1950 H Throttle Connection

Moki · Mar 6, 2011

We overhauled this H because it was smoking a little and probably from sitting too much. It was my uncle's tractor, bought new in 1951 and never used much. I was having trouble with surging after the overhaul but think I have now solved that problem with your help. Next question: I don't seem to have the full range of the throttle quadrant and the springs on the end of the throttle shaft where it attaches to the governor shaft seem loose. Can I shim them up with washers or should I get new springs or is there something else going on that you know of? This tractor was hardly ever used and the drawbar hole isn't even worn out of shape. I think we just didn't get it back together quite right or else the springs are weak from age. Ideas? Thanks! Moki

I just used a washer as a shim at each spring. It worked well for me.

good luck

Shim them till they have a little compression. Make sure the hand throttle lever pulls the governor lever all the way to its max position when wide open. If it does not it will run slower than spec. The governor will limit max rpm. Search for From a prior post on this topic:
The rod from the hand throttle has the governor control equalizer (U shaped metal) that slips on first, then one spring then the governor control pivot, then the other spring, then the last flange of the equalizer. The nut holds the equalizer in position, and is tightened to do so. The springs keep the sliding pivot centered. If the springs are week, putting washers on either side of them can center the pivot. The linkage should pull the governor rod to full limit of travel when in the rear notch of the hand lever, and all the way to the idle position when forward. Adjustment of this is usually not needed. if it is not going full travel when operated at the hand lever, washers could be used to move the pivot between the springs such that it does. In all cases the pivot should be between two springs. See diagram in caseih.com search for parts.

The '51 H I have is much like Jim describes below with one exception. There is another nut between the second spring and the equalizer bracket. It fills the gap after the second spring plus locks the equalizer to have a double-nut effect on the throttle rod.
