The puller I used to pull off my flywheel went to far down the shaft and stripped it out. Now I can't attach the flywheel back to the engine. I don't know what the part is where its stripped and I have no clue how to fix it if its even possible. I've attached a pic so you can see where I'm actually talking about. It's the part that leads directly down to the main spindle. It's either a 16.5 or 18.5 horse Briggs and Stratton from a Sears Craftsman LT2000.

:shocked:That is your crank shaft :thumbdown:NO fixin it replace it :mur:

As I posted in your other thread "OUCH". In the past I have repaired a crank by getting a carbide drill bit and drilling to accept a threadsert. ("NOT" a helicoil)

You have to replace the crankshaft. By your post I strongly suggest you seek a qualified reair shop.

I might as well throw the towel in. I'll just go buy one on craig's list and have a buddy weld it in the future. Thanks for the info!

Weld it? Why ruin "another" crank? Besides that, your crank and bolt are hardened steel and the flywheel is cast iron. The only way to correctly weld to cast iron, is to heat the entire flywheel to almost white hot, weld it and allow it to cool VERY slowly to avoid cracking. This would destroy the seal beneath the flywheel.

I bought another mower so I'm not pressed for time to fix this one now. I'm just not investing $$ into it. I'm looking for the easiest cheapest way to get it fixed and running.

I would get the next size tap(either metric fine or standard fine tread) that comes closest to the bore ID without having to drill it out and just tap new tread in it.
I don't think these crank stubs are hardened cause i machined one down last year in my lathe without difficulty.
If you can file it you can tap it

I'll give it a shot!! Thanks!
