23607402 Tensioner | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta belt tensioner, maintaining correct tension on the drive belt as it stretches and as components move. Consistent tension is what keeps the belt gripping without overloading the bearings it drives.

• Volvo Penta 557

• Volvo Penta 527
• Volvo Penta 627SV

⚙️ Key Features

• OEM Volvo Penta part number 23607402
• System group: Alternator, Charging, Electric Motor, Electric Drives
• Net weight: 0.712 kg

🔌 Function

The tensioner applies a controlled spring load to the drive belt, taking up slack as the belt stretches and damping the tension fluctuations caused by engine pulses. That steady tension is what prevents slip without over-loading driven bearings.

⚠️ Common Signs of Failure

• Belt squeal, slipping or visible flutter in the belt run
• Tensioner arm at the end of its travel or not moving freely
• Bearing noise or roughness felt in the tensioner pulley
• Uneven or accelerated belt wear
• Rattling or knocking from the tensioner assembly

🛠️ Service Notes

• Renew the tensioner and the belt together, and while the belt is off check the other pulleys for wear, roughness in the bearing and any wobble
• Note the belt routing and the tensioner's mounting position and stops before removing the old unit, and check the new one carries the same pulley and offset
• Locate the tensioner properly on its dowel or stop and tighten it to the workshop manual figures — a tensioner not sitting square will run the belt off line and destroy it
• Wind the tensioner back with the correct tool or square drive, fit the belt over the pulleys by hand and release the tensioner onto it; never lever a belt on with a screwdriver and never use the tensioner arm as a pry bar
• Check every rib or tooth is seated in its groove, turn the engine over by hand, then run it up and recheck belt run and tension after the first period of running, following the procedure for your engine
