Inspection of bearings
Rotate each bearing to check for rotation. Replace a
bearing which fails to rotate smoothly. Check the fit of
the bearings on the drive shaft and idler shaft. Re-
place the shaft or bearings whichever are badly worn.
Check the fit of bearings in the drive case and replace
a worn part.
