Crankshaft seal PROX 25x40x8mm — Manufacturer reference: 41.2-25098

An essential wear part to maintain engine sealing, this PROX crankshaft seal is installed on the crankshaft side to limit oil leaks and protect the engine shaft from dirt and water ingress. Designed for off-road use, it is suitable for lightweight motorcycles and cross models requiring a precise diameter.

• Brand: PROX — claimed American manufacturing

Before installation, check the condition of the seal seat and clean the shaft to avoid damaging the sealing lip. A light film of oil on the lip facilitates installation and extends the seal's lifespan. Replace the crankshaft seal as soon as you notice leaks or visible wear: it is a simple operation that prevents more extensive engine repairs.
