Genuine Ferrari Gearbox Housing Mounting Screw Bolt 109997

Genuine Ferrari Gearbox Housing Mounting Screw Bolt 109997 - OEM Drivetrain Hardware

The 109997 screw bolt is a genuine Ferrari fastener engineered to mount and secure the gearbox housing, holding the transmission casing in exact alignment under load. Housing bolts do critical structural work: they keep mating faces sealed against oil, maintain bearing alignment, and resist the constant vibration and torque reaction of the drivetrain. A stretched, corroded, or incorrect bolt here risks oil seepage, fretting between housing faces, and in the worst case, a loosened casing. Ordering the genuine 109997 from European Auto Spares keeps your Ferrari's gearbox mounted exactly as the factory intended.

What This Mounting Bolt Does

The 109997 bolt clamps the gearbox housing sections and mounting points together at Ferrari's specified preload. Correct preload keeps the housing faces in full contact so seals do their job and internal components stay in alignment. Because the gearbox reacts against engine torque on every drive, these bolts live in a high-vibration environment — which is exactly why Ferrari specifies dedicated OE hardware rather than generic fasteners for the job.

Signs the Bolt Needs Replacing

Replace housing bolts when threads are stretched, galled, or corroded, when the head or shank shows damage, or whenever the gearbox has been opened for service — critical fasteners like these are routinely renewed rather than reused. Warning signs include oil weeping from housing joints, witness marks of movement between casing faces, and bolts that will not hold their specified torque. Any of these means the clamping integrity of the housing is compromised.

Why the Genuine Bolt Matters

A gearbox housing bolt must deliver precise, even clamping across the whole joint: wrong thread fit, incorrect length, or softer material changes the preload and can distort the housing or leave the seal under-compressed. The genuine Ferrari 109997 is manufactured to the original dimensional and material specification, so each bolt in the set pulls its designed share of the load. With drivetrain hardware, the cost of a failed joint dwarfs the price of the correct bolt many times over.

Fitting Notes

Gearbox housing bolts must be fitted by a qualified technician following the correct tightening sequence and torque specification for that housing — uneven tightening distorts the casing and invites leaks. Always fit new bolts where the workshop procedure calls for renewal, clean all threads and mating faces before assembly, and confirm the seal and gasket are serviceable while the housing is accessible. Never reuse a bolt with stretched or damaged threads.
