Need a die for 200x crankshaft threads

[Frankencelery]

...at least I think it's the crankshaft. This '86 200x I'm trying to resurrect has really taken some abuse. I'm slowly getting together parts to reassemble the engine, just so I can find out if it will start. Somebody worked on it who shouldn't have been given tools. Among other things, the oil rotor was damaged, and I have a replacement, but the threads are damaged on the shaft. My guess is the aformentioned DIY'er apparently thrashed on the left-handed threads until they were stripped. I have the replacement nut on order from Honda but the shaft threads are damaged too. The Honda guy and I looked through the manual but couldn't determine what size the threads were. I need a die to clean up those threads, and I have no idea how to determine what size and pitch they are. Anyone have any ideas?

Thanks in advance!

The parts fiche might have the thread specs for the nut. If not, take the nut to the hardware and try to match it up, then order a rethreading die from that. Or, if youre careful with calipers, get the dimensions right from the nut and look them up in a thread chart. They'll be in metric.

McMaster-Carr is a good place to order tooling: www.mcmaster.com
or there is (or was) an industrial supply house in NE Des Moines just down off 80 that Ive bought bearings from that was good to deal with

don't know the pitch ,,,
This is the goofy left hand thread nut that holds the clutch in place correct ???

not just any hardware store will have left hand thread metric bolts, at least not around here. your gonna have to go to a place like MSC, or Wholesale Tool to get a die

No, I think the clutch nut was normal, this is the one on the on the oil rotor.

At the dealer, first we looked in the parts lookup, and there was nothing there, and he sent me to service, and we looked through the service manual. They have torque specs, how to punch the little divet to make the nut captive, etc., but no specs on the nut or shaft size.

It would have to be a helluva hardware store to have a 20mm (guessing) left hand thread bolt sitting around.

If you have a NAPA close by check with them. They have been able to get me tools when no one else could. Being as it's left hand thread finding a die might be hard.

If the threads are badly buggered up, it may take a lathe to fix it, might be hard to start a die on straight.

The part came in, and conveniently, on the packing slip it said, Nut, 16MM. Then I went to service and they had a thread gauge and we determined that it's 1.0MM. So now all I have to do is find a 16MM/1.0 Left hand die.....easy, right? Seriously, I haven't even started looking yet, so I have no idea how hard it might be.

you'll have to try tool stores like MSC.

Try this company. They have every thing. I get my reverse thread tapes ans dies from them.
