The idler pulley supports the accessory drive belt, helping to:
• Maintain proper belt routing and tension, preventing slipping and reducing premature wear.
• Guide the belt around engine accessories such as the alternator, power steering pump, A/C compressor, and water pump.
• Ensure smooth operation of components driven by the belt for optimal engine performance.
If the idler pulley wears out or the bearing fails, you may hear squealing, chirping, or grinding noises, see uneven belt wear, or experience belt misalignment - indicators it’s time for replacement.
A worn or failing idler pulley can cause the drive belt to slip, misalign, or break, which can in turn disrupt power to critical engine accessories. Symptoms include belt noise, squealing, or loss of accessory function (e.g., A/C, alternator charging), potentially leading to more costly repairs if ignored. Replacing it with an OE Match pulley ensures proper belt tension and routing, helping keep your engine’s accessory systems functioning smoothly.
Replace the idler pulley if you notice any of the following:
• Squealing, chirping, or grinding noises from the belt area
• Visible belt misalignment or excessive wear
• Pulley bearing play or rough rotation to the touch
• Cracks or deterioration of the pulley surface

replacement for OE 99710224101
Fits on all Porsche 986, 996, 987, 997 models EXCEPT 2.9L (multi hole crank pulley pattern), DFI engines, GT2, GT3 and Turbo.
Increase your engine output by reducing the draw of the engine's ancillaries ie the power steering pump, Air Conditioning, water pump and alternator by slowing them down and reducing the horsepower they use.
Underdrive pulley is one of the cheapest returns for the money spent when it comes to actual performance and horsepower gains for track and street use cars.
Installation tool (wrench) included, new OEM washer and crankshaft pulley bolt is recommended but not included with this product.
Please add Drive Belt for Under Drive Pully cars WITH Aircon Porsche 996/ Boxster 986/997 99610215199/1

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.
