    Default IH 656 Horsepower Increase

    I was talking to a friend recently who had recently rebuilt the motor on his 656 and in the process bumped the hp up to about 90 (He figured) by simply adjusting a screw or something on the injector pump. Does this seem reasonable? Is there such a procedure? Our 656 is due for a rebuild and I was wondering about this.

    Thanks

    You might want to try the Farmall/IHC forum at www.ytmag.com. Those "red" guys are an extremely knowledgeable and helpful bunch...

    Good luck.

    yeah that is possible on those old farmalls. When we where farming we had a 656, 856, and 1456 and we had the injection pumps cranked on all of them.

    That is interesting to know. I wonder if you could do that to a 504?
