OVERVIEW
Genuine VW/Audi N-911-649-01 is an individual mounting bolt for the original oil-pump attachment in the verified applications below. The recessed drive, bearing flange and threaded shank are shown in the archive product photograph.
Technical details and contents
- Factory part number: N-911-649-01 / N91164901.
- Factory nominal fastener specification: M8 × 65.
- Application: assigned oil-pump mounting connection; diagram position varies by vehicle.
- Quantity supplied: one individual bolt.
- Pump, drive components, seals and other mounting hardware are separate.
The nominal designation identifies the functional fastener size. It is not a packaged shipping measurement. Neighboring fasteners in the pump assembly have different lengths and factory numbers, so select the assigned bolt for its exact location.
Function in the lubrication system
This fastener retains the oil pump at its specified mounting point. The pump attachment must remain correctly seated and aligned during operation. Correct mounting hardware supports the intended assembly, but the bolt does not regulate oil pressure or repair internal pump wear.
Common reasons to replace
- The original bolt is missing following oil-pump or engine service.
- The recessed drive has become rounded or damaged.
- Thread damage prevents smooth installation by hand.
- The shank is bent, or the bearing surface is damaged.
- The exact factory repair procedure requires replacement during reassembly.
Inspect the receiving threads, pump mounting surfaces and associated components before installing replacement hardware. A new fastener will not correct a cracked mounting point, damaged pump housing, restricted oil pickup or another lubrication-system fault.

Installation guidance
Follow the factory oil-pump removal and installation procedure for the exact engine. Maintain cleanliness when the lubrication system is open and prevent debris from entering oil passages. Check the condition and placement of the pump, seals and drive components before fastening.
Start the bolt by hand with the pump properly aligned. Use the correct recessed-drive tool and follow the specified tightening sequence, torque, angle and renewal instructions for this mounting point. Do not substitute a torque value from an adjacent oil-pan or pump-cover fastener.
If the repair began because of an oil-pressure concern, complete the required diagnosis and post-repair checks. Replacement mounting hardware alone does not establish that the pump or oil-pressure system is operating correctly.
Ordering information
This listing contains one genuine mounting bolt. Confirm the required quantity and any additional seals or fasteners before beginning the repair. The oil pump, oil, filter, drive chain and a complete installation kit are not included.
