Restoring a '46 SD model A and want to replace the cork seal in the flywheel assembly and give it a good cleaning while I have it apart but I cannot get those bolts loose on the back side of the wheel. I do not have a flywheel wrench. Any suggestions? I have tried the knuckle joint on my 1/2" drive socket and also tried to use an impact tool. I'm stumped..!! Thanks

Clyde,
Original flywheel wrenches aren't cheap, but they are the only tool that will tighten and loosen the flywheel bolts effectively. I have them for sale if you would like one?

Clyde, the "regulation" wrench for these flywheel bolts is the best thing to use, but if you don't have one of these (like I don't) you can possibly do what I did. I heated a 3/4" drive socket extension and bent it in a modified "S" shape with about 3"-4" of offset. You can use your regular 3/4" sockets with this setup. Go to a hardward store and buy a cheap one that you can heat and bend and you will be fixed right up. Not a pretty fix, but effective. Mike

Clyde,
I read some of the responses, but don't think much of heating the flywheel bolts to loosen them. They are probably one of the most critical pieces on a John Deere tractor. Besides, I presume you will put the flywheel back on later and you'll need a good way to tighten the same bolts. I made a wrench that sort of simulates the old original ones but uses 3/4 drive sockets. I've used it on my A,B,&D, and I loaned it to our local dealer who used it on a G. If you want I can e-mail a sketch. You may be able to borrow an original wrench or even find one if you advertise. I would consider new bolts a real good investment when you put it back together. Lots of luck, Paul

Clyde just heat them up staying away from the mains with the torch as they will come loose

The best way to get them off w/out heat (which may hurt babbitt bearings) I to get 2 sockets & a piece of 1half inch thick x 1.5" wide x 3" long bar stock or whatever size you can find that is close & weld the sockets to the bar stock in such a way to give an offset effect when putting the soket on the nut & the half inch drive extension on the other socket. I had one made & it works nicely & it gives me more leverage when tightening the nuts. You sure don't want a loose flywheel.

I took a small torch and heated the nuts. They turned right off.
