Ingersoll Rand Compressor SSR-XP75

Tools Required: Open end wrench, Pliers

The screen/orifice assemblies are similar in appearance to a straight tubing connector and will be located between two pieces of 1/4 inch O.D. scavenge line tubing.

The main body is made from 1/2 inch hexagon shaped steel and the diameter of the orifice and a direction-of-flow arrow is stamped in flat areas of the hexagon.

A removable screen and orifice is located in the exit end of the assembly and will require cleaning.

To remove the screen/orifice, disconnect the scavenge line tubing from each end. Hold the center section firmly and use a pair of pliers to gently grasp the exit end of the assembly that seals against the scavenge line tubing.

Pull the end out of the center section while using care to prevent damage to the screen or sealing surfaces.

Clean and inspect all parts prior to reinstallation.

When the assembly is installed, confirm the direction of flow to be correct. Observe the small arrow stamped in the center section and ensure the direction flow to be from the separator tank to the airend.

Warning: This procedure should be performed in a clean environment and requires trained personnel with PPE!

Is the operating environment extremely dirty?

If yes, change coolant, filters, and separator elements more frequently.

Has the coolant filter been changed in the last 150 hours of operation?

If no, proceed to change the coolant filter.

Is a suitable device available for loosening the old element?

If no, acquire a suitable device before proceeding.

Is a drain pan available to catch any leakage during removal?

If no, acquire a drain pan before proceeding.

Warning: This procedure requires trained personnel with PPE!

All 60 Hz ODP drive motors and all fan 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.

The drive end outlet plugs are located just behind the flange in the air intake area at about the 5 or 6 o’clock position.

Free drain hole of any hard grease (use piece of wire if necessary).

Use a hand lever type grease gun.

Determine in advance the quantity of grease delivered with each stroke of the lever.

Clean cooler cores if discharge air temperature is excessive or if unit shutdown occurs on high air temperature.

Ensure that the compressor is isolated from the compressed air system by closing the isolation valve and venting pressure from the drip leg.

Ensure that the main power disconnect switch is locked open and tagged.

■ Air hose equipped with approved O.S.H.A. nozzle.

On units sold outside the U.S.A. consult local codes.

Use a hand lever type grease gun. Determine in advance the quantity of grease delivered with each stroke of the lever. A graduated cylinder showing cubic centimeters (cc) may be used, or a 35mm film canister can give a close approximation for 2 cubic inches when filled.

Add the recommended volume of the recommended lubricant. Do not expect grease to appear at the outlet, but if it does, discontinue greasing at once.

Run motor for about 30 minutes before replacing outlet plugs or reliefs. BE SURE TO SHUT MOTOR DOWN, DISCONNECT POWER, LOCK OUT AND TAG, AND REPLACE THESE DRAIN FITTINGS TO PRECLUDE LOSS OF NEW GREASE AND ENTRANCE OF CONTAMINANTS!
