1091317 Air Brake Compressor — Cat 3304 12H

This air brake compressor is essential for generating the compressed air needed to operate the vehicle's braking system. Built to robust standards, it ensures reliable air pressure supply, unlike a worn or failing compressor that may lead to inconsistent braking. Operators may notice a lack of air pressure, spongy brake pedal feel, or continuous compressor cycling when this part is malfunctioning.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing air brake compressor is typically a prolonged time to build air pressure or an inability to reach full system pressure. If ignored, braking performance will degrade, potentially leading to insufficient stopping power. This poses a significant safety risk, especially during operation.

Installation Tip

Ensure the drive pulley and belt are correctly aligned and tensioned before starting the compressor. Do not overtighten the mounting bolts, as this can distort the compressor housing.

Service Note

Replace the air dryer cartridge and inspect the air governor settings when servicing the air brake compressor.
