The M10050 Front & Rear Crankshaft Seal & Wear Sleeve Installer is a heavy-duty specialty tool engineered for use on the Caterpillar 3406, 3408 and C15 engine families. Specifically designed to install both front and rear crankshaft oil seals and wear sleeves, this tool kit restores proper sealing surfaces and ensures reliable rotation and sealing in high-performance diesel engines.
When rebuilding or servicing these engine blocks, misaligned or poorly seated crankshaft seals—or worn wear sleeves—can lead to oil leaks, crank bearing contamination, and excessive engine wear. The M10050 provides precision alignment and controlled installation of the wear sleeve and seal assembly, resulting in consistent performance, improved longevity and fewer re-seals.
