Super C Govenor

What should I check for?

Are there any adjustments on the govenor and where?

I am unclear on exactly what you checked when you checked the governor. You are looking for RESISTANCE, not range of motion. The governor should feel like it is fighting you.

Check the resistance to motion with the engine off, then again with the engine running. You should feel much more resistance with it running.

Try to find a good running C or other letter-series Farmall in your neighborhood (shouldn"t be too hard) and compare the feel of that governor to yours.

As for adjustment: you can set the low and high idle speeds (limits), and there is also an adjustment for "hunting," where the governor can"t seem to make up it"s mind where to set the speed.

If I understand your problem, though, the governor is not "hunting," the tractor does not stall out at idle and reaches a pretty good RPM, so I would not start monkeying with adjustments until you have checked the governor for proper operation.

Rebuild kits are available. You want to get a copy of the IT IH-8 manual and read the procedure first. You can also get an Owner"s Manual reprint from Case. Unless you are VERY familiar with the Super C I strongly suggest you get a copy and read it cover to cover, like a novel.

My Super C has never had the governor rebuilt and I think I am beginning to feel the first signs of wear (stumbles ever so slightly when comming up from a slow idle), so I would appreciate you keeping me posted if you decide a rebuild is necessary.

Good luck! Go Whompus Cats!

How do I set the idle and ful speed linkage?

But if the governor isn't working right, you will be wasting time.

Worse; if the clevis is properly adjusted on the throttle rod, and you mess with the adjustments NOW, you will screw them up and have to reset them when the governor is restored to correct operation. (Fortunately this doesn't take too long.)

Don't take my word for it; the IT manual contains the following warning, printed in italics FOR EMPHASIS!

"Before attempting any governor adjustments, check the linkage for binding condition or lost motion and correct any undesirable conditions."

Lack of resistance is the most undesirable governor condition of all! The governer works by conservation of momentum. No resistance, no conservation!

So, once more, PLEASE grab the throttle rod coming from the carburetor with the engine off and work it through its range. You should feel very, very little resistance.

Now, start the engine. Grab the throttle rod again and try to rev the engine. You should feel greatly increased resistance.

If this resistance is not present attempting to adjust the governor is a waste of time. I cannot emphasize this enough.

AFTER you have determined the governor is operating properly, shut the engine down.

Move the speed control lever all the way to the high end of it's range. Remove the pin from the clevis.

Now, hold the throttle rod and the rockshaft arm (the other piece of the assembly the pin hold the clevis onto) as far forward as they go.

The pins should slide easily home. If not, turn the clevis on the threaded part of the rod until they do.

(If I ever bet, which I don't I would bet fifty dollars that they will. Because I think the governor IS properly adjusted.)

Now, to set the high speed idle: simply adjust the hex screw coming out of the top of the housing.

That's all there is to it. But please, please, PLEASE, if you haven't done it, check the governor for proper resistance to motion before you do.

High speed idle: 1875 RPM

These numbers are not critical, especially the low speed idle. But you probably already knew that.
