How much damage?

Well, I'm kinda of at a lost and never had this happened. My 046 I think shelled its bearings and shredded the clutch assembly. Did I miss anything or misname anything. I've got a email in into Randy, since its going in for its port and MM next week. I'm hoping it hasn't done any massive damage. Any advise?

I was sawing away cutting a 18" crotch off a main log to clean it up. I had tightened up the chain, it had loosened up. It was cutting and then all of sudden it started smoking and by the time I got off the trigger and out of the wood. It abruptly stopped, almost threw the saw out of my hand with the motor going upwards. It basically locked up. When I took the cover off everything was pretty much into pieces.

 

Brake was set?

Is the piston scorched? Or is just the brake band and plastic welded together?

 

Can you move the crankshaft in its bearing at all? Other than rotation that is?

EDIT: Looking at this a little closer, it looks like the one clutch shoe may have failed setting off the rest of the carnage. A clutch, drum, and needle bearing and you should be back in business.

 

No it was just humming away and then it started to smoke. As far as I can tell, I'm no way a trained eye, I think the piston is fine. I think its just the outer parts. I can rotate the little thingy with three fingers.

 

I'll clean it up in the morning for a better look, a lot of black stuff in there. But I can move the little thingy with the three finger, which I assume moves/drives the piston. Ok thanks...

 

It's not so much the saws' fault as it is the clutch itself. It's hard to get a clutch shoe to just separate like that. I don't know if the springs broke (most likely), clips failed or if the shoe itself had a defect. I have had saws in here that had clutch failures, but they showed signs of severely overheating the clutch and I don't see that in any of these photos. And those saws certainly had more time on them than this one.

I assume this saw was in original condition or was it rebuilt?

 

Me too, but mechanical failures happen. I just want to make sure that I get it fixed, cause there more wood to be cut and its heading out for its port job this week. I just wanted to get a ideal what needed to be looked at and what parts needed to be replaced.

 

Yea, it was original, it was the one that I bought from him off the site about month ago or so...

 

I had a saw that had the break set and blew up a clutch. I didn't do it.

But I bought it that way.

Randy would go through it for a few extra bucks..

 

Kinda of what I hope. I sent him a email tonight. Figured I'd call him Monday and talk to him about it. But I remember you had a issue with one of your saws, right off the bat. I was going to back track to try to reread it if I couldn't make progress on this tonight. Thanks.

 

Dont feel bad, appreciate the concern though. That shows your character, for not only the sale of the saw, but also after the sale. You are a stand up guy. ... I've ran several tanks of gas through it and never felt a issue, so there wasn't any fair warning. It was just a sudden thing, which leans me to mechanical failure like the others have said.

 

I'm wondering as well.......

 

I'd be curious to see the front side of he clutch drum too. I wonder if he found any of the needle bearing?

 

???? I dont know. I can get better pics in the morning. And I'll look closer in the morning, just didn't feel like it tonight. I wanted to get a clear mind...
