Detailed Description

SKF 99086 is a manual transmission input shaft repair sleeve designed to restore the sealing surface on shafts that have become scored or worn. It is a practical solution when the original shaft diameter is 0.859 in. and the sealing area needs to be returned to a smooth finish for reliable seal contact. This part is especially relevant for 1965-1969 Porsche 911 manual transmission service, where a worn input shaft can affect sealing performance and lead to repeat repairs.

Built from AISI 304 stainless steel, the sleeve provides a consistent outer surface for the seal to ride on. SKF 99086 is intended for repair work where regrinding is not desirable, and it supports a faster service process on Porsche 911 applications from 1965 through 1969.

Vehicle Fitment

• Fits 1965-1969 Porsche 911, N/A

What It Helps Fix

• Scored or grooved transmission input shaft sealing surfaces
• Oil leakage at the input shaft seal area
• Seal wear caused by an uneven shaft finish
• Time-consuming shaft regrinding during transmission repair
• Repeat leaks after seal replacement on worn shafts

Installation Notes and Tips

Clean the shaft thoroughly before installation and verify the shaft diameter is 0.859 in. before selecting this sleeve. The sleeve is installed directly on the shaft, and the included tool helps position it correctly for a uniform sealing surface. For Porsche 911 manual transmission service, confirm the repair area is free of burrs, heavy scoring, or contamination before assembly.
