This is a rocker arm assembly, a critical component in the engine's valvetrain that transfers the motion from the camshaft to the valves. It is precision-machined for durability and accurate valve timing, unlike worn assemblies with excessive play. Operators may notice increased engine noise, reduced engine performance, or valve train-related fault codes when the assembly is failing.
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.
The first symptom of a failing rocker arm assembly is often an audible ticking or clattering noise from the engine, especially at idle. If ignored, this can lead to improper valve timing, reduced engine power, and increased oil consumption. The worst consequence is potential damage to the camshaft or valves.
Ensure the camshaft is at the correct position (e.g., TDC on compression stroke for the relevant cylinder) before installing the rocker arms to avoid valve-to-piston contact. Do not overtighten the rocker arm pedestal bolts, as this can damage the cylinder head.
When replacing the rocker arm assembly, inspect the camshaft for wear on the lobes and check the valve seals for leaks.
