The ATC J-45393 Rear Crankshaft Seal Installer is a precision-engineered service tool designed to ensure accurate, damage-free installation of rear crankshaft oil seals on Mercedes-Benz MBE4000 diesel engines. This installer positions the seal squarely and evenly within the rear seal carrier, allowing technicians to achieve proper depth and alignment for long-term, leak-free operation.
Rear crankshaft seals are critical to engine oil control and clutch protection. Improper installation methods—such as uneven driving or improvised tools—can distort the seal lip or damage sealing surfaces, resulting in oil leaks and repeat repairs. The ATC J-45393 applies controlled, uniform pressure across the seal, helping prevent misalignment and ensuring consistent installation results.
Built for professional diesel technicians and engine rebuild environments, this tool supports efficient rear seal service during clutch replacement, in-frame repairs, and full engine overhauls.
