What This Product Does

This bolt provides a fixing within the auxiliary drive belt tensioner lever assembly. The lever, roller, protective cap and hydraulic tensioner are separate components; the bolt does not itself generate belt tension or control valve timing.

Functions

  • Provides the specified threaded fixing for the tensioner lever assembly.
  • Allows damaged or missing fastening hardware to be renewed during belt-system repairs.

Technical Details

  • Brand: OE Match.
  • Part reference: PAF008343.
  • Specified dimensions: M10 x 30.
  • Described in the assembly diagrams as a round-head screw.
  • Reference 99907357901 also appears for this fixing in the 991.1 diagram.
  • Identified as component 3 of 4 within applicable tensioning roller assemblies.

Symptoms of Fault

Inspect for damaged threads, a worn tool-engagement surface, corrosion or missing hardware. Belt squeal, chirping, pulley movement and belt dust warrant inspection of the complete belt drive rather than assuming the bolt is responsible.

Why Replacement Matters

Renewing damaged fastening hardware supports correct reassembly. Check the adjoining lever, roller and mounting threads before fitting, and use the vehicle-specific workshop tightening procedure. Do not substitute tightening figures intended for a different tensioner fastener.

FAQs

Does this include the tensioner or pulley?
No. This product is the lever bolt; the associated assembly components are separate parts.

Is this a timing belt component?
It is identified for the auxiliary V-belt or poly-V-belt tensioner assembly, rather than the engine valve-timing system.

What should I check before fitting?
Confirm PAF008343 against the vehicle application and inspect the mating threads and surrounding belt-drive components.

Diagram ref no 9

The bolt secures the drive belt tensioner to its mounting point, allowing the tensioner to maintain correct auxiliary belt tension and belt alignment. A correctly fitted tensioner bolt is important for reliable belt operation and accessory drive performance.

Functions
•  Replaces the M8x60 drive belt tensioner bolt
•  Secures the drive belt tensioner assembly
•  Supports correct auxiliary belt tensioner mounting
•  Helps maintain belt alignment and stable belt operation
•  Used during drive belt, tensioner, pulley, or accessory drive service
•  Replaces damaged, corroded, stretched, worn, or missing original bolts
•  OE Match replacement fastening for Porsche belt drive repair.

Why Replace This Part?
Drive belt tensioner bolts are exposed to vibration, engine heat, belt load, and repeated service work. A worn, corroded, rounded, stretched, or damaged bolt may not provide correct clamping force and can compromise tensioner mounting. Replacing the bolt during tensioner or belt service helps ensure secure installation and reliable auxiliary drive operation.

When to Replace This Part
•  The drive belt tensioner is being replaced
•  The auxiliary drive belt is being serviced
•  The original bolt is corroded, rounded, stretched, damaged, or missing
•  The tensioner has been removed during engine service
•  Belt noise, poor belt tracking, or tensioner movement is being investigated
•  Preventative replacement is required during major service
•  The vehicle is undergoing Porsche accessory belt drive repair.

Where it fits on the car
This bolt fits at the drive belt tensioner mounting point within the engine accessory belt drive system. Exact position can vary depending on model, engine type, and belt layout.
