Some time ago, the Wisconsin Historical Society received two boxes of Microfilm from Case-IH that contained early tractor parts drawings. With some major financial assistance from Chet Krause, the microfilm was scanned and is now available digitally.
We confirmed today that there are also some engineering drawings for certain IH stationary engines as well. It looks like there are SOME (not all) drawings available for parts for:
Titan Sideshaft engines (includng some sizes that never made it into production)
What happened is this: in the 1950s, when the engine and tractor operations were seperated, the IH folks seperated the parts drawings by prefix- all the G numbers went to the engine operations, all the T and D numbers went to the tractor folks. Of course, most of the parts for the above mentioned engines were Ts, so they were thrown in with the tractors!
