Does anyone know an easy way to remove the LW-14260 oil seal from the tach drive shaft with the engine still mounted in the plane? Is there a special tool I can make or buy to make the job easier rather than just the "rough"old way There is not much room around it to try to pry it out with something and the edge of the seal has a metal casing making it difficult to get behind it. Some type of puller perhaps? Any ideas ?
