SKF Bearings Speedi-Sleeves
SKF Bearings Speedi-Sleeves save time and money in your manual transmission maintenance. No shaft disassembly or machining! These thin-walled shaft repair sleeves are simply pushed in position over the worn area, providing a counterface surface that is optimized for radial shaft seals. Since the same sized seal as the original can be used, there's no need to search for other seals or to keep a stock of different sizes. No special equipment is required since the installation tool is supplied with the Speedi-Sleeves. A mallet and a pair of pliers are all you need for the installation. These replacement parts use a proprietary stainless steel material and manufacturing process, resulting in an optimized seal counterface surface that minimizes wear on both sleeve and sealing lip. The proprietary material provides increased strength and excellent ductility properties of the sleeve. Imperceptible lubricant pockets enable the lubricant to reside on the sleeve and thereby prevent dry running of the sealing lip that otherwise can create excessive wear. Order the size recommended for your vehicle and transmission application.
