This is the crankshaft seal carrier centering guide for use on the Cummins ISB. This is a direct replacement to part # 5395409
The M20196 Crankshaft Seal Carrier Centering Guide is a precision alignment tool engineered for servicing Cummins ISB engines using seal carrier group replaces Cummins 5395409. This specialized guide ensures that the rear or front crankshaft seal carrier is installed in perfect concentric alignment with the crankshaft—a critical requirement for preventing premature seal wear, oil leakage, and shaft scoring.
During seal replacement or carrier installation, even slight misalignment can cause immediate sealing failure. The M20196 eliminates guesswork by positioning the seal carrier accurately over the crankshaft journal, ensuring proper seal seating depth, uniform lip contact, and long-term reliability. This tool is essential for technicians performing in-frame repairs, seal service, or complete overhauls on ISB-powered trucks, buses, agricultural machinery, and industrial equipment.
Built from durable, shop-grade materials, the M20196 provides consistent results in high-volume diesel maintenance environments. It is compatible with Cummins ISB 6.7 platforms and any application utilizing the 5395409 carrier assembly.
