The 1117994 Caterpillar air compressor is sold as an aftermarket unit for Caterpillar and Mack engine applications. It mounts on the engine and is driven by gear or belt. The compressor draws in filtered air and compresses it, then stores it in the reservoir tanks that supply braking and other pneumatic functions on the truck. A governor tells it when to stop and start building pressure, so the reservoirs stay within their working range. Sold as a single unit (1 each) by Pro Gear and Transmission. Call us to confirm proper fit for your engine.
