flywheel nut...something special?

[Catfeesh]

Hello there,
I've got a Stihl 039 that I'm fixing up. Is the original nut that holds the flywheel on something special, or can I pick a generic one up at the hardware store?

Might be a dumb question, but I'm tired of doing things the wrong way.

It is metric, with a flange.
M8x1

Use the proper OEM nut!

 

[fearofpavement]

Did you lose the nut? If you need one, let me know, I may have a spare.

Remember, cross thread is cheaper than loctite.

This is solid, solid advise.

I found an ANSI grade 8.8 (or something high like that) flanged nut that matched the IPL spec (M8x1 sounds right) at my local Ace Hardware. It went on an 041AV that has been running ever since.

That said, if I had to do it again, I'd try a lot harder to find the OEM nut for peace of mind.

I have the nut, but I damaged the threads when I took a hammer to it trying to get the flywheel off, I also damaged the crankshaft threads in the process. I was trying to get at the cylinder because I damaged it trying to tap new threads for a HeliCoil spark plug insert.
I've since ordered an NWP cylinder kit from Baileys, but do need a nut. I can get an OEM nut, I'm just afraid of what the local dealer charges.

It's less than a buck.

 

[Catfeesh]

then add on their ~$7 service fee

Find a new dealer.

Wow! We ought to send you over to the middle east to handle ISIS!!!

What's a "service fee"? They add that on when you buy a part from them?
I would think most dealers would stock the nuts as they fit all kinds of models.

Haha, yep. The pros make it look and sound so easy. A rank amateur like me can get into a lot of trouble getting info off of sites like this one. Gotta learn somehow.

I'll get the OEM nut. I was charged the service fee for a starter pawl...maybe it was a fluke.

Thanks for the advice everyone.

 

[HarleyT]

If they charge too much, let me know, I'll mail you one. You pay postage.....

And did you mushroom the end of the crank snout too?

I damaged the crank threads a little, but otherwise it's good.

OP, I'm not being mean to you, it's just reading the above statement reminded me of this
