.
2. Correcting of the heel contact and shallow contact.
• Change the bearing holder shim (1) to thick it.
• Repeat above until the proper tooth contact and backlash
are achieved.
3. Correcting of the toe contact and deep contact.
• Change the differential bearing holder shim L (6) to thin it.
• Change the differential bearing holder shim R (5) to thick it.
• Change the bearing holder shim (1) to thin it.
• Repeat above until the proper tooth contact and backlash
are achieved.

Clearance between Mid-PTO Drive Shaft to 15T Gear
1. Measure the 15T gear I.D. (1) and mid-PTO drive shaft O.D. (2).
2. Calculate the clearance.
3. If the clearance exceeds the allowable limit, replace.
