BENDIX TU-FLO 400-500-1000 AIR COMPRESSOR Installation, Scheduled Maintenance, Tabulated Data

MAINTENANCE INSTRUCTIONS FOR LARGE SUMP TU-FLO®1000 AIR COMPRESSOR 288578 (SPECIAL APPLICATION)

This compressor is an air-cooled, belt driven, self lubricated, V-four cylinder compressor. It is driven by an electric motor and cooling air is supplied by a fan on the driven pulley. The system air pressure is controlled between 135 psi and 150 psi by a pressure switch starting and stopping the electric motor.

INSTALLATION

The base mounted compressor should be securely bolted down with 1/2" grade five or better cap screws torqued to 70 ft. pounds, making sure that motor and compressor pulleys are aligned and belt tension is correct. The crankcase should be filled with five quarts (4.7 liter) of SAE 20 W engine oil. The compressor must always be installed to rotate clockwise when viewed from the pulley end. The oil pump will not function if rotation is not correct.

SCHEDULED MAINTENANCE

NOTE: When checking or adding oil or servicing the crankcase breather, care should be taken to prevent dirt or foreign material from entering the breather or oil sump.

Every 7,500 miles or seven weeks, whichever occurs first: Check oil level - replenish to top of filler plug opening. Replace both air cleaner filter elements and clean covers. Check belts and replace if broken, damaged or missing.

Every 15,000 miles or 14 weeks, whichever occurs first: Remove crankcase ventilator, clean ports and replace with freshly oiled curled hair.

Every 22,500 miles or 21 weeks, whichever occurs first: Drain oil and refill with fresh SAE 20 W engine oil. Inspect all bolts, fittings and plugs to ensure that all are tight.
