Common Issues This Seal Can Address

• Transmission fluid seepage at the main shaft sealing point
• Oil leakage around the gearshift linkage area on applicable Porsche 911 models
• Seal wear caused by age, heat, and fluid exposure
• Loss of sealing integrity from a hardened or damaged original seal
• Service replacement during manual transmission maintenance

Installation Notes and Tips

Verify the shaft diameter and seal dimensions before installation: 16.0 mm inside diameter, 24.0 mm outside diameter, and 7.5 mm thickness. Inspect the shaft surface and housing for wear, scoring, or contamination before fitting the new seal. Clean the sealing bore thoroughly and install the seal squarely to avoid distortion. Confirm the application notes for your Porsche 911, especially the gearshift linkage references on select model years.
