OVERVIEW

Genuine guide-rail and pump-retainer hardware

The N-010-272-4 Genuine VW/Audi hex-head bolt is used at two distinct types of engine-mounted connection in the verified applications below: the Volkswagen VR6 timing-chain guide rail and the assigned Audi power-steering pump retainer.

Match the vehicle row and original joint carefully. This bolt is not a universal timing-system fastener or a replacement for every steering-pump bolt. The correct bracket, guide rail and any specified washers remain part of the original assembly.

Technical details

  • Complete factory number: N-010-272-4.
  • Nominal factory specification: M8 × 26.
  • Design: external hex-head threaded bolt.
  • Quantity supplied: one individual bolt.

The nominal specification describes the fastener itself rather than packaged shipping dimensions. Match the complete factory number, original attachment point and head seating arrangement. Similar-looking hardware elsewhere in the same assembly can differ in length, thread size or bearing surface.

Common reasons to replace

  • A bolt is missing after component removal or previous service.
  • The drive head is damaged or rounded.
  • The threads have been crossed, stripped or otherwise damaged.
  • The bolt is bent or its bearing surface no longer seats correctly.
  • A previous repair used incorrect substitute hardware.

Inspect the guide rail or pump bracket, receiving threads and original bearing surfaces before assembly. A replacement bolt cannot repair a cracked guide, damaged pump retainer or stripped receiver. Chain noise, steering effort and fluid leaks require diagnosis of their relevant components.

Vehicle fitment

The table distinguishes the timing guide application from the power-steering retainer application. Match the original component and bolt position, not just the vehicle model.

Installation guidance

Follow the factory timing-system or power-steering pump service procedure for the exact joint. Maintain all required timing and component support precautions when accessing a guide rail. Retain the prescribed washer and bracket arrangement during pump-retainer service.

Align the mating components before engaging the bolt, start the threads carefully and use the correct tool for the actual drive. Follow the factory tightening instruction and sequence for the exact connection. Do not transfer torque values between different applications that happen to use the same bolt number.

After assembly, restore all disturbed components and perform the operating checks prescribed for the serviced system. Investigate remaining looseness or misalignment rather than adding torque.

Ordering information

Supplied as one genuine bolt. Timing guide, chain, pump, retainer bracket, washers and a complete service kit are not included. Confirm the required repair quantity before ordering.
