What This Product Does

The roller guides the belt along its intended path within the engine belt-drive assembly. It is a deflection roller rather than the separate belt tensioner.

Functions

• Guides the belt through the drive assembly.
• Provides a rotating contact surface along the belt path.
  
  

Technical Details

• Part reference: 94810212002.
• Brand: OE Match.
• Assembly description: deflection roller with fastening screw and cap.
  
  

Symptoms of Fault

Rumbling, whining or chirping around the belt drive can warrant inspection of the rollers and tensioner. Visible pulley wobble, belt dust or abnormal belt wear also call for diagnosis; these signs do not identify this roller as the cause on their own.

Why Replacement Matters

A worn roller bearing can become noisy or seize, disrupting belt operation. Inspect the belt, tensioner and neighbouring pulleys when investigating a fault rather than replacing one component without checking the assembly.

OE Reference

94810212002 replaces the earlier Porsche references 94810212000 and 94810212001.

FAQs

Does an undamaged belt rule out roller wear?
No. Roller bearings can deteriorate even when the belt has no obvious surface damage.

Should the other belt-drive components be checked?
Yes. Assess the belt, tensioner and remaining rollers for wear when carrying out the repair.

Check fitment for your specific vehicle (model, year, engine) before ordering.

Diagram Ref No 19

What This Product Does
The roller provides the rotating contact surface used by the auxiliary belt tensioning mechanism. It works with the associated tensioner hardware to support belt travel; it is not an engine timing component or a complete tensioner assembly.

Functions

• Provides rolling contact with the auxiliary drive belt.
• Supports belt guidance through the tensioning mechanism.
• Allows renewal of the roller component when wear is identified.

Technical Details

• Brand: OE Match.
• Product reference: 9A110221200.
• Component type: drive belt tensioning roller.
• The 955 Cayenne diagram describes this reference as a tensioning roller with cap.
• Several diagrams identify the roller as component 2 of a four-component assembly; this is an assembly position, not a pack quantity.
• Associated levers, hydraulic tensioners, protective caps and screws are identified separately in the diagrams; do not assume a complete mechanism is included.

Symptoms of Fault

• Chirping or squealing from the auxiliary belt area.
• A rumbling or whining roller bearing.
• Visible pulley wobble or abnormal belt tracking.
• Belt dust, glazing or uneven belt wear.

These signs can also arise from the belt, other pulleys or the tensioner mechanism. Establish the source before selecting replacement parts.

Why Replacement Matters
A worn or seized roller can interrupt belt operation and contribute to further belt wear. Replacing a confirmed faulty roller addresses that component without confusing it with the separately identified tensioner hardware. Inspect the belt and neighbouring pulleys during the repair, and check for contamination or wear elsewhere in the mechanism. OE Match's Porsche-focused replacement programme uses application and original-reference checks to identify suitable components.

FAQs

Does an undamaged belt rule out roller wear?
No. The roller bearing may deteriorate even when the belt has no obvious external damage.

Should the other belt-drive components be checked?
Yes. Inspect the belt, adjacent rollers and tensioner mechanism so that another worn component is not overlooked.

How should compatibility be confirmed?
Compare reference 9A110221200 with the required component and check the precise vehicle application, including engine and production details.

Drive Belt.
The OE Match Drive Belt is a high-quality replacement auxiliary drive belt designed to transmit power from the engine crankshaft to essential engine-driven accessories. Manufactured to OE specifications for fit, durability and performance, this multi-ribbed belt ensures the efficient operation of components such as the alternator, water pump, air conditioning compressor and power steering pump, depending on the vehicle's specification.  

Fits:

• Porsche 955 Cayenne S 4.5L V8 2003-06
• Porsche 955 Cayenne Turbo 4.5L 2003-06
• Porsche 955 Cayenne Turbo S 4.5L 2006>> 

Manufactured from premium-grade EPDM rubber with high-strength tensile reinforcement, the drive belt is engineered to withstand constant flexing, high rotational speeds, heat and demanding operating conditions. Precision-moulded ribs provide excellent grip and smooth power transmission while minimising slippage and noise.

What This Product Does:

• Transfers power from the engine crankshaft to auxiliary components.
• Drives systems such as the alternator, water pump, air conditioning compressor and power steering pump where applicable.
• Maintains reliable operation of essential engine accessories.
• Supports battery charging and electrical system performance.
• Helps maintain coolant circulation where the water pump is belt driven.
• Enables correct operation of the air conditioning system.
• Provides smooth and efficient power transmission.
• Contributes to overall engine reliability and performance.

Symptoms Of Wear Or Failure:

• Squealing or chirping noises from the engine bay.
• Visible cracks, fraying or glazing on the belt surface.
• Belt slippage during operation.
• Battery or charging system warning light.
• Reduced alternator output.
• Air conditioning performance loss.
• Engine overheating if the water pump is belt driven.
• Heavy steering if the power steering pump is belt driven.
• Excessive belt vibration.
• Complete loss of accessory drive if the belt breaks.

Why Replacement Matters:

• The auxiliary drive belt operates continuously whenever the engine is running and is exposed to constant tension, heat, vibration, moisture and contamination from dirt and oil. Over time, the belt material can harden, crack, stretch or wear, reducing its ability to transfer power efficiently.
• A worn or damaged drive belt can cause poor performance of engine accessories, leading to charging issues, reduced cooling efficiency, loss of air conditioning or power steering assistance, and in some applications, engine overheating. If the belt fails completely, multiple engine systems can stop functioning simultaneously, potentially resulting in vehicle breakdown.
• Replacing a worn drive belt restores reliable power transmission and helps prevent unexpected accessory failures. An OE Match replacement provides factory-style fitment, precise rib geometry and long-lasting durability, ensuring dependable performance and helping maintain the reliability expected from your Porsche.

Engine Drive Belt Vibration Damper

The engine drive belt vibration dampe is a vital component in the auxiliary belt system of the Porsche 955 Cayenne S and Cayenne Turbo. Its primary role is to absorb torsional vibrations generated by the engine and rotating accessories, ensuring smooth belt operation and protecting critical components such as the alternator, power steering pump and air conditioning compressor.

Fits:

• Porsche 955 Cayenne S 4.5L V8 2003-06
• Porsche 955 Cayenne Turbo 4.5L 2003-06
• Porsche 955 Cayenne Turbo S 4.5L 2006>>  

Diagram ref no 3

Designed for high-performance V8 engines, this damper helps maintain refinement, reliability and longevity in demanding driving conditions.

What Does an Engine Drive Belt Vibration Damper Do?

As the engine runs, rotational forces and sudden load changes create vibrations within the belt drive system. The vibration damper:

• Reduces belt oscillation and resonance
• Protects auxiliary components from shock loads
• Maintains stable belt tracking and tension
• Helps prevent premature belt and pulley wear

On powerful models like the Cayenne S and Cayenne Turbo, effective vibration control is essential to ensure smooth power delivery and long-term mechanical reliability.

Why Do Vibration Dampers Fail on Porsche Cayenne Models?

Over time, vibration dampers are exposed to heat cycles, engine torque and material fatigue. Common causes of failure include:

• Degradation of the internal rubber bonding
• Cracks or separation within the damper assembly
• Age-related hardening or loss of damping ability
• Oil contamination accelerating material breakdown

Typical signs of a failing damper include:

• Belt noise or chirping
• Visible cracking or wobble
• Increased vibration from the engine bay
• Premature auxiliary belt wear

Why Replace the Drive Belt Vibration Damper?

Replacing a worn vibration damper helps restore:

• Smooth and stable belt operation
• Reduced stress on auxiliary components
• Correct belt alignment and longevity
• Overall engine refinement and reliability

Continuing to drive with a failing damper can lead to belt failure or damage to expensive accessories, resulting in increased repair costs.
