SKF 99346 Engine Crankshaft Repair Sleeve - Rear

SKF 99346 Crankshaft Repair Sleeve

SKF 99346 is an engine crankshaft repair sleeve for a 3.500-inch shaft diameter. It restores a worn sealing surface without removing the shaft, making it a practical solution for rear seal repair on select Toyota applications.

Key Features

• 3.500-inch shaft diameter for the specified crankshaft surface
• Engineered from AISI 304 stainless steel for corrosion resistance and durability
• Installs without shaft removal and without changing seal size
• Provides a smooth outer sealing surface for rear main seal contact
• Includes an installation tool for proper sleeve placement

Application Details

Compatible with rear crankshaft repair needs on 1995-2015 Toyota Tacoma, 2010 Toyota 4Runner, 1996-2000 Toyota 4Runner, and 1994-1998 Toyota T100. This part cross-references CHR 99346 for the same application. The SKF 99346 sleeve is used to renew a scored or worn crankshaft sealing area so the rear seal can run on a restored surface instead of damaged metal.

Common Problems It Can Solve

• Rear main seal leakage caused by a grooved crankshaft surface
• Oil seepage from wear at the seal contact area
• Seal failure after repeated contact with a scored shaft
• Need for shaft refinishing when regrinding is not preferred
• Restoration of the sealing surface on Toyota Tacoma, 4Runner, and T100 rear applications

Installation Notes

Clean the shaft thoroughly before installation and verify the 3.500-inch diameter before ordering. The sleeve is designed to install over the existing shaft surface, which helps avoid shaft removal and keeps the original seal size unchanged. Use the supplied installation tool to seat the sleeve evenly and prevent distortion during installation.
