20405705 — Pulley Voe20405705 For Volvo Penta Engine Tad520Ge Td520Ve Wheel Loader L40B L45B

This pulley is a critical component of the engine's accessory drive system, responsible for maintaining proper tension on the V-belt. It ensures consistent power transfer to components like the alternator and water pump, preventing slippage and premature belt wear. A worn pulley may exhibit a wobbly rotation or produce a high-pitched squealing noise under load, indicating potential bearing failure or a damaged pulley surface.

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 pulley may first manifest as an intermittent squealing noise from the engine bay, especially during startup or acceleration. If ignored, the noise can become constant, and the pulley may begin to wobble, leading to uneven belt wear and reduced efficiency of driven accessories. Ultimately, a seized pulley can cause the accessory belt to break, disabling critical functions like cooling and charging.

Installation Tip

Ensure the new pulley's mounting surface is clean and free of debris before installation to guarantee a flush fit. Avoid overtightening the mounting bolt, as this can strip threads or damage the pulley's bearing.

Service Note

Always inspect the condition of the accessory drive belt and the tensioner assembly when replacing the pulley.
