The M20147‑A Rear Crankshaft Seal Remover & Installer Kit is a precision service tool kit designed specifically for Cummins ISX and QSX engine families and serves as the direct replacement for OEM part number 3164780. This kit enables technicians and rebuild professionals to safely remove and install the rear crankshaft oil seal (and associated wear sleeve) with OEM-level accuracy in heavy-duty diesel applications.
Crafted for heavy-duty service shops, remanufacturers, and fleet maintenance facilities, the M20147-A includes all necessary components for proper alignment, extraction, and installation. By using this tool set, you reduce the risk of seal lip damage, crankshaft surface scoring, improper seating, and premature leakage—common issues when attempting seal service without the correct tooling. The kit supports efficient turnaround, ensures repeatable results, and helps maintain seal integrity and durability in high-duty applications.
