Air is pumped into storage reservoirs where it becomes available for service brakes, parking brakes, suspension controls, and other pneumatic equipment installed on commercial vehicles. Reliable compressor performance is essential for maintaining consistent braking pressure and proper system operation.\u003c\/p\u003e \u003cp\u003eThe TF-501 compressor platform has been used for decades on a variety of heavy truck engines and specialty equipment due to its rugged construction and dependable airflow output. The pulley drive configuration makes this unit suitable for belt-driven compressor systems commonly used on medium and heavy-duty truck applications.\u003c\/p\u003e \u003ch3\u003eCompressor Construction and Operation\u003c\/h3\u003e \u003cp\u003eThe TF-501 is built around a \u003cstrong\u003etwo-cylinder reciprocating piston design\u003c\/strong\u003e which provides stable air delivery during continuous operation. Each cylinder compresses incoming air during the piston stroke, allowing the compressor to generate a steady supply of compressed air while the engine is running.\u003c\/p\u003e \u003cp\u003eWith an airflow output of approximately \u003cstrong\u003e12 cubic feet per minute at 1250 RPM\u003c\/strong\u003e, the TF-501 is capable of maintaining the air supply required for modern air brake systems even under demanding operating conditions such as frequent braking or high accessory air usage.\u003c\/p\u003e \u003cp\u003eThis compressor utilizes a \u003cstrong\u003ebelt-driven pulley system\u003c\/strong\u003e connected to the engine. Engine oil is supplied to the compressor through a dedicated lubrication line which ensures internal components remain properly lubricated. The compressor housing is designed to dissipate heat through a combination of \u003cstrong\u003eengine coolant circulation and external airflow\u003c\/strong\u003e, helping maintain stable operating temperatures.\u003c\/p\u003e \u003cp\u003eDuring operation, the compressor works with the vehicle’s governor and unloading system to regulate air pressure within the reservoirs. When system pressure reaches the upper limit, the compressor temporarily unloads. Once air pressure drops during brake use, the compressor resumes pumping to restore the air supply.\u003c\/p\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul style=\"font-size: 14px; line-height: 1.7; margin-left: 18px;\"\u003e \u003cli\u003e\u003cstrong\u003eDirect replacement for Bendix TF-501 pulley drive compressors\u003c\/strong\u003e\u003c\/li\u003e \u003cli\u003eDurable \u003cstrong\u003etwo-cylinder reciprocating piston compressor design\u003c\/strong\u003e\n\u003c\/li\u003e \u003cli\u003ePulley drive configuration for belt-driven installations\u003c\/li\u003e \u003cli\u003eApproximately \u003cstrong\u003e12 CFM airflow capacity at 1250 RPM\u003c\/strong\u003e\n\u003c\/li\u003e \u003cli\u003eWater-cooled and air-cooled compressor housing\u003c\/li\u003e \u003cli\u003eRight-side air inlet and outlet configuration\u003c\/li\u003e \u003cli\u003eHeavy-duty construction designed for commercial vehicles\u003c\/li\u003e \u003cli\u003eReplacement unit built to meet or exceed OEM specifications\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eIn stock and ready for shipment from Ace Motor Parts\u003c\/strong\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e \u003ctable style=\"border-collapse: collapse; width: 100%; font-size: 14px;\" border=\"1\" cellpadding=\"10\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e286527X\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eCompressor Model\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eTF-501\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eDrive Type\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003ePulley Drive\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMounting Style\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eBase Mount – 4 Hole\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eCylinders\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e2\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eBore x Stroke\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e2.625 in x 1.50 in\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eDisplacement\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e16.5 cu in per revolution\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eAir Output\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eApprox. 12 CFM @ 1250 RPM\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e3000 RPM\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eHorsepower Requirement\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e4.9 HP @ 3000 RPM \/ 100 PSI\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eCooling System\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eWater and Air Cooled\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMinimum Coolant Flow\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e2.5 GPM\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMinimum Unload Pressure\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e60 PSI\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMaximum Inlet Temperature\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e250°F\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMaximum Discharge Temperature\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e400°F\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eAir Inlet Location\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eRight\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eAir Outlet Location\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eRight\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eDischarge Type\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eFlange\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e41 lbs\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ch3\u003eTypical Vehicle and Equipment Applications\u003c\/h3\u003e \u003cp\u003eThe TF-501 pulley drive compressor is commonly used in heavy-duty truck air brake systems as well as specialty vehicle platforms and industrial equipment.
