Something definitely in crank bearings. Hits a tight spot with everything off. And when it’s tight the piston and connecting rod move freely.

Sounds like your crank is okay then as well.

Yep. I’m currently splitting the case. Any suggestions

Do you have the case splitting tool? If not I recommend getting one, or make your own like it.

 

[Homemade]

No I don’t have the tool. I have a heat gun and a rubber mallet. I don’t plan on doing many case splitting that I could justify owning the tool.

Enough heat around the bearing pockets might do just fine.

Leather mallet & propane torch worked great for mine.

Still haven’t found the offending hunk of whatever. Or where it came from. Yes screws are in the butterfly’s of the carb.

..... hold that thought

That doesn’t look good.

Well that's a easy fix at least.

Yep. I already have a meteor piston on hand. I’ll have to clean up the top of the jug and everything gets a bubbly bath and back together.

Just a heads up, the last saw I did that had that much wear on the inside of the crankcase wouldn't hold the bearing. From the looks of it, your crank bearing was also down and let the crankshaft wear into the case. Don't be surprised when you get it back together and see the outer bearing race turning inside the case when you spin the crank.

My guess is the needles made that wear pattern when they dropped down, I think the crank and cases should be fine once rebuilt, usually you can feel end play when the bearing pocket is worn out.

 

[Homemade]

My guess too Dustin. The bearins actually feel smooth. And I had to beat the heck with heat and hammer to get them out of the case halves. But I’ll make sure they don’t slip.

Not very often the wrist pin is the offending bearing. That's very interesting

Case splitter is usually under $60. As quick and easy as it splits em and leaves the bearings in the pocket where they are much easier to remove, hard not to justify the small investment. The basic splitter that looks kinda like a C-clamp works on every saw I've torn down that did not have stuffers. If I recall I paid $60 (before Husky lowered their prices on special tools) for it from my local dealer. I've done 242, 262, 288, 359 and a 394 with it.

I use the same splitter, just be careful not to bend the threaded rod, don't be affrad to bump the T handle with a mallet once a fair amount of pressure is applied, ask me how I know.

 

[RIDE-RED 350r]

Honestly, I haven't come across one that was that stubborn so far. Just about the point the t-handle starts to turn hard, it pops and easy peasy. But you've done alot more overhauls than I have at this point too.

I think the most stubborn thing I've encountered thus far is 394 flywheels believe it or not..I've done three 394 overhauls and all three flywheels were very stubborn to get to pop!

 

[dustinwilt68]

394 is the one that bent mine, I did a rebuild for a local dealer, then ended up trading for the saw a few months later. I had a friend make me new threaded parts, I got spares now, and welded the t handle back on.

I'll put some tension on the splitter then give the case a few love taps with a mallet if it acts like it doesn't want to come apart. Usually that'll do the trick....

Ummm if that bearing went down, what are the chances that it didn't damage the connecting rod? Not trying to be a negative nancy here, just thinking things through!

It's pretty easy to inspect the rod and big end bearing. If it feels ok and the cage is undamaged there's no reason not to use it.

Oh I agree, just posting thoughts on what needs to be checked closely for him before putting it back together and having a problem show up.
