N-909-294-01 Genuine VW/Audi Flywheel Bolt - M10 x 1 x 27 mm

Genuine VW/Audi flywheel bolt, part number N-909-294-01. This original fastener secures the original flywheel or drive plate at its specified crankshaft attachment in the confirmed VW and Audi applications below. One bolt is supplied; the confirmed VR6 flywheel arrangement uses ten bolts.

Technical details

• Original number: N-909-294-01 / N90929401.
• Published nominal thread diameter: M10.
• Published thread pitch: 1.0 mm.
• Published nominal bolt length: 27 mm.
• Internal multipoint drive and cylindrical head, as pictured.
• Published replacement instruction: renew these bolts whenever removed.
• Flywheel, clutch components and additional bolts are separate.

The flywheel-to-crankshaft connection is distinct from the clutch pressure plate attachment. Confirm the original number at the crankshaft fastening position rather than substituting this bolt for a pressure plate screw or a transmission case bolt.

The nominal diameter, fine thread pitch and length distinguish this fastener from other drivetrain hardware. An M10 bolt with a different pitch or length is not an equivalent replacement. This listing is for a single original bolt rather than a ten-bolt package.

Common reasons to replace

Renew the bolt when the flywheel is removed during clutch, flywheel or associated drivetrain service. The published supplier instruction requires replacement each time these bolts are removed, so reinstalling the old set is not the specified service approach for the confirmed application.

Replace a bolt with damaged threads, a rounded multipoint drive, corrosion affecting its seating surfaces or damage from an earlier repair. Inspect the complete fastening arrangement if incorrect hardware or a missing bolt is found.

A loose joint requires diagnosis before reassembly. New bolts do not repair damaged crankshaft threads, a cracked or incorrectly seated flywheel, damaged mating surfaces or an incorrect replacement flywheel. Correct the cause and verify all required components.

Clutch slip, vibration, noise or difficult shifting can have causes beyond this fastener. Follow the appropriate diagnosis instead of treating a replacement bolt as a cure for a worn clutch or faulty flywheel.

Installation and service notes

Follow the factory procedure for the exact engine and installed factory transmission. Support and remove drivetrain components with suitable equipment. Identify the flywheel-to-crankshaft hardware and keep it separate from pressure plate screws and transmission case bolts.

Inspect the flywheel mounting face, crankshaft threaded points and replacement flywheel specification before assembly. Clean and prepare the joint using the prescribed method. Address damaged threads or surfaces before installing the new hardware.

Seat the correct flywheel in the required orientation and start the new bolts by hand. Do not force a mismatched thread or use the bolts to draw an incorrectly seated flywheel into position. Order the required quantity for the confirmed arrangement; one bolt is supplied here.

Use the correct fitting multipoint bit, seated fully in the head. Keep the tool aligned to avoid damaging the drive. Use the approved flywheel holding method rather than improvising a restraint that could damage surrounding components.

Follow the engine-specific tightening sequence and exact torque or angle procedure. No universal torque value is provided. Use only the thread preparation specified by the service procedure; do not add lubricant or additional thread locking compound unless instructed.

For aftermarket flywheels or conversion kits, verify their documented hardware requirements separately. Factory bolt fitment does not establish compatibility with every replacement flywheel. Do not substitute the quantity or fastener specification from an unrelated diesel or automatic-transmission arrangement.

Complete the prescribed inspection and reassembly steps before reinstalling the remaining clutch and transmission components. Perform the required final checks for the repair. Flywheel bolts must be treated as attachment hardware, not as replacement clutch or flywheel components.

Fitment

Confirm N90929401, the original flywheel or drive plate, engine and factory transmission by VIN. One bolt supplied.
