289184X TF 400 Air Compressor Bendix Replacement

289184X TF-400 Air Brake Compressor – Bendix Style Replacement

The 289184X TF-400 air compressor is a heavy-duty replacement compressor designed for commercial truck air brake systems. This unit is currently in stock and ready for shipment from Ace Motor Parts. It supplies compressed air required to operate service brakes, parking brakes, and other pneumatic components used on heavy trucks, buses, and vocational vehicles.

Air compressors are an essential part of heavy-duty braking systems. The compressor builds air pressure and stores it in the vehicle’s reservoirs so the brake system can function properly during everyday operation.

The TF-400 compressor family has been widely used in commercial vehicle air brake systems for years. These compressors are built to deliver dependable performance in demanding fleet environments where durability and steady airflow matter.

289184X TF-400 Air Compressor Overview

The 289184X compressor follows the proven Bendix Tu-Flo 400 compressor design. This unit uses a two-cylinder reciprocating piston configuration that compresses air through a single-stage process. The TF-400 compressor series typically produces approximately 7.25 cubic feet of air per minute at 1250 RPM, providing a steady air supply for brake systems and auxiliary pneumatic equipment.

Depending on the engine application, TF-400 compressors may use air-cooled or water-cooled configurations along with different mounting arrangements. These compressors are commonly used on heavy-duty trucks and equipment that rely on engine-driven air brake compressors.

Role of the Air Compressor in the Brake System

The air compressor is the heart of a commercial vehicle’s air brake system. It continuously pumps compressed air into storage reservoirs so the vehicle can maintain proper braking pressure.

If the compressor becomes worn or begins to fail internally, the air system may build pressure slowly or fail to maintain the proper operating range. Replacing a worn compressor restores normal air system performance and helps support safe brake operation.

Ace Motor Parts Installation Tip

When installing a replacement air compressor, technicians often recommend inspecting related components such as the air governor, discharge line, and air dryer cartridge. Servicing these parts at the same time can help prevent contamination in the air system and improve long-term reliability.
