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.
