A seal for a flywheel, commonly known as a rear main seal or crankshaft seal, is a sealing component located between the engine and the flywheel. Its function is to prevent engine oil from leaking out at the rear of the crankshaft while maintaining proper lubrication inside the engine.
Key specifications include inner and outer diameter, sealing lip design (single or double lip), and material type. Flywheel seals are typically made from oil-resistant materials such as nitrile rubber (NBR) or fluorocarbon (FKM/Viton). They must withstand rotational motion, oil exposure, pressure, and temperatures typically ranging from -40°C to +150°C.
Replacement is necessary when there are signs of oil leakage at the rear of the engine or when the seal becomes worn, hardened, or damaged. It is also recommended to replace the seal during clutch or flywheel service, as access requires removal of the transmission.
