What This Product Does
The tensioning roller supports the toothed camshaft belt and helps maintain the tension required for consistent camshaft and crankshaft synchronisation. It forms part of the camshaft and valve timing assembly.
Functions
- Guides the camshaft timing belt through its operating path
- Maintains suitable belt tension
- Supports accurate mechanical valve timing
- Allows the belt to travel smoothly around the timing assembly
- Helps limit belt movement, slipping and irregular wear
Technical Details
- Product type: camshaft belt tensioning roller
- Reference number: 026109243F
- Outer diameter: 72 mm
- Width: 24.5 mm
- Diagram ref no 14.
Symptoms of Fault
- Squealing or chirping noises that change with engine speed
- Rumbling or whining from the timing-belt area
- Visible pulley movement or wobble
- Belt dust around the timing cover or pulleys
- Cracking, glazing or uneven wear on the camshaft belt
- A roller that feels rough, tight or loose when inspected
Why Replacement Matters
A worn bearing or damaged tensioning surface can prevent the camshaft belt from running smoothly and holding the correct tension. This may accelerate belt wear or allow timing to become disturbed. The roller should be inspected when renewing the camshaft belt or carrying out engine work, with the surrounding pulley, fastener, washer, bearing sleeve and belt condition checked at the same time.
FAQs
- Should the roller be checked when replacing the belt?
Yes. The roller bearing and running surface are wear points and should be inspected whenever the camshaft belt is renewed. - Can excessive belt tension cause problems?
Yes. Incorrect tension may shorten roller-bearing and belt life, so installation and adjustment should follow the appropriate workshop procedure. - How can suitability be confirmed?

OEMatch Belts / Tensioners / Rollers — Fit, Function, Confidence
These belts, tensioners and rollers control engine timing and auxiliary drives on Porsche models and are commonly replaced during major services and engine rebuilds to restore precise operation and reduce the risk of future failures. Many owners search for genuine or OEM belts; OEMatch offers compatible alternatives engineered to match original-spec dimensions and tolerances for common Porsche applications.
- Timing belts and cambelts
- Auxiliary and serpentine belts
- Tensioner assemblies and hydraulic tensioners
- Idler and guide rollers
- Complete timing kits
Understanding OEMatch Belts / Tensioners / Rollers
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original belts, tensioners and rollers.
OE (Original Equipment) refers to parts matching original specifications for the belts, tensioners and rollers and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM belts, tensioners and rollers engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. OEMatch maintains a wide Porsche-focused catalogue and supports vehicle maintenance with thousands of cross-references and a continuing programme of new part development to help keep Porsche vehicles on the road.
Benefits Include
- Restored timing precision after rebuilds or major services
- Reduced risk of belt slip, noise and bearing failures
- Improved reliability for high-temperature and high-mileage applications
Why Belts / Tensioners / Rollers Wear and Fail
- Ageing rubber and heat exposure causing cracks or loss of flexibility
- Worn bearings in rollers or tensioners generating noise and vibration
- Loss of correct tension leading to slippage or timing misalignment
- Contamination from oil or coolant degrading belt materials
The Importance of Replacing with OEMatch Belts / Tensioners / Rollers
Replacing belts, tensioners and rollers during an engine rebuild or scheduled maintenance restores correct timing relationships, reduces the chance of catastrophic engine damage and supports long-term engine reliability on Porsche models. Using refreshed tensioners and rollers alongside new belts helps ensure even loading, quieter running and consistent operation across the rev range, protecting valves, pistons and ancillary drives.
Advantages
- Parts selected for Porsche applications and original-spec dimensions
- Complete kits available to simplify rebuilds and avoid mixing old and new components
- Options covering timing and auxiliary systems to match common service requirements
