STEP 7
Install the Shaft Assembly into the Main Housing. FIGURE 49. Install the Input Cap and check the gap between the
Main Housing and the Input cap to determine the approximate amount of Shims that will be required. Remove the
Input Cap and install the Gaskets. Reinstall the Cap and install four Bolts. FIGURE 50.
NOTE! These four Bolts should be installed in every other bolt hole of the Cap When tightening, the second bolt
tightened should be 180 degrees away from the first bolt tightened. Check how the Input Shaft turns. When
turned, if tight, additional Shims are needed. If loose and the Shaft can be moved from side to side, Shims need
to be removed. The correct adjustment of the Input Shaft Bearings is when the Shaft turns freely, but cannot be
moved from side to side in the Housing.
