K241 Governor shaft replacement

[Dashunde 6]

Hi All, I'm getting ready to dive into the inop governor on my (Grandpa's) 1965 1075's Kohler K241, the shaft will rotate all the way around, and I'm wondering how far I really need to disassemble it to get to the governor shaft?
Other than the governor issue it runs pretty good, always starts, makes good power (more than it should I think), and doesn't leak, blow any blue smoke or seem to burn much oil, so I'd really like to just inspect the cylinder wall, knock the carbon off the piston/valves/head, pull the cam and install the shaft... is that doable or do I have to pull the crank entirely out to swap the governor shaft and gear?

If you can turn that shaft all the way around, the flag is gone.  Sorry, but you need to do a complete tear down to fix that...if that is what is going on.  Pretty much, everything needs to come out to get to that shaft.  There is a point of tear down that let's you see what is going on, but to fix it, it is the first thing that happens to re-build a block.

Steve said it.

Seems to be an epidemic of broken governor shat flags lately.

Yep... when you read the manual the guv is the last thing to come out and the first to go back in. Just about to button one back up once and put the oil pan on ....  @Achto why did you leave that part in the parts cleaner?!?!

Pull head, pull shrouds, pull flywheel, lift engine off the pan onto a bench.  Remove the starter, bearing plate, rod bolts, push the piston out, push the crank out.  May be able to get at it...not sure on a 241 if you have to punch the cam out.

 

Look at the cam gear for any damage.  Youll have to check crank endplay and shim it back on assembly..inspect the bore, piston, look for cracks in the skirt.  Clean the pan out..find the flag part.

Yup, my very first thought. Second thought - inspect the rectangular flag and look for ANY evidence of chew marks or other indications it got caught up in the rotating parts on the way to the bottom. Any damage warrants a much closer inspection of all the rotating parts.

Also vital to look at the governor gear and flyweights, its the same level of teardown to access it except you definitely do have to knock out the cam

I think the broken flag pandemic is about a lot of members thinking their governor is not working right and when they go to adjust it, they don't realize you only turn the shaft until it stops and it doesn't take much (if any) pressure to hit the flag on the side of the block.  It's only spot welded and fragile.

Agreed Steve... some of the ones I have had out were just riveted or staked and loose on so I brazed them on. There can be some force on them you get her on the gov in tall grass or heavy snow and workin.

I had one break because my sleeve snagged the governor arm and tweaked it..they aren't the best made for such a critical hard to replace part
