Husqvarna 288xp 181 crankcase repairs

[Mattyo]

Special thanks to @srcarr52 and @Moparmyway for the repairs over the years. Thanks to @drf256 as well for help and advice and of course @Glock37 for the powder work.

That said...im doing some welding! They aren't super pretty ....but I'm trying to revive some of these crankcases back to functional.

One common issue on these is the rash on the pto side that wrecks the positioning bushing that helps hold the 288xp clutch cover in alignment. Not a crucial part but a pet peeve of mine to see these not fixed.



Also....on the 181s....there is no hole .... so ya gotta make one



So....weld it up!



Then grind it and drill it...



After a little more grinding and powder this will be more solid than stock.

Another one....

Other repairs...



This is totally doable which blows my mind. Ill get these things drilled and tapped and then powdered soon...

My hats off to ya, Matt. Good to see the effort you are putting into bringing these saws back to specs.

 

[Mattyo]

Nothing crazy...just stripped bolt holes mainly.

What process are you using to weld them

I have a tig... I think its set on 12a 100hz using 1/16" az92n blue demon rod.

Thanks
I don’t have a tig welder
But Shaun is only 45min away [emoji106]

Cool

I’d suggest cleaning a larger area around the weld. Mag n alum are super sensitive to contamination.

Look damn good there buddy. I find Mag very difficult to weld personally.

Do you mean 120 amps?

 

[Mattyo]

Nope...I mean 12 amps. I have a tiny tungsten with a 5 cup... clean on 50% iirc.

No point in putting a tip on the tungsten. It balls up immediately with this stuff. Its super porous... but once you get some kind of a puddle you can add the filler and start laying a bead.

Anything other than pure tungsten shouldn't ball up unless you are putting too much amperage through it.

I'll keep fiddling with it... tx.

Was really cool watching you repair those 288 cases the other day. Made them better than new.

Depending on the balance, but I prefer 2% lanth or CK LaYZr for holding shape on low balance high cleaning weld jobs.
