Diagram Ref No 21 

Providing an alternative to the Genuine Porsche component, this seal helps prevent gearbox oil escaping around the driveshaft output, maintaining correct transmission lubrication.

What Does It Do?

The driveshaft oil seal fits between the rotating output shaft and the transmission housing, creating an oil-tight barrier.

It retains gearbox fluid while helping prevent road dirt, moisture and other contaminants entering the transmission.

Why Is It Important?

A secure driveshaft seal helps maintain the correct oil level and protects internal gearbox components.

A worn or leaking seal may lead to:

• Oil leaks around the driveshaft flange
• Reduced PDK transmission oil levels
• Oil residue beneath the gearbox
• Increased risk of transmission wear

Why Does It Fail?

Typical causes include:

• Rubber hardening through age and heat
• Normal wear of the sealing lip
• Damage during driveshaft removal
• Worn or scratched shaft surfaces
• Incorrect installation

When Should It Be Replaced?

Replace the seal if oil leakage is visible around the gearbox output shaft or if the seal is cracked, hardened or damaged.

It should also be inspected during driveshaft removal or transmission servicing.

Checks & Installation

Clean and inspect the output shaft and seal housing before fitting.

Install the replacement seal evenly using suitable tools, avoiding damage to the sealing lip.

Check the transmission oil level after installation using the correct Porsche procedure.

Porsche 718 & 991.2 PDK Gearbox Oil Seals
