NOTICE:
•
Ensure that the pipe threads are clean. Apply thread sealant to the plugs and fittings.
Failure to do so may result in oil leaks and equipment damage.

There are several methods you can use to install bearings. The recommended meth-
od is to use an induction heater that heats and demagnetizes the bearings. Bearings
can get hot and can cause physical injury.
1.
Install the bearings:
a) Heat the bearings to 100°C | 212°F in an oil bath or with a bearing heater.
b) Clamp the shaft (210) in a bench vise with the thrust bearing surface extending beyond the
end of the vise. Use soft jaws to protect the shaft surface.
c)
Install the properly-heated thrust bearing (320.52) onto the shaft.
If necessary, position a tube against the inner ring of the bearing and gently tap the tube with a
hammer in order to force the bearing onto the shaft. Hold the outer ring of the bearing in order
to prevent vibration damage to the bearing.
d) Apply Thread-EZE to the bearing locknut threads on the shaft.
e) Thread the bearing locknut (923.51) onto the thrust end of the shaft.
The bearing nut is right-hand threaded and is self-locking. It can be reused up to five times, if
handled properly.
f)
Allow the bearing to cool for 10 minutes and retighten.

2.
Install the shaft assembly into the bearing frame:
a) Coat the outside of the bearings with oil.
b) Coat all the internal surfaces of the bearing frame (330) with oil.
c)
Turn the bearing frame (330) vertically with the larger open end pointing up.
d) Install the shaft assembly into the bearing frame (330). Make sure that the shaft rotates
freely.

e) Slide the snap ring (932.51) onto the shaft. Use the designated snap ring pliers to com-
press the snap ring and place it into the locking groove in the bearing frame (330). Make
sure that the snap ring is properly seated in the groove by pressing on the snap ring with a
flat head screwdriver.
