A shaft seal for a crankshaft is a sealing component installed at the front or rear of the crankshaft. Its function is to prevent engine oil from leaking out and to keep contaminants from entering the engine.
Key specifications include inner and outer diameter, thickness, material type (such as NBR or FKM), temperature resistance, and compatibility with the engine. It must withstand rotation, pressure, and exposure to oil.
Replacement is necessary when the seal is worn, hardened, or leaking. Common symptoms include oil leaks at the front or rear of the engine, oil contamination, or reduced engine efficiency.
