Description
Overview:
This crankshaft oil seal is a non-genuine replacement for Yanmar single-cylinder diesel engines, sized to suit the L75 and L90, with the same fitment also used on the L100 family. It is made from an oil-resistant elastomer with steel reinforcement and a spring-loaded sealing lip for steady contact on the crank journal. The seal prevents engine oil leakage and helps keep dirt out, protecting bearings and extending service life across compact construction and garden machinery. Nominal size: 35 x 50 x 10 mm (1.38 x 1.97 x 0.39 in). It replaces OEM reference 24423-355008 and is identified by MPN 320 208. Suitable for the relevant crankshaft location as specified by the equipment manufacturer.
