    Posted: 29 May 2023 at 8:23pm
Drove my new to me 1965 190XT gas to a tractor show on Saturday, have oil leaking from the governor shaft.  The arm and shaft rotate freelay but the shaft has 1/8" of end play and moves up and down in the bore in the governor housing.  Is there a way to fix the oil leak without taking the governor apart?  Looks like the only way to get access is to take off all the sheet metal and remove the radiator.  Any advice would be apreciated.

So if I go through the whole removal of the radiator can I even get parts for this governor?  Anyone have a good source for those specific parts?

I have removed the governor weights/shaft/gear assembly without pulling the radiator. I have also replaced the leaking oil seal by driving out the roll pin and removing the arm to access the oil seal. You say there is up/down movement of the shaft and arm ?? Not sure what can be done in chassis with that. I think once the governor weights are removed the fork can be unbolted from the shaft inside and then pulled out the side. Easier to do with hood and radiator removed for sure, but I have done it without.

Driving the tractor a little more there is a lag in response when I open the throttle and it seems like the governor is not very responsive when the tractor encounters a hill or additional load.  Pulled the sheet metal and radiator.  Got the cover off the governor and here's what I see.  How do I proceed? 


Here's the parts diagram I got from the local dealer:



What should I be checking that might be giving me the problems I have with throttle and governor response?

Generally, not tearing it all apart until you have properly adjusted the linkage  to the carburetor!!     I thought you were concerned about an oil leak and looseness in the shaft ??   The governor weight assembly will pull right out of that hole if you disconnect the link rod to the carb and let the governor arm fall way down to horizontal.

I am concerned about the oil leak as well.

There was a bend in the rod from the carb to the governor arm that was causing a little interference, fixed that and the problem of response didn't change.

What are the wear points of the governor that might also be causing the issue and how do I check them?

Proper adjustment of the governor to "synch" it to the carburetor. Hand throttle wide open with the engine OFF. Disconnect the link rod to the carb at the front. The length of the rod should be just so you can slide the pin back into the yoke when the rod is pushed to the rear as far as it will go. From that point I would turn the yoke 1 more full turn shorter and maybe even 2 full turns shorter. A drop of oil on each end of the link rod. No binding anywhere. Even oil the spring to help it slide. That is proper adjustment. Now, I will tell you a stock OEM governor on those engines wasn't very impressive until you got up to 2,000 RPM or more. They just weren't. I have worked a couple of them over to help with mid-range sensitivity but it takes governor weights from a Gleaner model G combine to do that.

Will go through that procedure and see if that improves the response.  Guess I may have been a little hasty with the teardown but really do want to fix the oil leak.

Thanks for sharing your experience, I do appreciate it!

Replaced the governor arm pivot shaft, bearing and seal.  Back together, did the linkage admustment to synch the carb to the governor.  Runs better with somewhat better governor response than before, still not snappy like my WD45 and D17.  Like Dr Allis said these weren't real snappy governors.  And no oil leak!
