1944 johj deere A flywheel removal

Tstoner · Jan 2, 2023

I have a 1944 A (hand start)..I'm in the process of a total restoration and will start removing the crankshaft this weekend. Was wondering if anyone could give me any advice on removing the flywheel?

Removing the flywheel is pretty much straight forward----once you get the proper flywheel wrench to loosen the bolts. There is a wrench made for this purpose. Some people arrange a socket with a bent extension to fit. The flywheel is HEAVY. Put something under it to catch it. Having the proper flywheel wrench is most important when re-installing the flywheel. The bolts must be TIGHT. Be sure to leave .005 to .010 clearance in the flywheel side to side movement.

Thanks for the reply. I guess I was leaning more towards the process of physically getting it off. Do guys find themselves having to use a puller or are they fairly easy to get off once the bolts are out? I have never taken one off before

I did one a long time ago and just pulled it off by hand. Would not do that 50 years later, I'll use a hoist. Wasn't difficult, it slid right off
but the splines were in excellent shape. If it's been run loose in the past it will require some wiggling. Be careful of the drive pin on the
inside. Don't break it.

Going back together, get crankshaft end-play, tighten two flywheel wheel bolts then torque bolts when all is set..

Find and verify the timing/match marks on crankshaft and flywheel BEFORE removal, then be SURE to match them up again when replacing it on the crankshaft.

Sometimes they can be hard to get off of the crankshaft. Make sure exposed splines are clean. I have had to drive wooden wedges into the relief cuts to help loosen them at times and at other times I've had to fab a puller utilizing the two holes at the outside of the relief cuts. Sometimes a hammer and block of wood against the back side, rotating the flywheel to make sure force is applied evenly, is all that needed and sometimes simple hand pressure will do it. Make sure there are alignment marks for reassembly, if not, make your own. Also on assembly, make sure the pin on the back side of the flywheel hub aligns with the corresponding slot in the slinger housing.
