8.0 INSPECT THE POWER TAKE-OFF COMPONENTS
8.1 Ball Bearings
8.1.1 Visually examine for indications of wear, corrosion, or pitting on balls and races. Apply
clean, lightweight engine oil and slowly rotate the outer race while holding the inner race.
The balls must roll free. Rough or sticking spots must be checked to be sure they are not
particles of dirt. If they are, clean and check again. If not, replace the bearing.
8.2 Tapered Roller Bearings
8.2.1 Visually examine for indications of wear, corrosion, brinelling or pitting on races or
rollers. Rollers must not have flat spots or pitting. Bearing cups and cones must not exhibit
signs of pitting, scuffing or tracking. Lightly oil the races with clean oil, hold one race
stationary while slowly rotating the other race against it. Rough spots or sticking indicate a
need for replacement. Races must be smooth and unworn.
8.3 Bell Housing
8.3.1 Check the bearing fit. Bearing races usually are designed with a sliding or slightly snug
fit in the housing bore. They should not have side movement in the bore. Labyrinth seal
bores at the output end of the bearing housing should be round, not worn oval and should
be approximately ,020”-.025 (.508 mm.-.635 mm.) diameter larger than the drive shaft.
