replacing clutch side crank case - 357XP

[Stubby]

Do you repair saws then?

 

Its been rumored !

[Huskyswinger]

Do you know if the little black rubber stop thats snapped off is supposed to be touching the bottom of its hole or if there is supposed to be a space?

 

Gonna get it tigged this week and need to know where its supposed to sit?

[wisecobandit]

Usually a bit of a gap and they don't touch. Its a buffer not a mounting.

That will tig or even ally wire thru a mig at worse.

How is this damage not purely cosmetic?

 

It's not like your two bar studs are affected. Once the cover's on who would even know it'd been damaged?

 

Why not clean the affected surfaces and slather on a nice thick layer of Marine Tex epoxy which is oil resistant and commonly used to repair gas tanks?

Nah Jomoco, it needs a better/stronger repair than epoxy. Tig Welding is the answer me tinks.

[Huskyswinger]

Just hope it doesnt melt the crank bearing

 

Hopefully getting it back friday.

Turns out that getting it tig welded was problematic

 

Took it to a local fabricator and he tried everything but apparently no matter what he did he couldnt get a decent weld on it - probably due to the composition of the alloy it's made of he rekons

 

In any case I need to look at other options...

 

If anyone happens to have a 357 crankcase assembly knocking about?

 

I know that it would be easier to get a new saw, but I like the 357 and it would be a shame to throw this one away as its a good engine!

hi, there`s a couple of 357`s ,spares or repair, on ebay. plus a new set of cases with all the gubbins in, for a not bad price if you`ve got all the rest of the bits in good nick.

They are an alloy of magnesium - an alloy is just a mix of metals to give a metal of required characteristics!
