This little guy stripped out. Anyone know the best fix. Right now I'm considering helacoil.

Up-size it, like from an 036
So just drill and tap? Will I have to open up the spacer as well or just order one for a 036?

I doubt it will fit. It should drill out though. Just go slow so it doesn't break loose.
Sounds good. IPL says the 036 is an M5 I have some nylon spacers that might work well. We have some low head allen head bolts at work I'll check out. I'll measure the hole and wrap the bit with black tape so I don't go to deep. Thanks again, good advice as usual.

I'm sorry, don't go slow with the drill, keep it spinning but apply light pressure so it doesn't dig in too much at a time and grab that brass insert. The mag will drill pretty easily.
I use these,I think they work better than the heli-coil

tap it to 1/4" put in a allen socket head screw because I can probably find one lying around here somewhere

I’ve used these before on husky 288 top cover screws. This style does consume a larger amount of side wall then a traditional heli coil. So if that is close to the edge of a casting it might just break it off.
That's true, I think for a m5 you have to use a m8 tap.
can't you go up to 6mm. a lot of times I just run a 6 mm tap through existing hole if it is wallowed out and it works perfect
I'm talking about the thread inserts. The thread inserts are good if you want to keep the original screw size.
Try tapping the hole to 6mm and use a T27 Stihl 6mm x 20mm 9022 341 1300 screw/bolt.
The head size is the same and you won't need a different tool to tighten it.

Rethreaded but grabbed the M6x 0.75 instead of 1.0 so I need to grab a new bolt. I also drilled out the spacer and had to thread the brass spacer on the starter because the walls of it where to thin to drill so we will have to see how that goes after I get the bolt. I did not have to open the hole up any more to tap it to M6.
Hope it works out. I don't know if it matters but I would hold that starter cover as tight as you can against the case so the bolt doesn't tighten up to the cover before you get it tight to the case.
Yea I'm second guessing it now. I think I'll try and drill it out and hope for the best.
you could take a file and knock the threads down. That way you don't risk the drill bit cracking it, It's happened to me.
Clean the threads thoroughly, dab some J B Weld into the hole lining the full depth of the hole, let it sit a day, drill it for the appropriate tap size for the original bolt, use original bolt. Cost: about zero, strength: sufficient for the application.
I took a 3/16 chain bit for the dremel and knocked the threads down. Now an m6 slides right through.
JB is strong enough and suitable for tapping threads. Its one of their package claims, that's what I'd do also you can use the same original fastener. Versatile product that JB.
