Default John Deere Governor Help

I'm a newbie working on my first engine, a John Deere 1 1/2hp model E. It started making a rattling sound when I crank the fly wheels by hand. I investigated and the governor might be the issue. It seems like it is loose in the bearing, not back and forth like the nut is loose, but like the bearing has worn. The rod that goes through the bearing seems loose as well. I don't remember it being this way when I put the engine together about 1 month ago. I've run it about 20 hours. How much "play" should there be in the governor, and how can I tell if it has worn for some reason? Is there a spec for clearance between the governor shaft and the bearing? Any help is appreciated.

My dad's 1-1/2 made the same noise. Found worn bushings in the gov. and cam shafts. Put in new ones from Hit&Miss.

I took the governor out this morning, and the shaft is a bit rough. The bushing is rough on the inside too. Do I need to do anything with the shaft to clean it up or would a new bushing do it? Any tips on installing the new bushing?

Are you able to post pics of what you have??? Someone may be able to help you with a fix?? I have a few of the worn out jd engines but seam to run fine even with a sloppy loose cam or govenor? Maybe your engine is more severly worn than mine?? I have a govenor in the parts bin that was very noisy, I swapped the govenor weights out with another jd gov. and the noise went away??? Just my 2 cents worth. I am only a lttle over an hour from you maybe we can get together sometime and figure this thing out? marty.

From my experience the noise is most likely being caused by a worn cam shaft bushing.
We have been through well over 200 JD engines through the years.
If you want to give me a call the # is 636-285-2519

Here are a couple of photos. As you can see, the shaft of the governor is a bit rough instead of smooth. The inside of the bushing is about the same. Will this machine continue to run this way or will I need a new bushing and governor? I plan to make ice cream with it, so it will see some use.

Sorry, the photos didn't upload on the last post because they were too large. I think they will attach this time.

Those look better than mine!! But you may want to have a mach. shop measure the cam, and gov. Then measure the bushings to see how much slop is in the 2??? You look ok, but looks can be deceiving.

I fabbed a puller to extract the bushing(s). Find a socked that's a tad smaller than the outside of the bushing. Place it inside the block against the bushing. Get a long bolt, put it through the socket. I think I used a 1/2" carriage bolt that way the square shoulder should fit right in a 1/2" drive socket. On the outside of the engine find a socket larger than the bushing. Place it over the bushing. The bolt should be long enough to go through both sockets. Place a washer and nut on the bolt and carefully tighten. Make sure the socket inside is pulling only on the bushing. It should come right out. The bushings I got from Hit&Miss were slightly undersized. You can ream them for a proper fit. Hopefully this long winded explanation makes sense.

That fab'd puller sounds like a great idea. Once I get this pulled, can you press the new one in with a large "C" clamp or is there a better method.

I have two more ice cream events this year. I think I will put it back together and run it, the put in a new bushing in the fall or winter...

Yes a C-clamp would probably work. You should be able to just tap them in with a driver or a socket.

Jim White is one of the good J D men!! While you got that gov tore apart make sure you check the cotter pins that hold the weights on. Dad gave my brother and I both a set of Deeres everyone I checked the cotters where wore bad one almost in half. Replace with HIGH QUALITY STEEL ONES that they use for wheel bearings on trucks not the cheap soft ones that come in assortment box...
