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.
Audible air leaks from the compressor housing or a persistent hissing sound are common indicators of a failing compressor seal. If left unrepaired, the compressor may struggle to maintain adequate air pressure, leading to unreliable braking performance and potential system failures. Inadequate air pressure poses a significant safety risk due to compromised braking capability.
Thoroughly clean the compressor housing and all internal parts before installing new seals and gaskets. Ensure all moving parts are lightly lubricated with appropriate compressor oil to prevent damage during initial startup.
Inspect the air dryer and air lines for moisture or debris when rebuilding the air compressor with this kit.
