Thread Repair Recommendation......

[Adirondackstihl]

Anyone wanna sell me one Timesert and let me borrow the install stuff?
Or maybe even the install stuff for M6 helicoil?

I’ve been slowly working on this saw for the last few months and was about to finish it up last night when I ran into this snag. Literally had the muffler to install and the inner spike.
Depressing as all hell.

I may say fuggit and attempt to JB an M5 helicoil there.
Or reverse engineer and JB a fuggin M5 stud in place and use a nut to fasten the spike.

If it is too big for M6 the m5 timesert will have to be epoxied in. I should have one if you want to try. Pm me your address if interested.

PL Premium is a construction adhesive, it is not an adhesive for an office environment. It worked for me, but you guys do what you want. If these tree company guys did not destroy them, they must work pretty darn well.

How long have they been in use ?

There is the other option.... smear the hole and m6 bolt with jb or that marine epoxy and install it. Its a commercial saw. How often does a real world user remove the dogs to polish them?
Cheap and probably effective.
Fwiw, you can't tap threads in jb and get a fine threaded screw to hold in this application

I’ll take you up on that!
Thank you sir!

About 6 months.

Have you ever used it?

I always tap to 6mm or if terrible install a timesert 6mm.

Find a fine thread bolt, metric or SAE that will fit in the hole with a clean up tap. Lop off a suitable length and drill/tap for 5mm.

Ten minute job in a lathe.

I'm not a fan of epoxy. But there's a few that work quite well. Jb is ok, Jb marine/water is better. Jb quick sucks. Marine tex is good. Lord products fusor structural is great (really like the heat set). Devcon structural is the best but I don't know where to get it anymore, or if they even make it anymore.

I would go with the M6 helicoil route. If down the road it fails then Mustangmikes route.
I have a M6 Helicoil kit I can send you to use if you think that would be the way to go.

I think there is enough meat for an M6 helicoil

Pm your addy if you would like to use it.

That looks like it would certainly work

I have ez lock solid inserts in 5 and 6 mm if you would like one sent. I know the 5mm need a 8mm hole to install. The 6mm would obviously take a larger hole. No special tools needed just a tap and red Loctite. Basically a readily available version of the idea suggested of making an insert on a lathe.

I just surprises me so much that a mighty Stihl would have a fastener problem...lol

Sorry had to throw it out there
