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?
Cross-check reference 026109243F together with the Porsche model, production year and engine code.

Engine Rebuild Belts, Tensioners & Rollers – Precision Timing for Reliable Porsche Performance
Engine rebuild belts, tensioners, and rollers are essential components in maintaining your Porsche’s precise engine timing and smooth operation. These parts work together to synchronise the camshaft and crankshaft, ensuring valves open and close at exactly the right time for optimal combustion. Over time, these components can wear or deteriorate, especially under high performance or extended use, making replacement vital during an engine rebuild or major service.
At Design911, we supply a full range of genuine and high-quality belts, tensioners, and rollers for various Porsche models including, 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is designed for strength, accuracy, and long-lasting reliability — ensuring your rebuilt Porsche engine performs flawlessly mile after mile.
What Do Engine Belts, Tensioners & Rollers Do?
These components form the heart of the engine’s timing and
auxiliary systems. They:
- Drive
key engine components, including the camshaft, alternator, and water
pump.
- Maintain
accurate timing for optimal combustion and efficiency.
- Reduce
friction and noise through smooth roller and tensioner operation.
- Ensure consistent belt tension to prevent slippage or premature wear.
Together, they guarantee your Porsche’s engine runs smoothly, efficiently, and reliably — whether cruising or driving at peak performance.
Why Do Belts, Tensioners & Rollers Fail?
Exposure to high temperatures, vibration, and constant
motion causes natural wear over time. Common causes of failure include:
- Aging
rubber belts becoming brittle or cracked.
- Worn
bearings in rollers or tensioners leading to noise or vibration.
- Loss
of tension causing belt slippage or timing misalignment.
- Contamination
from oil or coolant degrading materials.
- Extended maintenance intervals leading to unexpected failure.
Symptoms of failing components include squealing noises, poor engine performance, rough idle, or even timing belt failure, which can cause severe engine damage if ignored.
Why Replace Belts, Tensioners & Rollers During an Engine Rebuild?
Replacing these components during an engine rebuild ensures long-term reliability and eliminates the risk of future timing-related failures. A fresh set of belts, rollers, and tensioners restores precision, efficiency, and performance — protecting your investment.
Benefits of replacement include:
- Restored precise timing and smooth operation.
- Reduced risk of catastrophic engine failure.
- Enhanced reliability and longevity of the rebuild.
- Quieter, more efficient engine performance.
All components available from Design911 are made using premium-grade materials, precision bearings, and advanced heat-resistant compounds, ensuring maximum durability and performance in high-stress Porsche engines.
