Part: 5.9/6.7 C OE REAR MAIN CRANK SEAL W/ SLEEVE 89-18
Part Number: 3926126
Manufacturer: Cummins
Description:
This Cummins part is the Rear Main Crankshaft Seal with Sleeve designed for 5.9L and 6.7L Cummins engines manufactured between 1989 and 2018. This seal is a critical component in preventing oil leaks from the rear of the crankshaft, where it exits the engine block.
This seal prevents engine oil from leaking out around the rear of the crankshaft. The rear main seal is located at the back of the engine block, sealing the area where the crankshaft exits the block. The sleeve is typically used to restore the surface finish of the crankshaft, which can become worn or scored over time. The seal and sleeve work together to ensure a tight, reliable seal to prevent oil leaks.
The rear main seal is typically made from rubber or elastomeric materials, while the sleeve is usually made of steel or a durable metal that can withstand the high pressures and temperatures within the engine.
This seal is specifically designed for Cummins 5.9L and 6.7L engines. These engines are commonly found in light-duty trucks (such as the Dodge Ram), medium-duty trucks, industrial equipment, and generators. It is an OE (Original Equipment) part, ensuring proper fitment and function.
Building engines the way the OEM factory should have in the first place.
