Surging govenor

d282 · Jun 24, 2013

When I use my 460 for medium duty jobs like grinding feed, hauling wagons or bailing hay the engine likes to surge. If I use it to plow the engine holds steady. My dad says this is how all 460's are. Is there something I can do to keep it from surging?
Thanks

The idle mixture could be too lean.

Gas or diesel? If gas, you have a governor issue. If diesel, the problem is in the diesel injection pump.

You dad is incorrect. That 460 should run smooth as silk at ALL engine speeds and ALL loads.

sorry----Gas

I'd go for carb adjustment, too. First time I ground feed with my M it surged badly. While it was grinding I adjusted it - smooth as silk now. The letter tractors like it a little rich, but I think that still sounds like it is lean. You know how they get right when they run out of gas or you haven't turned on the tap? That's what you are dealing with.

Might be just carb is lean or rich, if it clears up when pulling hard like plowing maybe its a bit rich? Like said also, I would get it into the surging mode while grinding feed and adjust to see if it clears up.

Could also be a broken surge control spring or needs adjustment. Most original 460 governors were not very sensitive and it was unusual for one to surge. When they finally got a good governor in the 656 they would surge if not adjusted correctly. I am assuming all linkage to carburetor are in good shape and adjusted correctly.

from the IH book dated 6-20-58 - with the engine thoroughly warm, turn off. Close the [top needle] idle adjusting screw to its seat; then open one turn. The [bottom adj. screw] main fuel adjusting screw can be used to reduce the amount of fuel going into the engine when under light load conditions. However, when heavy work is to be performed in which the FULL POWER of the engine IS REQUIRED, the fuel adjusting screw should be set five turns off its seat. With the engine running at fast idle, turn in the throttle stop screw a few turns to prevent the engine from stopping when the throttle is closed. Start engine, close the throttle by pushing the engine speed control lever all the way up. [I like the way they worded that.] The throttle stop screw can be backed out until the desired idle speed (approximately 425 r.p.m.) is obtained. If the engine misses or rolls, the idle adjusting screw may be adjusted either in or out until the engine operates smoothly.

Hope this helps.
