Ingersoll Rand Compressor SSR-HXP20

Warning: This procedure requires trained personnel with PPE!

Improper lubrication can be a cause of motor bearing failure. The quantity of grease added should be carefully controlled.

The smaller motors must be greased with a lesser amount of grease than larger motors.

When regreasing, stop motor. Disconnect power; lock out and tag.

Outlet plugs (or spring-loaded grease relief plugs if present) removed?

The outlet plug may not be accessible on the fan end of some TEFC motors.

Grease relief along shaft can occur, precluding necessity of removing this plug if inaccessible.

The inlet grease gun fittings and outlet plugs (or spring-loaded reliefs) are located at each end of the motor housing.

The drive end reliefs protrude out the circumference of the lower portion of the end bell near a flange bolt.

Warning: This procedure requires trained personnel with PPE!
