Flywheel Housing Seal Ring
Mitsubishi FUSO®

The Flywheel Housing Seal Ring, also known as the Rear Main Seal, is a vital part of a commercial truck's engine. This seal is located at the back of the engine block and is responsible for preventing oil from leaking out of the engine's crankshaft. The Flywheel Housing Seal Ring is designed to withstand high temperatures and pressure, ensuring that the engine oil stays in the engine where it belongs. Without a properly functioning Flywheel Housing Seal Ring, a commercial truck's engine would experience oil leaks, which can lead to engine damage and decreased performance. This can be costly to repair and can cause downtime for the truck. Therefore, it is important to regularly inspect and replace the Flywheel Housing Seal Ring to ensure that the engine is running smoothly and efficiently.
