MOPED ARMY

More details-

I manged to get the flywheel nut off - mostly by just pulling it off, since it was just free spinning - and it looks like the entire length of contact where it was on the shaft is pretty well stripped.

When I try to put it back on, it just spins...I can't get anything tightened down no matter what I try.

When you put a socket on either side you basically tightened it until it sheared the treads off, the threads can only take a certain amount of torque. You may be able to re-tap the end of the crankshaft and use a nut with a smaller thread.

Were they reverse(left-hand)threads? If so,you stripped `em. don-ohio

You should read Fred's Guide in this section of wiki: http://www.mopedarmy.com/wiki/Category:For_Newbies .If I understand what you did, its the nut not the shaft? If that's it here's the nut:https://www.treatland.tv/puch-clutch-flywheel-nut-with-washer-p/puch-clutch-fly-nut.htm. Or you can find it at the hardware store 10mm x 1mm. Read the wiki section before you do anything else, it will help you.

Looks like same thread to me , anybody else know what it is? My point was I think the nut was striped not the shaft, minor inconvenience.

Except that the Peugeot clutch nut is not the Peugeot flywheel nut

That may be. I was just pointing out the wording you posted as they were not links.

Could carefully turn the material down and tap smaller threads onto the crank, but then it'll be even less resistant to over torque. I would bite the bullet and replace the crank if indeed the threads are gone. If your nut took the hit only, then you are supremely lucky.

Right hand tightens up clockwise, left counterclockwise, remember it like this. lefty loosey, righty tighty . Sometimes its marked on end of shaft,"L", sometimes not. I saw three guys try to loosen a 2 inch nut on a shaft on a gear cut machine marked L till it snapped like thunder. It was R.H. in the book. (edited)

I don't know anything about Pug's.. but wouldnt you need to use a piston stop so the crank doesnt keep spinning when you try to tighten the nut? Maybe that's what the double ratchet thing is you're talkin about? lol

Why not dillon? Remember we used an impact on that moby like 30 times in one night without messing it up

Get or make a band clamp for the clutch bell, a caliper style pin lock wrench for the flywheel, or a piston stop at least for future easy life
