VOE21949471 — Rocker Arm Voe21949471 For Volvo Engine Tad1170-72Ve Tad1180-83Ve Dump Truck A25D A30D

This rocker arm is a key component in the valve train of Volvo engines, specifically the D9 and TAD series, transferring the motion from the camshaft to the valves to control the intake and exhaust cycles. Manufactured to precise Volvo specifications, it ensures accurate valve timing and optimal combustion, unlike a worn or bent rocker arm which leads to reduced engine power and increased wear. Operators may notice a ticking or knocking sound from the engine, rough idling, or a loss of engine power.

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

An initial sign of a failing rocker arm can be an audible ticking or tapping noise from the engine, particularly noticeable at idle. If the wear progresses, it can lead to improper valve seating, resulting in a loss of compression and reduced engine power. Continued operation with a damaged rocker arm can cause accelerated wear on the camshaft and valve stem, potentially leading to more extensive engine damage.

Installation Tip

Ensure the camshaft lobe is on the base circle before adjusting the rocker arm clearance to avoid incorrect settings. Do not reuse worn rocker arm pivots or adjusters, as this can lead to premature failure.

Service Note

When replacing a rocker arm, it is advisable to inspect the camshaft and valve springs for wear or damage.
