This seal was made to be replaced when the engine cases are split! It can be replaced without splitting the cases but it is tricky to drive it in intact. We suggest riders purchase more than one as you will need another again someday if not right away if you do not succeed in replacing the seal intact. We suggest you also clean and polish your clutch pushrod as grit & nicks on the rod will saw away at the seal lip causing early wear. Part #01-9019 $4.85 Pc.
