a.
Power Take-off. Wash all parts of the power take-off, except the clutch facings, in clean fuel oil or a good
solvent, then blow dry before inspection.
NOTE
Tough or sticking spots of the bearings are cause to reject the bearings from further use.
1.
Bearings. Examine cups, races, balls, and rollers for indications of corrosion or pitting. Apply light engine
oil to the bearings; then, while holding the inner race, slowly revolve the bearing and outer race to check
for free rolling of the balls or rollers on the races and cups. Power take-off with ball-type shaft bearings do
not require bearing adjustment. The approved method for field adjustment of tapered roller bearings in the
power takeoff unit is by use of a dial indicator to measure actual shaft end play. Adjust tapered roller
bearings as follows:
a)
Remove the housing hand hole plate and the retainer lock.
b)
Tighten retainer to firmly seat both bearings. Mark notch for reference.
c)
Back off bearing retainer three of four notches.
d)
Tap output end of shaft with soft hammer to seat bearing cup against bearing retainer. This should
be the approximate end play required.
e)
Measure actual end play with a dial indicator.
f)
Indicator readings should be taken with the indicator anchored to the housing and the indicator tip
resting on the end of the shaft. Firmly hold housing and pry shaft axially in and out to get indicator
reading.
g)
Adjust bearing retainer until measured end play is within limits.
h)
Lock bearing retainer.
2.
Clutch Facings. Examine the clutch facings for being scored, burned or cracked; inspect driving teeth for wear or
damage and measure thickness of the facings. Replace any clutch facing that is badly scarred, burned, or has
driving teeth that are worn and/or damaged, or if the facing thickness is worn to under 5/16-inch.
