The ATC 4918798 Front Seal & Wear Sleeve Remover and Installer is a precision service tool designed to remove and install front crankshaft oil seals and wear sleeves on Cummins ISM, L10, and M11 diesel engines. Engineered for professional use, this tool set enables technicians to service the front seal area accurately, safely, and without damage to the crankshaft or sealing components.
Front crankshaft seals and wear sleeves require exact alignment and controlled installation depth to prevent leaks. Improvised prying or driving methods can distort the seal, mis-seat the sleeve, or score the crankshaft sealing surface—often resulting in immediate oil leaks and repeat labor. The ATC 4918798 applies even, controlled force during both removal and installation, guiding components squarely and concentrically for reliable, leak-free results.
Built for durability and repeat use, this tool is ideal for diesel repair shops, fleet maintenance operations, and engine rebuild facilities performing front-end service during in-frame repairs, accessory drive work, or complete overhauls.
