broken out thread in Husky 262 engine case

[openspaceman]

Any ideas on how to repair two of the screw threads which hold the plastic cylinder cover/air filter housing to the body. I broke them out a very long time ago, have tried araldite to hold a threaded piece in without much success.

 

I have an acquaintance who is an ace TIG welder but I think it is mag alloy and doubt it's weldable.

Helicoil can work, there are cheap kits available on the bay.

 

I have used M6 successfully.

I found the helicoil method easy and quick, if you don't feel confident to try pop in to your local engineering shop, they should be able to help.

Thanks, I've used helicoils quite a bit, from spark plugs in cars to exhaust studs in saws but this time the whole side of the threaded section has broken out on one side.

Nice big blob of a quick setting chemical metal. Then when it's set file it down to shape, drill it and tap it.

 

Not ideal but should do to hold a cover in place.

fill them up with chemical metal/ jb weld and retap threads? Just don't overtighten the screws tho afterwards.

 

If you've broken out the sides use tape or similar so it doesn't run out everywhere before filling the holes

You may be able to get clever and fabricate a retaining plate for the broken part or even get an insert in there and JB weld it in place - just repaired a real busted up 372XP rear AV mount so much can be done - just need to get creative:thumbup:

 

Get an image up so we can kick the solutions around it!

I'm going to go with the others. JB weld is magic stuff

Here are two

 

 

 

I have a complete saw with seized piston but fixing these must be easier than a complete engine swap.

 

Delayed by the feel of warm winter sun on my face, listening to bugle and remembering an uncle I never met.

Looks like the top one needs building up with a new piece of plate and the lower one building up with epoxy - you can pin steel in to the casing as long as you don't drill in to the tank.

Just make sure everything is grease/oil free and dry before you try rebuilding up the areas. Also make sure the area your applying to is nice and rough to get a good bond.

You may find you may even be able to just jb weld a nut in place and build it up on the sides if the threaded area doesn't need to be to deep.
