Are you dealing with an oil leak at the front of your Cummins? The MAHLE 68130 Front Crankshaft Seal is the fix that stops the problem at its source, restoring a tight, reliable seal. Designed specifically for 6.7L Cummins applications, this seal keeps oil contained under pressure, preventing leaks that can quickly turn into lost oil and long-term engine issues.

Front crank seal leaks are one of those problems that only get worse over time, and once they start, they just keep getting worse. This is a direct-fit, OE-quality solution that restores proper sealing performance to your engine, whether you’re doing preventive maintenance or repairing an active leak. If you’re already in there, this is the part that prevents you from having to come back and redo the job.

MAHLE builds the 68130 to meet strict OEM specifications, ensuring proper fitment, sealing pressure, and long-term durability in high-heat diesel environments. It’s designed as a direct replacement for the factory seal, delivering OE form, fit, and function so installation is straightforward and reliable.

Constructed from high-quality sealing materials, this front crank seal is engineered to withstand constant rotation, heat cycling, and oil exposure without breaking down. The precision-molded design maintains consistent contact with the crankshaft surface, helping prevent leaks and ensuring long-term oil control, exactly what you want in a component that plays a critical role in engine longevity.
