575XP Stripped Plug Threads

[FlyingDutchman]

Hey all, didn't want to derail this thread: https://www.arboristsite.com/community/threads/stripped-spark-plug-threads.171403/

Bought a Husqvarna 575XP that has a stripped out hole. The ham fists that had it before me used a solid insert but it was loose. We chased the threads, used another new insert, and some loctite. We found they had put the insert in crooked.

Because of the crooked shot, the gasket plug would not seat. So being a sneaky SOB, I got a tapered seat plug. It seemed to seal up really well, only a tiny tiny bubble of a compression leak. Ran the saw awhile, tightened up up, ran it again. Took it to the woods. ALL SEEMED TO BE MERRY.

Then it 'sploded. insert came loose.

I have a cylinder that is bad but the threads aren't damaged to set up the bore angle for another shot at the insert, but would need to buy all the tools/inserts etc.

So we are looking at one of the following:
An oversize insert for a 14mm plug done by a machine shop.
A standard insert for a larger sized plug (don't know how to find one that will work or how big I'd have to go.)
A nicer AM P&C Like a Meteor, run as-is.
A Huztl P&C with porting and massaging for fun.

There's guy's that will weld and rethread that cylinder.
Oem is always best.

Any idea what something like that costs? What sort of shop should I look to to get that done? Automotive machine shop?

This is worth a try as what have you got to lose. I have fixed a couple like this that turn out good. Another I tried to fix didn't...

A NORMAL kit won't work like in the video, . Threads have been repaired wrong with the same kind of kit and the cheap options are off the table.

I hope somebody comes along with something as I have a couple cylinders like that also.

A member here may be able to weld it for you. I won’t post his price, but he’s done two Stihls for me and they’ve been great.

Buy a new OEM jug and stop trying to put bandaids on your old one.

I’m here!
Yup, I can weld that up for you. $75 plus shipping.

You need to drill and tap it for a larger solid plug, plug it, weld it in, mill it flush, then drill and tap it for the spark plug. I installed compression releases in dirtbikes.

Pretty sure Shaun is gonna just weld the hole shut, drill, and re-tap to 14mm

Yup.

Coming back to this. Originally, resolved to get a new OEM cylinder, so contacted a seller here to get one.

They are already no longer available for this saw, and even the Meteor kits seem to be drying up. Pretty clear that I look into having it welded at this point, just need to get it apart!

Any p/c kits on eBay?

Try my dealer, “ chainsaws unlimited” in southbury, ct. he might have a p/c kit. Tell him I sent you.

I checked eBay when I created this thread and there was China AM, Meteor and OEM all readily available. Now just seems to be only if there is OEM it was nearly $400. But it looked sketchy. The problem is my budget is dang near dried up for even AM.

The gent that offered to weld it is a straight up guy. It will be better than new when he’s done with it.

Not far from me either so should be decent to ship. Thanks for the tip.
