Ingersoll Rand Compressor SSR-ML37

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. 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.

Inspect Separator element differential

Inspect Air filter Delta P (at full load)

Warning: This procedure requires trained personnel with PPE!

In extremely dirty environments change coolant, filters, and separator elements more frequently.

Is the operating environment extremely dirty?

The coolant filter should be changed after the first 150 hours of operation and every 2000 hours thereafter, or when the coolant is being changed.

Is it time to change the coolant filter?

Use a suitable device and loosen the old element. Use drain pan to catch any leakage during removal. Discard old element.

Was the old element successfully removed?

Wipe the sealing surface of the filter with a clean, lint-free rag to prevent the entry of dirt into the system.

To check condition of separator element, run compressor in full load mode and at rated pressure and select "SEPARATOR PRESSURE DROP" in display table. If display says "XX PSI", then no maintenance is required. If warning light is on and display says "CHG SEPR ELEMENT" then the separator should be replaced.

Loosen the fitting that holds the scavenge tube into the tank and withdraw the tube assembly.

Disconnect blowdown valve from elbow in tank cover.

Disconnect tube from fitting on minimum pressure check valve. Loosen tube nut on same tube at aftercooler inlet then swing tube away from tank cover.

Use a suitable wrench and remove the bolts that hold the tank cover in position. Remove cover by lifting up and away.

Carefully lift the separator element up and out of the tank. Discard the faulty element.

Clean the gasket surface on both the tank and its cover. Exercise care to prevent pieces of the old gasket from falling down into the tank.

Check the tank to be absolutely certain that no foreign objects such as rags or tools have been allowed to fall into the tank. Install replacement element down into the tank after checking the new element gaskets for possible damage. Center the element up within the tank.

Place the tank cover in its correct position and install bolts. Tighten the bolts in a cross-pattern to prevent over-tightening one side of the cover. An improperly tightened cover will likely result in a leak.
