This push arm bearing is a vital component within the engine's valvetrain system, supporting the push arm's rotational movement and ensuring precise valve actuation. It is constructed from hardened steel alloys to withstand high loads and friction, offering superior wear resistance compared to a damaged or worn bearing. Symptoms of failure include unusual clicking or tapping noises from the engine, reduced engine power, and potentially poor combustion if valve timing is affected.
Always verify with serial number before ordering.

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.
An initial sign of a failing push arm bearing is an audible ticking or knocking sound originating from the engine's upper end. If ignored, this noise will likely intensify, and the engine may begin to run rough or lose power due to improper valve timing. Continued operation risks severe damage to the camshaft and cylinder head.
Ensure the bearing seat in the engine block or head is perfectly clean and free from burrs or damage before seating the new bearing. Press the bearing in squarely to prevent any binding or damage to the bearing itself.
Inspect the push arms and camshaft lobes for wear or pitting when replacing the push arm bearing.
