The OE Match Cam Idler Roller is a high-quality replacement timing belt guide roller designed to support and guide the camshaft timing belt within the engine timing system. Featuring an outer diameter of 32mm and a width of 21mm, this precision-engineered idler roller helps maintain correct belt routing, alignment and stability throughout engine operation.
Fits:
- Porsche 924S 2.5L 1986-87
- Porsche 944 2.5L 8V 1982-87
- Porsche 944 Turbo 2.5L 8V 1985-88

Manufactured to OE specifications for fit, function and durability, the roller is designed to withstand constant rotational loads, engine heat and high-speed operation. It is an essential service component during timing belt replacement and engine maintenance, helping to ensure reliable timing system performance and long-term engine protection.
What This Product Does:
- Guides and supports the camshaft timing belt.
- Maintains correct timing belt alignment and routing.
- Reduces belt vibration and unwanted movement.
- Promotes even belt wear across the timing system.
- Helps ensure accurate synchronisation between the crankshaft and camshaft.
- Supports smooth and reliable engine operation.
Symptoms Of Wear Or Failure:
- Squealing, chirping or grinding noises from the timing belt area.
- Excessive timing belt vibration.Rough or noisy bearing operation.
- Visible wear on the roller surface.Timing belt misalignment.
- Uneven or accelerated timing belt wear.
- Bearing play or looseness within the roller.
- Timing belt failure risk in severe cases.
Why Replacement Matters:
- The cam idler roller operates continuously whenever the engine is running and is subjected to constant rotational speeds, heat and bearing loads. Over time, the internal bearing can wear, lubrication can deteriorate and the roller surface may become damaged.
- A failing idler roller can cause timing belt misalignment, increased belt wear and excessive stress on other timing system components. In severe cases, bearing seizure or roller failure can lead to timing belt damage, potentially resulting in significant engine damage and expensive repairs.
