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.

• Slip or squeal
• Wear prematurely
• Mis-track off pulley grooves
• Lead to loss of accessory function (e.g., alternator charging, power steering assist, air conditioning)

Replacing a failing pulley restores smooth belt travel, helps reduce noise under the hood, and improves the belt’s service life.

Replace this idler pulley if you notice:
•  Squealing or chirping from the front accessory belt area
•  Belt wear or fraying
•  Vibration or noise from the pulley bearing
•  During belt system maintenance or tensioner replacement

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.
