images and then digitally cleaned page by page. Packed with invaluable data including many Photographs, diagrams and Tables (See detailed contents list below). These engines were used by the US Airforce as Ground Power Units for large aircraft and as portable generators. In the 1960’s and 1970’s many homebuilders converted these now surplus units as economical engines for homebuilt aircraft. The first manual was published under the secretary of the Airforce in September 1950 with revisions to November 1951 and reprinted in 1954. It Contains 2 manuals in one. The first being T.O. (Technical Order) 19-45-90 the Overhaul Manual and T.O. 19-45-91 being the Illustrated Parts Catalog and totals 90 pages.
The third manual is a private work compiled by Donald Pridham in 1970 and details his research into the O-290-G and its conversion to an O-290-D to enable its use in aircraft and runs to 205 pages in total.
Also included on the CD is an Adobe Acrobat version of the manuals for easy browsing (Adobe Reader 7.0 supplied on the CD). Comes in a nicely printed Jewel case. See my other auctions for more vintage aircraft and engine manuals.
