ME151039
Crankshaft O-Ring
Mitsubishi FUSO®

The Crankshaft O-Ring, also known as ME151039, is a small but crucial component of a truck's engine. It is a circular ring made of rubber or other flexible materials that is placed in the grooves of the crankshaft to prevent oil from leaking out. The O-ring creates a tight seal between the crankshaft and the engine block, ensuring that oil circulates smoothly throughout the engine and does not escape. A damaged or worn Crankshaft O-ring can lead to oil leaks, decreased engine performance, and even engine failure. As such, it is important to regularly inspect and replace this component as needed to maintain optimal engine function.
