Just added several Cleveland factory internal documents, including specifications for the experimental X-12, and specifications and comparisons with competitors for OC-3, OC-4, OC-6 dozers, OC-9, OC-96, and OC-12 loader to the MANUALS & LITERATURE page at http://cletrac.org/pages/manuals.html
Also added Roosa-Master injection pump assembly and disassembly instructions. And much more!
Check often as more is added as time permits.

I just uploaded an OC-3 4-page brochure with specifications, and an Imp Loader for the OC-3 2-page brochure. These are on the Manuals & Literature page of the Cletrac site.
