Maintenance
d) Carefully guide the shaft and bearing assembly into the bearing frame until the thrust
bearing is seated against the shoulder of the frame. Make sure that the oil rings do not
bind or become damaged.
Do not force the assembly together.
e) Observe the oil rings through the sight glass in the bearing frame.
If the oil rings are not properly seated in the grooves in the shaft, insert a hook-shaped
tool made from wire through the inspection connections. Reposition the oil rings as
necessary to seat them in the grooves.
f) Check that the shaft turns freely.
If you notice rubbing or binding, determine the cause and correct it.
7. Replace the oil-ring inspection connection plugs.
8. Replace the two oil-ring retainers.
The screw should bottom against the bearing frame.
Assemble the frame
CAUTION:
• Failure to align the gasket with oil grooves will result in bearing failure from a lack of lubrication.
• Do not over-tighten the thrust-bearing end-cover and bearing-frame screws.
• Do not allow the dial indicator to contact the keyway when turning the shaft. Readings will be
incorrect and damage to dial indicator could result.
• For runout checks, firmly support the bearing-frame assembly in the horizontal position.
