Detailed Description

This SKF Speedi-Sleeve restores a scored or worn shaft sealing area so the oil seal can run on a smooth new surface. Instead of regrinding or replacing the shaft, the sleeve installs quickly and creates a consistent sealing finish. For Chevrolet C3500, GMC K3500, and other heavy-duty GM truck applications, SKF 99233 provides a direct repair solution when the original sealing surface is no longer serviceable.

This part cross-references CHR 99233 for the same application.

What It Helps Repair

• Oil leakage from a worn timing cover sealing surface
• Grooves or scoring on the shaft where the seal rides
• Seal wear caused by an uneven shaft finish
• Time lost to shaft removal and machine rework
• Repeat leaks after a damaged sealing surface is reused

Installation Notes and Tips

• Measure the shaft carefully before installation; this sleeve is for a 2.330-inch diameter.
• Clean the sealing area thoroughly before fitting the sleeve.
• Use the supplied installation tool to seat the sleeve evenly.
• Confirm the seal contacts the new sleeve surface correctly after installation.
