Hobbit / PA50 Flywheel nut stripped

hey, I used an impact to start my hobbit and stripped out the nut

what's the factory flywheel nut? Anyone know of the next size down? Possibly american coarse thread to die it down to? Yeah I'm kinda stupid

hopefully a die will cut through the crank

Re: Hobbit / PA50 Flywheel nut stripped

how do you not know this after all these years of hobbitting?

i'm pretty certain it's an m10x1

if you stripped the nut, just replace the nut. if you stripped the crank, 3/8" is a real common slightly smaller american size. fine thread is really close to 1mm.

Re: Hobbit / PA50 Flywheel nut stripped

:P I was @ going to be at the hardware store and wanted to buy some nuts / rushpost

I know, you'd think I would strip more!

I'll check the parts catalog to double check

Re: Hobbit / PA50 Flywheel nut stripped

If you need a Pa 2 crank let me know. I got one for shipping

Re: Hobbit / PA50 Flywheel nut stripped

Oh I forgot, your a bonehead. Ha Ha Ha Ha Ha

Re: Hobbit / PA50 Flywheel nut stripped

Can't fit die over the crank end, whoops

Re: Hobbit / PA50 Flywheel nut stripped

Do I just grind t 1/4" of the crank so I can die it? and it will take care of the rest? or should I just take it to a moped professional?.

i got 3 cranks bad... I swear, its not me.

I have new nuts, but by using taps & dies I could not - for the life of me - figure out the pitch, it was really frustrating. You would think with the [new] nut in hand and a tap you could figure it out but no- it snags...

Re: Hobbit / PA50 Flywheel nut stripped

are you using a chase tap or a cutting tap.

Re: Hobbit / PA50 Flywheel nut stripped

Are you using metric tools?

Re: Hobbit / PA50 Flywheel nut stripped

I'm trying to go to standard, because the sizing goes down so much from m10 to m8, I thought 3/8 looked a little bigger, maybe I went too small, I was thinking it was m8 and I was going down to 3/8

ugh, I'll find some one who knows what they are doing.

I think the tap set was a cutting dies, not finish dies

Re: Hobbit / PA50 Flywheel nut stripped

what the hell are you even trying to do? you stripped the nut... buy another nut... what's the big deal? why are you trying to run a die over the damn crank??? jeez... pretty sure I have found m10x1.0 metric nuts at the hardware store before... if you want I will go buy one and mail it to you???

Just go to a bar at 1am and spit in everyones drink cuze you need a beat-down.

Re: Hobbit / PA50 Flywheel nut stripped

pretty much at this point , you need Mopeds Anonymous Beatdown fer fuckin' that up.

Re: Hobbit / PA50 Flywheel nut stripped

Good offer Ryan, I can source a nut though :)

I was trying to figure out which m8 and 3/8 nut was which pitch by testing with the tap set but It wouldn't thread in all the way for any of them.

So either its a 'Cutting' tap, or 'finishing' tap and they aren't made to thread into the correct nut because of their purpose, or I had the wrong sizes.

I haven't butchered anything yet, there is still time to though.

The third bad hobbit crank came that way!

I have just now, learned to... Keep the air tools away from cranks!

Re: Hobbit / PA50 Flywheel nut stripped

for the most part I would never run a die over a crank... they are hardened and as such will be very difficult to make new threads on.

Re: Hobbit / PA50 Flywheel nut stripped

I had a shop do it for me on another crank - It was left hand thread and they ran a die over it, right hand thread. That is what I meant by 'bringing it to the moped shop' they saved my butt last time.

Re: Hobbit / PA50 Flywheel nut stripped

From what I have read - and in this case - the threads aren't hardened, maybe the crank webs are?

Problem fixed with a die. New m10x1.00 nut

Re: Hobbit / PA50 Flywheel nut stripped

HOORAY!!!!

Yeah, no more impacts.

Re: Hobbit / PA50 Flywheel nut stripped

all this over a 'chase die'.

I know this sounds funning but if you need the fix the theads on the crank the easey way is to do it is, take a pipe cuter and put it on the good treads behind the bad spot and carefully tighten to cuter on the good threads but dont force it then turn it backwords into the bad threads and work it back and forth till you get the messed up ones and clean as you. this realy does work. good luck

Re: Hobbit / PA50 Flywheel nut stripped

great side of the road trick, man...

Re: Hobbit / PA50 Flywheel nut stripped

I had a bike come to me, stripped threads on the crank, I avoided working on it and then thought about 1 day. Put another washer on before the nut, problem solved

This is an old thread but it shows up at the top of Google search results so I am updating it to possibly save other people that come across it in the future from wasting their time-

These posts are WRONG. The flywheel/clutch nut is NOT M10x1.0, it is M10x1.25

I want my two weeks back lol. M10x1.0 is a rare special order size. M10x1.25 is available at every home depot.

Ah well

Re: Hobbit / PA50 Flywheel nut stripped

old 7 year post revenge is sweet... If i took u two weeks to figure out the differance between coarse and fine then...
