21949471 — Rocker Arm Voe21949471 For Volvo Engine Tad1170-72Ve Tad1180-83Ve Dump Truck A25D A30D

This rocker arm is a critical component within the engine's valve train, responsible for transferring the motion from the camshaft to the valves. Manufactured from hardened steel to withstand high impact and wear, it ensures precise valve timing compared to a worn arm that may have excessive play. Operators might observe increased engine noise, particularly ticking or tapping sounds from the cylinder head, and a gradual reduction in engine performance when this part is failing.

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 failing rocker arm often first manifests as an audible ticking or tapping noise from the engine's cylinder head area. If ignored, this noise can become louder, and the engine may start to run rough or lose power due to improper valve lift. Continued operation risks damage to the camshaft and valve seat.

Installation Tip

Ensure the valve lash is correctly adjusted after installing a new rocker arm to prevent improper valve seating. Do not reuse old adjustment shims, as they may be worn and affect the setting.

Service Note

When replacing a rocker arm, inspect the camshaft lobes and valve stems for signs of wear or pitting.
