This high-quality component is made for use with walk-behind rotor tillers. It is an authentic oil seal which is supplied by the original equipment manufacturer. This item helps to provide a tight seal for the ball bearing and the transmission shaft. Over time it may wear out and begin to crack eventually requiring a replacement to prevent oil leaks. For the exact location and the correct installation check the diagrams of your model. This high-quality oil seal is made of a durable rubber material with a metal casing and is sold as an individual component. You will need wrench set and a tool to pull off the old seal when performing this repair.
