Governor shaft movement?

[Pullstart 62,905]

Rylee’s K241 10 horse Kohler in Filly has about 3/4” or so of in and out slop in the governor shaft.  It this a tell tale sign the governor has exploded inside?  Luckily it runs fine for the time being, but if we need to open it up for some replacement governor work, well then Rylee will get a crash course on engine work!

 Sounds to me like somethings not really right inside if it moves that much. Problem is they're so hard to get to because the camshaft is in the way. You have to drive that long pan out to get camshaft out to even get to the governor gear .  I just got done doing one in one of these motors 

here. Rylee would be learning more about 

the heart beat of Filly. Do you have another motor to put on it while you are working on it? Keep us posted!!

I don’t have another runner to pop in, but she doesn’t necessarily need it to run before the weekend’s over to get to work on Monday

I think there is a sleeve on the shaft to stop the movement,  you will have to carefully remove the brass nut. I can get pictures when i get home

I have also saw where there is a real small clip ring on the shaft to limit movement so that is maybe what Tom is talking about. The groove is real small and the clip is just a wire and pretty dainty....easy to dislodge.  Don't remember if its in front or back of the nut.

 

Parts manual does show some kind of hooby doo ther … # T1... calling it a bushing.

Lordy, Tool Crib is right, its virtually a complete teardown to get to that dang thing!!

Yup that's the last part to come out and the first to go back in during a rebuild!

Fortunately  very few problems with tho but I have seen where the arm is staked on the shaft comes loose.

I climbed up to snap a few pics.  Sorry for the poor lighting...  Without the nut, there is a ton of slop... but the shaft won’t pull out.

No.... shaft has to come out from the inside. You do want the arm to ride in the center of the fly gear tho. That's what the spacer does. Maybe older K's had the dainty clip???

You have to loosen the pinch bolt and slide the throttle arm off to get at the spacer/clip. Then will have to reset it but no big deal procedure is in the manual.

 

That second pic has got way too much arm hanging out.

That's what's missing,  pull the brass nut and put one on.

Does anyone have one on a shelf by chance to measure the length for me by chance?  That would be awesome to be able to perform an external fix!

If you have a small groove you have to have a clip on it, if no groove then the bushing/sleeve.

So basically if I have 13/16” slop, make a bushing that long and give it a whirl?

I know this is an old post but I have a similar problem - assembled the motor and put the bushing/sleeve on the wrong side of the flag 🤦🏼‍♂️.

 

how did this work out? I’m thinking of adding another sleeve to the front end, from the outside after removing the brass nut. I found one on McMaster-Carr that’s 3/4” long and I’m thinking that’s “close enough”.

It doesn’t look like the parts diagram has any interference.  I’d say you are on the right track.  @WHX?? and @Shynon have more experience inside these than I do.  With that said, I can’t imagine any interference would be in play there.

I would think if the bushing/spacer is on the back side of the shaft the flag would not rest on the center of the flyweights or the shaft would not set in the boss in the block. 

If it does another spacer might just work. 

[Pullstart 62,905]

You should be able to tell if it sits in the block fully.  The exterior stack up with the nut and throttle arm should yield about 1/4” or less shaft stick out.

When I originally put it in I checked that the flag lined up with the governor pin, so that’s not a concern, and it does go fully into the boss in the block.
