A high-quality rear crankshaft oil seal. It is a key engine sealing component, responsible for preventing engine oil leaks between the rotating crankshaft and the engine block. Made of a material resistant to high temperatures and oils, with a garter spring and an additional dust lip (BASL), it ensures maximum sealing and protection against contaminants.
GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

The list above is for reference. It is key to match the seal to the specific engine model.
The rear crankshaft seal prevents oil leaks from the engine where the crankshaft connects to the flywheel. Its failure is a serious fault that can lead to contamination of the clutch, resulting in its slipping and burning out.
A leaking crankshaft seal can destroy your clutch.
Replacing a rear seal is a major job that requires removing the transmission or engine. If you're already doing this work, don't risk having to do it again in a few months. Invest in peace of mind – order a high-quality GX-AFTER seal and ensure leak-free operation for years to come.

BASL is a designation for the seal's construction. It means that in addition to the main sealing lip (with a spring), it has an additional, outer dust lip. It protects the main lip from dust and dirt, which significantly extends the seal's service life.
2. I replaced the seal, and it's still leaking. What could be the cause?The most common causes are damage to the seal during installation (e.g., pressing it in at an angle), a worn groove on the crankshaft surface, or excessive pressure in the engine crankcase (e.g., due to a clogged breather).
3. Can I install this seal on the front of the engine?No. Although the front and rear seals may look similar, they often differ in dimensions and the direction of the sealing lip's operation (if the shaft is helical). You should always use a seal dedicated to the specific location on the engine.
