Gates T43139 Engine Timing Belt Tensioner

Gates Timing Belt Tensioner for Volvo Engines

The Gates T43139 timing belt tensioner is built for Volvo engine timing service where stable belt control matters. It is engineered with OE-quality fit and performance to help maintain proper belt tension and reduce the need for manual tensioning during installation.

Built from steel with a spring-style tensioner design, this Gates PowerGrip timing belt tensioner uses a smooth backside contact surface and a single pulley layout for consistent operation in timing belt systems. It is a direct-fit engine timing belt tensioner for select Volvo S40, S60, V40, V70, XC70, XC90, C70, S70, and S80 applications.

Key Features

• Steel construction for durable timing system service
• Spring tensioner design for controlled belt loading
• Smooth/backside contact surface
• Single pulley configuration
• OE-quality fit and performance for Volvo timing belt service
• Gates PowerGrip timing belt tensioner line

Product Details

Gates PowerGrip timing tensioners are designed and tested to support belt life and maintain optimal belt tension in engine timing systems. The T43139 is a timing belt tensioner assembly with an 8 mm inside diameter, 27.1 mm width, and 59 mm outside diameter. It is intended for interference-engine Volvo applications where accurate belt tension is critical to valve train operation. This part cross-references URO 30638277 for the same application.

What This Part Helps Address

• Timing belt slack or inconsistent belt tension
• Belt noise caused by worn tensioner components
• Premature timing belt wear from poor belt control
• Timing service issues on interference-engine Volvo applications
• Loss of proper belt tracking in the engine valve train system
