Step 8 Install shims if they were present at disassembly against back side gear. Total thickness for shims used
on front and back side of input gear is.040.” Another method to determine amount of shims to place against
back side is to measure thickness of shims on opposite side of gear and subtract total from.040. Never use
shim less than.012 thick.
Step 9 Install Input Cap on Shaft and Housing and check the gap between Cap and Housing to see what the
approximate thickness of Gaskets will be required. Figure Mnt-R-0133. Remove the Cap and install the
Gaskets. Reinstall the Cap and Gaskets on Housing. Install four Bolts and tighten them. Note: These four Bolts
should be installed in every other Bolt Hole of the Cap, and when tightening, the second Bolt tightened should
be 180 degree away from the first Bolt tightened. Check to see how the Input Shaft turns. If it is tight, then
additional Gaskets need to be added. If it turns very loose and the Shaft can be moved in or out of the cap,
then Gaskets need to be removed. The correct adjustment of the Input Shaft Bearing is when the Shaft turns
freely but cannot be moved in or out of the Housing.
Check Gear Backlash
Step 10 Hold output shaft with one hand and grab input shaft with other hand. Rotate shaft back and forth to
feel space (backlash) between gears. There must always be rotational space (backlash) between the gears. If
space (backlash) does not exist or is too large proceed to step 11 for adjustment.
