Product Description
276962X TF-500 Air Compressor – Bendix Style Replacement
The 276962X TF-500 air compressor is a heavy-duty replacement unit used in commercial truck air brake systems. This engine-driven compressor is designed to supply compressed air required to operate air brakes, parking brakes, and other pneumatic components on heavy trucks, buses, and vocational equipment.
Compressors in the TF-500 family are widely used on Detroit Diesel powered vehicles and other commercial engines that require dependable air system performance. The unit functions as the primary source of compressed air for the braking system, continuously replenishing air reservoirs so the vehicle maintains proper braking pressure during operation.
This replacement compressor follows the proven Bendix Tu-Flo® 500 design, a two-cylinder reciprocating piston compressor engineered for durability in demanding fleet applications. The TF-500 compressor series typically produces approximately 12 cubic feet of air per minute at 1250 RPM, allowing the air brake system to maintain proper reservoir pressure for safe braking operation.
Most TF-500 compressors used on Detroit Diesel engines feature a flange mount design with water cooling, allowing them to operate reliably in high-temperature engine compartments common in Class 7 and Class 8 trucks.
276962X TF-500 Air Compressor Overview

Purpose of the Air Brake Compressor
The air compressor is the heart of a commercial vehicle’s air brake system. It continuously pumps compressed air into storage reservoirs so the braking system can function correctly. Without a properly operating compressor, the air system cannot maintain pressure needed for service brakes, parking brakes, and emergency braking functions.
If the compressor begins to wear internally, drivers may notice slower air pressure build-up, oil contamination in the air system, or irregular governor cycling. Replacing the compressor restores normal air system performance and helps maintain safe braking operation.
Ace Motor Parts Installation Tip
When installing a replacement air brake compressor, many technicians recommend inspecting or replacing the air governor, discharge line, and air dryer cartridge. Contamination from a failing compressor can travel through the air system and affect other components, so servicing related parts at the same time can help prevent repeat failures.
