239-7708 Bushing — Cat 307C 307D

This bushing is a critical component within the engine's valvetrain system, designed to provide a low-friction pivot point for valve components. It is manufactured to meet stringent OEM material and dimensional standards, ensuring superior wear resistance compared to a worn or damaged bushing. Operators may notice a loss of engine power, increased oil consumption, or unusual ticking noises from the engine if this bushing begins to fail.

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

A worn bushing may initially cause a slight increase in valve lash or a subtle ticking sound from the engine. If left unaddressed, this can lead to increased oil consumption as oil bypasses the worn area, and eventually, reduced engine performance and potential valve seating issues.

Installation Tip

Ensure the cylinder head is thoroughly cleaned before installing the new bushing to prevent debris from compromising the fit. Avoid using excessive force or improper tools, which can distort the bushing or damage the valve guide.

Service Note

Inspect valve guides and valve stems for wear or damage when replacing valve bushings.
