How to disassemble an MS290

[bcorradi]

I don't know as I cut much more than that, and also fell and limp the trees........:biggrinbounce2: :hmm3grin2orange: :hmm3grin2orange:

The other reason you can't answer that is because you probably haven't ever run a 290.

Not a 290, but a 390, rated at 4,6hp here.........

...and they dicounted them heavily last year, but no, thank you.......
Over-heavy plastic saws, with bad anti-vibe and air filter system is not what I want.

Exactly how do you LIMP a tree???:biggrinbounce2:

Corrected.......

You guys are great! This thread was totally worth it even if I ended up shoveling my 290 into the dumpster. The wife and I got a good laugh out of all the banter last night.

The good news is the saw lives! After checking with the Stihl dealer regarding a ring compressor (they didn't stock one) I ended up fabricating my own based on the open port design of the saw. Basically, it consisted of 4 hardwood "fingers" that I strapped tightly to the piston using an automotive clamp. The fingers held the rings flush and were sized and positioned to slide into the open ports. I'm going to guess (though I don't know) that the Stihl ring compressor does something simliar. I was also a little concerned that tightening the automotive clamp (which I had to position fairly low on the piston) might snap a ring skirt, but all's well that ends well.

I think if I did a lot of these, I'd take Lakeside's advice and just buy the Stihl ring compressor. Thanks for the advice and the chuckles!

Good to hear you got your saw running and you got some laughs along the way.

No 290?? you don't know what you are missing.

I still want to know what a WIBE is

comparison shopping

OK, I always figured a 029 was the comparable to an 026, and a 390 and 361 compared.
Without AS, I would have never known I was wrong.:deadhorse:

I agree, if you need to buy a new cylinder and piston for one and pay someone labor you may as well buy a new saw. I've found the 290 family a very rare saw on this site. Reason I say that is because on here its hated with a passion mostly yet the folks I sell them to love them. I've sold many and rarely get a complaint and rarely have one cause alot of issues other than those that, like you memtioned, use pure gas instead of mix. Had one yesterday as a prime example of operator, not the saw, was the culprit. Check out the fuel mix.

My father bought a MS290 a few years ago and it developed a problem. He opened it up and found that one of the ports hadn't been deburred properly; he's a machinist. He took it to the dealer who promptly told him it was his fault; that he burned it up. The assclown didn't even want to discuss the matter. A burr was ingested into the engine and the piston and cylinder wall have deep scratches. He called the distributor who backed the dealer without ever seeing the saw. Now the dealer is out of business. I hope not all Stihl dealers are so arrogant and non-customer oriented. I have Stihl's ear on this now and will see where it goes. After giving up my father purchased another Stihl MS290. I admire his loyalty to a product. He had an 024AV for over 20 years and it finally failed. He also purchased a Husquvarna which he gave me. It runs well.

The biggest thing to remember on these saws, is to get all other parts out of the way before you try to get to the motor itself.
Reminds me of the 350 olds diesel. Nobody in the shop would touch them. You just kept removing things until you got down to the parts you needed to work on.
I can take one apart on about 10 to 15 minutes. If you need to work around something, remove it.

Now I AM slack jawed

You can tear down an Olds 350 diesel in 15 minutes?:jawdrop:

That would be grounds for a name change: Stihltech to Olds350aintsheettoteardowntech:jester:

oops

The 290, not the olds. Wish I could.:taped:
