111-199-101 VW Engine Mount Starter Bolt - Beetle, Bus, Ghia, Type 3

VW Engine Mount & Starter Bolt – 111-199-101

The 111-199-101 is a specialized piece of hardware essential for the structural integrity of your Volkswagen’s drivetrain. This is the "D-shaped" shoulder bolt that passes through the upper right-hand side of the transmission bellhousing. Its unique design serves a dual purpose: it acts as one of the primary mounting bolts securing the engine to the transmission, while simultaneously serving as the mounting stud for the starter motor.

Engineered with a flat side on the bolt head (the "D" shape), this bolt is designed to lock into the recess of the transmission housing. This prevents the bolt from spinning while you tighten the nut from the starter side, making engine installation a one-person job. Using standard hardware in this location is a common mistake that can lead to a loose starter, poor electrical grounding, and excessive vibration that can crack the transmission ears.

Product Highlights & Features Anti-Rotation D-Head: Features the factory-correct flat-sided head to lock into the transmission case, allowing for easy tightening from the engine bay.

High-Tensile Strength: Forged from high-grade steel to handle the torque and shear forces of the engine and transmission mating surfaces.

Precision Shoulder: The unthreaded shoulder portion is sized perfectly to align the starter motor housing, ensuring the starter drive gear hits the flywheel ring gear at the correct angle.

Direct OE Specification: Replaces worn, stripped, or rusted original hardware with the exact dimensions required for 12V and 6V transmissions.

Technical Specifications Part Number: 111199101

Head Style: D-Shaped (Flat side)

Thread Pitch: M10 x 1.5

Finish: Zinc Plated or Black Oxide

Placement: Upper Right Engine-to-Transmission Connection

Installation & Maintenance Tips Check for Burrs: Before sliding the bolt through, inspect the transmission hole for burrs or debris. If the bolt is forced in, it can damage the D-recess in the aluminum case.

Clean the Ground: Since the starter motor relies on its physical connection to the transmission for a ground, ensure the bolt and the area around the starter mounting ear are clean and free of heavy paint or rust.

Anti-Seize Usage: Apply a small amount of anti-seize to the threads. This bolt is exposed to the elements under the car and is notorious for seizing over decades, making future engine removals difficult.

Don't Forget the Nut: This bolt requires a standard M10 x 1.5 nut and wave washer (sold separately) to secure the starter.
