Description

Don’t Risk the Leak. Do It Right the First Time.

The Rear Main Seal (RMS) on the Porsche 9A1 (MA1) engine is unforgiving. Unlike older engines, the MA1 requires the seal to be set to a precise, non-standard depth relative to the crankshaft flange. Installing it “flush” or tapping it in by hand is a guaranteed recipe for an oil leak, forcing you to drop the transmission all over again.

Our MA1/9A1 RMS Installer Tool eliminates the guesswork. Designed to replicate the factory service tool’s precision at a fraction of the cost, this tool presses the seal in evenly, squarely, and to the exact factory-specified depth every single time.

Key Features & Benefits

• Precision Depth Control: The tool features a built-in “hard stop” that sets the seal to the exact factory specification (typically 6.5mm recessed depth for MA1 engines). You cannot push it in too deep.

• Self-Centering Design: The tool pilots directly onto the crankshaft hub, ensuring the seal enters the bore perfectly square. This prevents “cocking,” which damages the delicate PTFE sealing lip.

• Engine-Safe Construction: Machined from high-strength, billet aluminum . It is tough enough to press the seal but soft enough to ensure no damage occurs to the sensitive crankshaft sealing surface.

• Uses Factory Hardware: No hydraulic presses or complex adapters needed. The tool is designed to be pressed in using your existing flywheel bolts. simply tighten them in a star pattern until the tool bottoms out.

Why You Need This Tool

• Eliminate “Do-Over” Anxiety: The RMS is a PTFE (Teflon) seal. Once installed, it cannot be adjusted or removed without destroying it. This tool ensures it is right on the first try.

• Professional Results: Mimics the function of the expensive dealer tool (OEM #9699/3) used by Porsche technicians.

• Cost Effective: Pays for itself by preventing a single ruined seal or the labor cost of a re-do.
