Engine Timing Cover Repair Sleeve

SKF 99186 is a timing cover repair sleeve for restoring a worn shaft sealing surface without removing the shaft. It is sized for a 1.869-inch shaft diameter and is engineered to help return the sealing area to a smooth, usable condition.

Key Features

• Restores a worn sealing surface without shaft removal.
• Maintains the original seal size during installation.
• Made from AISI 304 stainless steel for corrosion resistance and durability.
• Includes an installation tool for proper sleeve placement.
• Fits a wide range of classic Buick, Pontiac, and Oldsmobile applications.

Detailed Description

SKF Speedi-Sleeve 99186 is built for applications where the shaft surface has become scored or worn and a new sealing surface is needed. Instead of regrinding or replacing the shaft, this repair sleeve provides a precise outer surface for the seal to run against. The 99186 part number is associated with a 1.869-inch shaft diameter, and the stainless-steel construction supports consistent sealing performance in repair work. This part cross-references Monroe Shocks & Struts (e.g., 145899186, 975999186) for the same application. Compatible with classic Buick, Pontiac, and Oldsmobile engine repair needs, SKF 99186 is a practical solution when the original sealing area has deteriorated.

What It Is Used For

• Scored or grooved shaft sealing surfaces.
• Oil leakage caused by wear at the seal contact area.
• Repair jobs where shaft removal is not practical.
• Restoring a smooth sealing track after surface damage.
• Reducing the need for shaft regrinding or refinishing.

Installation Notes and Tips

Confirm the shaft diameter before installation to ensure the sleeve matches the application. The sleeve installs over the existing shaft and does not require a change in seal size. Use the supplied installation tool to seat the sleeve correctly and avoid damaging the sealing surface during assembly.
