ms200 crack in crankcase

[Blairito]

I recently bought a used ms200 rear handle saw, whenever I buy a saw I strip it down and check everything after a good cleaning.
i noticed a crack in the case right where the bolt goes just to the left of the chain tensioner opposite of the bar stud.
at this point I'm wondering if i should buy the hustle crankcase, or try to repair it

Clam shell engine?

pro saw, magnesium, but I'm pretty sure I wouldn't need a puller to split the cases, considering the bearing design.

See if you can find out who bought this lot and see if they would be willing to sell you a case half.

Putting two missmatched case halves together is not recommended.

I'm thinking the aftermarket case replacement route, does anyone think this may be the wrong direction, aside from possible casting flaws of the aftermarket case, are the bearings and seals included up to par?
can someone send me the service manual for this saw, I'm sure i could get it back together fine, upon disassembly i didn't really pay much attention, i like the challenge , just don't like putting everything together and realizing i didn't route the coil wire or something through the crankcase.

Have it welded.

No.

It's not recommended to break the saw either but stuff happens.

Yep, it’s worth it.

Were you referring to mismatching an OEM case half with an AM case half? Or any case halves that did not originally come together?

Yes.
