Product Description
101242X TF-400 Air Compressor – Bendix Replacement Base Mount Compressor (In Stock)
The 101242X TF-400 air compressor is a heavy-duty replacement compressor designed for commercial vehicle air brake systems. This compressor is in stock and ready to ship from Ace Motor Parts. Engine-driven compressors supply the compressed air required for service brakes, parking brakes, and other pneumatic systems used on trucks and vocational equipment.
The TF-400 compressor family is known for its compact design and dependable performance in medium- and heavy-duty applications. Its durable two-cylinder piston construction provides consistent airflow while maintaining reliability in demanding fleet environments.
Vehicle and Equipment Applications
The 101242X compressor is typically installed on commercial trucks, buses, and vocational vehicles equipped with engine-driven air brake systems. The base-mount configuration allows the compressor to be installed on a variety of engine accessory drive systems where a pulley-driven compressor is required.
This compressor configuration features left-side air inlet and outlet ports and a base oil inlet arrangement depending on installation orientation.
TF-400 Compressor Design
The Bendix TF-400 compressor uses a two-cylinder reciprocating piston design that compresses air through a single-stage process. The compressor produces approximately 7.25 cubic feet of air per minute at 1250 RPM, providing sufficient airflow for commercial vehicle brake systems. :contentReference[oaicite:3]{index=3}
The compressor is typically driven through a belt-driven pulley system and utilizes a water-cooled cylinder head to maintain proper operating temperature during extended operation. Engine lubrication ensures long service life under demanding operating conditions.

What Vehicles Use the 101242X Air Compressor?
The 101242X TF-400 compressor is commonly installed on medium- and heavy-duty trucks, buses, and vocational vehicles that require a base-mounted pulley-driven air compressor. These compressors are used in commercial vehicle platforms where a compact air compressor design is required to maintain air brake system pressure.
The Role of the Air Compressor in Truck Brake Systems
The air compressor is one of the most critical components of a commercial vehicle braking system. It continuously compresses air and stores it in reservoirs so the braking system maintains proper operating pressure.
If the compressor becomes worn internally, the air system may take longer to build pressure or struggle to maintain the required pressure levels. Replacing a worn compressor restores proper air system performance and helps ensure reliable braking operation.
