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 piston selector may include a slight decrease in engine oil pressure or a subtle increase in exhaust smoke. If left unaddressed, the issue can lead to uneven piston cooling and potential lubrication starvation. This can result in accelerated engine wear and reduced overall performance.

Installation Tip

Ensure the oil passages are completely clean and free of debris before installation, as even small contaminants can impede the selector's function. Avoid overtightening the retaining bolts, which can distort the component or damage the engine block.

Service Note

Inspect the piston cooling jets for blockage or wear when replacing the piston selector.
