Product Description
3558022X Air Compressor – Cummins Replacement
The 3558022X air compressor is a heavy-duty replacement designed for select Cummins diesel engine applications used in commercial truck air brake systems. This compressor is currently in stock and ready for shipment from Ace Motor Parts. Engine-driven air compressors provide the compressed air required to operate service brakes, parking brakes, and other pneumatic systems found on medium-duty and heavy-duty trucks.
This compressor is commonly used with Cummins C-Series diesel engines, including applications such as the 6C8.3 and C8.3 engines equipped with iron cylinder heads and through-drive power steering pump configurations. The design uses an 11-tooth spline shaft to drive the compressor while maintaining compatibility with common Cummins accessory drive systems.
Air compressors are essential to the operation of commercial vehicle brake systems. The compressor continuously builds and maintains pressure in the vehicle’s air reservoirs, allowing the braking system to function correctly and ensuring reliable stopping performance under normal operating conditions.
3558022X Air Compressor Overview
The 3558022X compressor is designed for demanding commercial truck service where durability and consistent airflow are required. The unit uses a single-cylinder compressor configuration with engine-supplied lubrication and water cooling to help manage operating temperatures during extended use.
This configuration allows the compressor to operate at engine speeds up to approximately 3000 RPM while maintaining reliable air delivery for braking systems and other pneumatic components used on heavy-duty vehicles.
