Adjustment of the Differential

^ If it is necessary to replace the cam gear, the right hand side gear, or the reaction blocks, the entire differential must be adjusted. The differential is adjusted using selective thickness thrust washers behind each side gear, and selective thickness thrust washers between the reaction blocks.
^ It is important to build up the differential properly. The proper clearance between parts is critical to the operation of the unit.
^ There are three adjustments needed:
(1) Left side gear backlash.
(2) Right side gear backlash.
(3) Thrust block clearance.
