Good Morning - I have been offered an AC 66 combine. The task is to create a complete unit out of 2 parts machines sitting outside and a complete combine that"s down to nuts and bolts in a barn. I"m a non-recovering addict (sucker) for something like this and old machinery in general. My question for the masses is does a service manual or set-up manual exist for these machines? I have parts and ops manuals, I"m trying to do it once, and get it right where clearances and alignments are concerned, instead of doing the same pieces over and over as the various sections go together. Maybe I"m over thinking this, any opinions?
