Key Features

• Precision-engineered stainless steel sleeve with hard chrome finish for extended service life
• Thin-wall design preserves the original seal size and sealing geometry
• No expensive preparation or machining required before installation
• Removable installation flange helps reduce sleeve distortion during mounting
• Includes its own installation tool for shaft installation without removal

Detailed Description

Kwik-Sleeves are used to restore a worn sealing surface on shafts that have been damaged by age, mileage, or seal wear. Timken KWK99354 creates a smooth, durable surface that supports reliable lip-seal contact, making it a practical repair solution for manual transmission output shafts and differential pinions. This part cross-references SKF (e.g., 99354) for the same application. Common fitment includes Porsche 911, BMW 528i, BMW X5, and Saab 9-5 applications, along with many other rear and front driveline uses.

What This Part Helps Address

• Oil leakage caused by a grooved or worn shaft sealing surface
• Seal failure after repeated contact with a damaged shaft
• Repair needs where machining or shaft replacement is not practical
• Restoration of lip-seal contact on manual transmission output shafts
• Wear at differential pinion sealing areas

Installation Notes and Tips

• Clean the shaft thoroughly before installation and inspect for deep scoring or structural damage.
• Use the supplied installation tool and removable flange to help keep the sleeve aligned during mounting.
• The thin-wall sleeve is engineered to work without changing seal size, which helps maintain the original sealing setup.
