Bearing Adjustment. Mount dial indicator from housing (38, fig. 6-1) to low-speed shaft (11) to check end play. The
angle drive gear box uses roller bearings which do not require adjustment However, when gear box is disassembled for
replacement of parts, bearings require axial end play adjustment to the value shown in table 6-1. If axial end play of shaft
exceeds this value, remove equal thickness of shims from each bearing retainer, thus adjusting bearings.
NOTE
Excessive end play may result from worn bearings. If rollers and raceways have a dull
appearance, replace bearings. Clean and flush reducer and install clean oil.
