Hi;
I also am rebuilding an oc-3. the motor that came out of mine is a hercules IXB, which has 3.250" bore and a 4" stroke. it sounds like you have the right motor.
good luck

The military engines are different on the inside. Is the one you looked at have 3 timing gears (IXB-3) or 5 (IXB-5). Cletrac did not use the IXB-5, The goverment did. They also had some IXB-3 engines. Military engines take military standard parts bearing are the big ones in your case, but most of those military engines do not have many hours on them Questions?
John, are the military IXB-5's the same as the IXB-5's used in Leader and other tractors?
Hello, When I looked at this engine ,it was still in the machine, and I couldnt see it very well. What I could make out on the tag,looked like IXI-B3,does anyone know whether this engine has the same flywheel and bell housing pattern as a IXB ? Is this the same on the outside as a IXB? Any information about this engine will be apreciated thanks,kevin
Blake: I am not sure how I want to answer that. Are you talking looking at it externally or at the internal parts?
Either one John... I just wondered if there was a difference.
