Two Words wtf......"Service Manual".....OEM preferred....OK so that's four words....

Get one and read it. It'll take you through the process of rebuild and what to do and look for. A parts manual would be of great value also.

Search up Ken Cook Co. They sell the reprints of the manuals and sell on line. Have your model number handy.

Any questions you may have you can post here. Keep us up to date on the progress.
