OVERVIEW
Genuine VW/Audi flywheel bolt, part number N-907-059-01. This original M10 x 1 x 43 fastener attaches the factory flywheel at its specified crankshaft connection on the configurations below. The listing supplies one bolt, allowing you to select the quantity required by the exact repair procedure.
Technical details
- Original number: N-907-059-01 / N90705901.
- Published nominal size: M10 x 1 x 43.
- Combined external hex and internal multipoint head with a flange; the archive image shows a colored thread patch.
- Assigned application: factory flywheel-to-crankshaft mounting hardware.
- One bolt supplied. Flywheel, clutch, pressure plate and other fasteners are separate.
The flywheel forms part of the rotating assembly at the engine-to-transmission connection. Its mounting hardware holds the flywheel at the crankshaft attachment. Correct bolt selection, engagement and tightening are necessary for the complete assembly.
This bolt is assigned to the factory manual-transmission flywheel in these profiles. It does not replace automatic-transmission drive-plate hardware or the separate pressure-plate bolts. Check the actual factory flywheel and original fastener number before ordering.
Common reasons to replace
This original flywheel bolt is cataloged as one-time-use hardware. Renew it after removal during flywheel or clutch service; obtain the full quantity required for the exact assembly. Inspect for missing bolts, damaged threads, deformed heads, worn drive recesses or corrosion that compromises installation.
Previous repairs can leave unsuitable substitutes or damage the internal drive. Verify the complete fastener set before reassembly. Do not mix hardware lengths or assume that bolts supplied with an aftermarket flywheel use the original tightening procedure.
Flywheel noise, vibration, clutch engagement problems or other drivetrain symptoms require diagnosis of the flywheel, clutch and related components. A new mounting bolt cannot restore a worn dual-mass mechanism, damaged friction surface, cracked flywheel or stripped crankshaft threads.
Installation and service notes
Follow the factory procedure for the exact engine, transmission and flywheel arrangement. Use the prescribed support and locking equipment when removing or installing the transmission and flywheel. Inspect the attachment surfaces, locating arrangement and mating threads before assembly.
Position the correct flywheel as specified and start the required fasteners by hand without cross-threading. Do not use the bolts to force a misaligned flywheel into place. Confirm the hardware matches the original mounting positions and any replacement-flywheel instructions.
Use the correctly fitting multipoint tool and follow the specified tightening sequence, torque and any additional angle. Observe the required thread preparation and fastener replacement instructions. The visible thread patch does not establish its chemical composition or permit adding an unapproved thread compound.
Do not copy a tightening value from a pressure-plate bolt, a different flywheel bolt or an aftermarket flywheel kit. The same nominal thread diameter does not establish the correct procedure.
Complete the required transmission and clutch reassembly checks. Inspect nearby seals and service components while accessible, replacing them only as indicated by diagnosis and the repair instructions. Confirm the operating checks required after the work are complete.
This listing supplies a single original bolt, not a complete flywheel bolt set. Determine the required quantity from the actual assembly and factory procedure.
