Elring 742.950 Crankshaft Seal Overview

The Elring 742.950 engine crankshaft seal is a radial shaft seal built for precise sealing at the crankshaft. It uses FPM (fluoride rubber) for heat and fluid resistance, along with a dust lip to help keep contaminants out of the sealing area. This seal is a direct-fit option for select Mercedes-Benz diesel applications, including Sprinter 2500, Sprinter 3500, E250, GLK250, and ML250 models.

This part cross-references Mercedes-Benz OE numbers 014 997 26 46 and A 014 997 51 46 for the same application.

Installation Notes and Tips

Verify the seal dimensions before installation: 60.0 mm inside diameter, 75.0 mm outside diameter, and 8.0 mm thickness. Confirm the swirl direction and dust lip orientation match the original part on the vehicle. For best results, inspect the crankshaft sealing surface for scoring, contamination, or wear before installing the new seal.
