YANMAR B12 gearbox duo-cone seal

A high-quality seal is a complete set to prevent oil leaks at the connection point of the reduction gear flange and the travel final drive. The kit consists of a metal ring, a rubber O-ring and a brown ring. The metal ring together with the outer race of the bearing form the so-called sliding seal that allows the component to rotate and its tightness. The rubber O-ring prevents oil leakage on the housing side and acts as a shock absorber to prevent damage to the ring under stress
