Gear Backlash Adjustment
Step 11 Gear backlash adjustment is accomplished by moving shims from front to back gear side or vise
versa. To increase backlash move.012” thick shim from back to front side of gear. Note: Front side of gear is
face toward center of gear box. If.012” shim is not present but a.020” shim is replace the.020” shim with
two.012” Shims and then make adjustment. To decrease backlash move Shims the opposite direction.
Once this adjustment has been made, remove the Cap and Gaskets. Install all Gaskets on Cap and then apply
a small bead of sealant around flange of the Cap and on top of the Gaskets. Reinstall the Cap on the housing
and install all eight Bolts and tighten them to a torque of 31 to 34 foot pounds. Figure Mnt-R-0134.
