Advantage:

• It is located at the back of the crankshaft and is responsible for sealing the interface between the crankshaft and the engine block, preventing oil from leaking out.
• If the rear oil seal becomes damaged, worn, or develops a leak, it can lead to oil leakage from the back of the engine. This can result in oil accumulation on the clutch, which can cause slipping or engagement issues. Additionally, excessive oil consumption may occur if the oil is leaking past the seal.
• If you are experiencing any of these symptoms with your Xinchai 490 engine, it is essential to have a qualified mechanic inspect the rear oil seal and replace it if necessary. Ignoring a faulty rear oil seal can lead to further engine damage and potentially costly repairs in the future.
