250 rpm control with hand throttle

[jhcattleco]

Im rigging up a 931a1 for a feed truck. I'm running into a problem keeping the rpms steady with a hand throttle. The engine wants to slowly wind to 2100 or if its set at 1500rpm like where we want to operate it as soon as the pto comes under load it moves down to 900 rpms and doesnt want to power the pto. Any advice?

You need a governor system for the fuel pump, like used on wreckers.

OR build a air throttle like I am doing, my 819 is missing the ip with the auxilary governor, and the hand throttle gives me the same problem, one thing, the 250 MUST be at operating temp to get the hand throttle to come even close to working right. You will have better luck controling accessory drive speed using a transfer case pto.

do you know where I could find more info, I looked thru the tech manuals on the inj pump and saw a picture of a vs governor but not much info. is it a bolt on part? I just need to know what all i need and how its going to work.
Thanks
