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

Initial signs of a failing air dryer refrigerant include a noticeable decrease in engine power and increased exhaust smoke. If left unaddressed, the moisture and contaminants will begin to degrade engine seals and internal components. This can lead to costly repairs and prolonged equipment downtime.

Installation Tip

Ensure the air intake system is clean before installation to prevent debris from entering the engine. Do not overtighten the housing, as this can damage the seals.

Service Note

Inspect the air filter and intake hoses for wear or damage when replacing the air dryer refrigerant.
