Product Description
286544X TF-501 Air Compressor – Bendix Replacement for Mack Truck Air Brake Systems
The 286544X TF-501 air compressor is a remanufactured replacement designed for Mack commercial truck air brake systems. This compressor is available from Ace Motor Parts and is built for reliable performance in demanding heavy-duty fleet applications. Engine-driven air compressors are responsible for generating compressed air used by service brakes, parking brakes, and auxiliary pneumatic systems found on commercial vehicles.
The Bendix TF-501 compressor is commonly installed on Mack truck engines that utilize a flange-mounted compressor without a gear assembly. Its durable two-cylinder piston design provides consistent airflow while maintaining stable operating temperatures through a combined air and water cooling system.
Mack Truck Applications
The 286544X compressor is typically used on Mack heavy-duty trucks and vocational vehicles that require a TF-501 style compressor. These compressors supply compressed air for the braking system while also supporting pneumatic accessories such as suspension systems and other air-operated components.
The compressor features a flange mount engine-driven configuration and is commonly installed on Mack diesel engines used in highway tractors, vocational trucks, and other commercial vehicle platforms.
TF-501 Compressor Design
The TF-501 compressor utilizes a two-cylinder reciprocating piston design that compresses air through a single-stage compression process. With an airflow rating of approximately 12 cubic feet per minute at 1250 RPM, the compressor provides dependable air delivery for heavy-duty air brake systems.
The unit uses a water and air cooling system that helps maintain proper operating temperatures during extended operation. The compressor is lubricated through the engine’s oil system and features threaded discharge ports for reliable connection to the air system.

Part Number Reference
The 286544X air compressor replaces several TF-501 compressor numbers used in Mack heavy-duty truck applications. Common interchange numbers include Bendix part numbers such as 286544, 286544R, 286583, and 288982, as well as Mack compressor numbers including 303GB-578 and 303GB-587. These compressors are designed for use in commercial vehicles that utilize TF-501 style engine-driven air compressors.
What Trucks Use the 286544X Air Compressor?
The 286544X TF-501 compressor is commonly installed on Mack commercial trucks and vocational diesel vehicles that utilize flange-mounted air compressors. These compressors are typically found on highway tractors, construction trucks, and fleet vehicles that rely on air brake systems for reliable stopping performance.
In some installations, the EL13111 compressor may also be used as an alternate replacement depending on the engine configuration and mounting arrangement.
The Role of the Air Compressor in Commercial Brake Systems
The air compressor is one of the most critical components of a heavy-duty truck braking system. It continuously pumps compressed air into the vehicle’s air tanks so the braking system maintains the pressure required for safe and reliable stopping performance.
If the compressor begins to wear internally, the air system may take longer to build pressure or may struggle to maintain proper operating pressure. Replacing a worn compressor restores air system performance and helps ensure the vehicle’s braking system operates correctly.
