I collect and restore antique machinery (Engines, Chainsaws, CRAWLERS). I post fairly often on the smokstak.com forums, especially concerning an ongoing Hit&Miss engine restoration and this summer on a recently completed Cat Sixty Restoration:

We also have another cat Sixty we hope to restore next summer, it is Caterpillar Diesel Conversion number TWO, it needs quite a bit of mechanical work on the under carriage and so it has been waiting while we finish other "short term" projects.
I also own a Cletrac HG 42 that has been previously re-powered with a Allis Chalmers B125 power pack. It is also outfitted with a home-made dozer blade that needs some attention (currently it has a manual pump ram that only goes up, no down pressure)

But the reason for my deciding to post: I have a Cletrac 20C basket case (literally the engine came in baskets) that was imparted to me... the engine requires a good deal of machine work (two sleeves, valve seats) none of that is an issue. What is an issue has been locating a quality manual for the Hercules OOC engine, I have purchased the jensales manuals, but their quality was less than stellar. I was wondering if anyone knew of a Hercules over-haul manual or all inclusive Hercules manual?
