    Shaft Seal, crankshaft

      The Shaft Seal, crankshaft (20033889B) seals engine oil at the crankshaft exit point. Replacing it with a Porza-quality seal restores oil retention, engine protection, and long-term reliability.  

    FAQ

    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.

    Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.

    Porza provides high-quality sealing components with fast delivery across Europe and options for online ordering or in-store pickup.

    If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
