8N Governor Problem

I am in the final stages of reconditioning my 1948 8N. The engine has no serial number, but there was an aluminum plate braded to the top of the bell housing, that isunreadable due to age and excessive heat. It is possible that this engine was an industrial engine, moved over to my tractor by a former owner. I do have the year 1948 cast in the left rear axle housing, and a front mount distributor.

The engine governor is my problem. It is unlike the governors shown in the I&T FO-4 manual. Mine has an adjusting bolt with lock nut in the center of the housing. This adjustment bolt applies tention to a U shaped spring (internally) that inturn applies tension to the throttle lever (the outer lever). For more identification information, there is no proofmeter connection on this governor.

My problem is: Too much throttle when the hand throttle lever is in the last positon (Idle position). I can't get the throttle lever on the governor to relax to the idle position. It seems to always have tension on it wanting to increase engine speed. And, there is no adjustment on the governor to carburator linkage, so I can't adjust the linkage. It is a solid steel rod with no threads like the hand throttle to governor linkage.

my questions are:

1. Has anyone seen this style of governor, and do you understand this style of governor?

2. Where do I find printed information on this style of governor?

If I can't find printed information on this style:

3. How do I adjust this governor to allow the engine to idle, and to operate properly through the range of hand throttle settings?

Thanks in advance for your help on this.

That bolt and u-shaped springy do-hickey take the place and function of the IDLE set screw on the ARM of the governor shown in the FO-4. By screwing the bolt in, it puts tension on that u-shaped part and forces the fork towards the engine and the flyballs further in. In other words (now that I think about it) I guess IN means slower idle, and OUT lets the balls rest further out for a faster idle. If i'm wrong, it'll just be backwards.

I can't speak for any of the later model tractors, but that style was not used on the 9N/2N's and I don't think the 8N's used it either. I could be wrong about the 8N's, though. Seems likely that somebody robbed the governor you have off of another tractor and it was enough to get 'er back into the field. Governors don't go cheap, but if you can get one that's frozen up, you can just take the arm and housing and use your innards and go to town! Hope this has shed a littl light on it for you and if it was used somewhere else, others should chime in.

Good luck! BTW, you can use the same rebuild kit sold for the N-series on that governor if you just want to redo it. It functions in the same manner internally.

I thought it was a strange one, and you confirmed it. I will work to make it function tomorrow, otherwise, I will put a standard on.
