I will take a guess and say straight gas,no mix?

Ouch, that was my thought too.

 

[computeruser]

Geez, did he try to run it on chunks of a grinder wheel instead of gas?

Air filter was clean but you are onto something....

Yes it was straight gas...
But their is a lot of build up in the ccase

Scott

 

[cuttinscott]

This was actually about 2 1/2 tanks of straight gas.... thats why there is sooo much aluminum in the crankcase..

New Piston and Cylinder, Crank & Bearings, Gaskets and Seals, And of course a new batch of Dolmar 50-1 premix and she will be as good as new.

wow,that is the most pulverized saw I have ever seen,it lasted 2 1/2 tanks on straight gas,an impressive stress test!!

Scott,
How does the total for all the parts and labor to fix it compare to the cost of a new one?

 

[cuttinscott]

parts approx $415. and a hour labor

New saw $899.00

Not bad. Stupid is usually far more expensive.

How did everyone guess straight gas without seeing the intake side of the cylinder or the intake side of the piston?

Straight gas was a good guess, but without seeing the intake side of the piston or cylinder, a lean carb could have caused that, as well as bad seals, bad base gasket, etc.


Lots of aluminum in the bottom end, though. Haven't seen one eaten up that bad.


Scott, did it blue the rod at all? hard to tell with the aluminized protector covering it...lol
Was the Crank seized?



EDIT: I see the intake side of the piston in the pic with the exh side of the cylinder.

 

[rahtreelimbs]

How bad are the crank bearings???

 

[sawinredneck]

I am astounded that the saw ran that long on straight gas!!!! That is a well built saw I must say!!!! More props to Dolmar!

You mean, props to Solo. Dolmar buys that saw, they don't make it.

I Think You Have That Backwards Sedanman.... Ever see a Sachs-Dolmar 134 which evolved to the Dolmar 9000 and now the 9010

1 hour labor? you give your time away far too readily... You already have 10-15 minutes plus/minus in it!


I just did a similar thing on a clean MS660 - It was close to 2 hours... and then I messed with it for another 30 minutes etc.. (pressure test, check the carb, test running.. etc..) just to be sure..

 

[sedanman]

I could be wrong, I have never had a 9010 apart to see if there were any logo stamps on the parts. I do know that Dolmar buys powerheads for the string trimmers, I didn't think it would be a stretch to buy a saw.

no this saw did not sieze, the crankcase and crank are loaded with aluminum from the piston I will not chance the main bearings or the crank for reuse. It will get a new crank, bearings piston & cylinder and will be like new this is a low hour saw and is worth the rebuild.
