Detailed Description

This SKF Speedi-Sleeve is engineered to restore the sealing area on a worn crankshaft quickly and cleanly. Instead of regrinding the shaft, the sleeve creates a new outer sealing surface that supports reliable rear main seal contact. For technicians servicing a Ford Ranger rear crankshaft repair or a Mazda B2200 rear seal repair, SKF 99399 provides a direct repair path when the original shaft surface is no longer smooth.

This part cross-references 6353829 and 12328975 for the same application.

What It Helps Fix

• Grooved or scored crankshaft sealing surfaces
• Rear main seal leakage caused by shaft wear
• Time-consuming shaft regrinding during engine service
• Seal wear from an uneven crankshaft contact area
• Repeat rear seal failure after prior repairs

Installation Notes and Tips

Clean the shaft thoroughly before installation and verify the 4.000-inch diameter before ordering. The sleeve is designed to be installed over the existing shaft surface, and the included tool helps seat it correctly. For best results, inspect the rear seal area for additional wear before final assembly on 1982-1984 Mazda B2200 and 1983-1984 Ford Ranger engines.
