107981 is an air compressor for Caterpillar 3100 Series and Caterpillar C7 engines. It mounts on the engine and pressurizes air for the brake system's reservoir tanks, and it is sold individually as a single unit.
The compressor supplies the air that the brakes and other air-operated systems depend on, so a tired one can leave a truck stranded. Oil showing up when the air tanks are drained, a slow climb to system pressure, or knocking each time it cycles on are the usual signs it is wearing out. Call us to confirm proper fit for your engine. Sold by Pro Gear and Transmission.
