NAPA or any local parts store will have the seal. (CR #11055) Stuart is right, you should pull it apart and at least clean it out and adjust it. They are simple to work on, and getting rebuild kits is pretty easy. Most vender's sell them. You can also go to your local bearing supply house and get what you need for a lot less money. Just take your old bushings and roller balls with you. The gaskets can be made very easy to. You will want to make a new seal for the 3/4" diameter input shaft as well. They are just leather so you cut a new one or just install a o-ring under the cap. It just needs something to keep dirt and water out of the gear box. Joe
