In the process of the repair work on my 955H I found two great sources.
The first for manuals. http://www.jensales.com. They have reproduction manuals. My 955 traxcavator service manual was in stock!
The second is Machinery Parts Midwest. His site is hard to navigate But if you call him he is very knowledgeable, helpful and friendly. There is already a link here but I will post it againhttp://www.angelfire.com/mo3/ameritractor/home.htmlHope these are helpful.
