External Wiring
Starting and overload control devices must be matched
to motor rating. For safety or convenience they may
need to be installed some distance from the motor

Inspection
Antifriction Bearing
1.Remove the parting bolts at the horizontal split
Remove the bolts at the outer circumference of the upper half of the
3.Pull the upper bracket away from the face of the frame and remove bracket
Sleeve Bearing - 1120 Frames
3.Air deflectors on sleeve bearing motors are horizontally split
Vibration
Most problems can be detected when inspected visually. Check for;
2.Accumulation of dirt on fan or rotor

Oil Seals
The primary purposes of the oil seal are:
1.To prevent the entrance of dirt into the bearing cavity
2.To retain the oil in the bearing cavity
3.To provide pressure regulation in the bearing cavity
Sealing Parts
Apply sealant as follows:
Surfaces shall be clean of dirt, grease, and oil sealant. Use a
gap when mating surfaces are together
4. Assemble parts
1.Ring out of round (should be round to 0.062 inch)
2.Fouling on a projection of the bearing bushing
5.Oil too cold or viscous, or oil level too high
6.Shaft not level – oil ring tends to bind
