IH 504U problem

I ran into a problem with my IH504 utility yesterday that I was hoping I could get some help with. While operating the tractor the machine suddenly lost throttle response. The RPM's dropped to idle and couldn't be increased unless someone manually moved the throttle linkage on the carb. Upon inspection, the throttle linkage to the governor (I believe it's the governor anyhow, I haven't had much experience working on that) would move just fine. That linkage runs on the right side of the tractor (if you are in the seat facing forward). However, the linkage from the governor to the carb thottle linkage won't move when the throttle lever is pushed or pulled. That linkage looks like it runs from the right side of the tractor under the crankshaft pulley to the left side where it hooks up to the main throttle linkage to the carburetor.

Has anyone else had this problem? Is it an easy fix or will the governor have to be replaced? I might get some quality wrench time on this little project because it looks like I might have to take off the radiator and fan shroud just to get to the working area.

Thanks a lot for any help,
Chad

It sounds like your governor spring broke.If it breaks you won't be able to get any engine RPM above a low idle.

What all is involved in fixing it? I just got in from putting out a roundbale and mine just did the same thing. Had to putt back into the barn at idle. Only mine is the Farmall row crop

The governor spring is inside the governor on that tractor.Unhook both linkages and unbolt the governor its not timed to anything.Once you get it off and look inside it should be self explanitory.The part number for that spring is 369686R2.

I made a mistake.I believe the governor gear also drives the distributer on that model tractor.Set the engine on top dead center #1 compression stroke before removing governor.I'm sorry for the missinformation.
