21750781 — Belt Tensioner 21750781 22307251 For Volvo Penta Engine Tad570-72Ve Tad552Ve Tad840-43Ve Tad840Ge D8A5-Amg

This is an automatic belt tensioner designed to maintain the correct tension on the serpentine belt driving various engine accessories like the alternator and water pump. Constructed with a durable spring mechanism and robust bearing, it ensures consistent belt pressure for reliable accessory operation, unlike a worn tensioner that allows the belt to slip or become loose. Operators might observe a squealing noise from the belt area, premature belt wear, or notice that accessories are not functioning correctly if the tensioner fails.

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 belt tensioner may first manifest as a persistent squealing or chirping noise from the engine's accessory drive. If the tensioner weakens, the belt may appear to be flapping or slipping, leading to intermittent operation of accessories like the alternator or water pump. Continued operation with a faulty tensioner can cause premature belt failure and damage to accessory pulleys.

Installation Tip

When installing, use a suitable tool to retract the tensioner arm and carefully align it with the belt. Ensure the tensioner is fully seated and the locking mechanism engages correctly.

Service Note

Always inspect the condition of the serpentine belt and all accessory pulleys for wear or damage when replacing the belt tensioner.
