The M10236 Rear Wear Sleeve Installer is a precision-engineered service tool designed for installing rear crankshaft wear sleeves on Caterpillar 3176, 3196, C-10, and C-12 diesel engines. Built as a direct functional equivalent to Caterpillar OEM tool 147-2675, this installer ensures accurate, square seating of the wear sleeve on the crankshaft—an essential step for achieving a reliable rear main seal.
Rear wear sleeves provide a fresh sealing surface for the rear crankshaft seal. Improper installation—such as cocking the sleeve or driving it unevenly—can lead to oil leaks, premature seal failure, and costly comebacks. The M10236 applies even, controlled force to the sleeve, guiding it straight onto the crankshaft journal without damaging the sleeve, crankshaft, or seal mating surfaces.
Designed for professional diesel technicians, engine rebuild shops, and fleet maintenance facilities, the M10236 delivers repeatable, OEM-level results during rear main seal service and engine overhaul procedures.

Why It Matters
The rear crankshaft wear sleeve and seal work together to contain engine oil at the rear of the crankshaft. If the sleeve is installed incorrectly, even a new seal may leak. The M10236 Rear Wear Sleeve Installer ensures precise sleeve placement, supporting proper seal contact and helping technicians deliver long-lasting, leak-free repairs.
