3 shoe... got it off. (it's kind of like asking for a tracking number, as soon as you ask, it arrives)

Made a tool from a piece of pipe.

Hammered the snot out of the rest of it and it's now apart... Have a new pet named "Cranky"

Natural color.... nothing added. (except heat!)

Notice how the crank eccentric at the lower rod bearing has gotten so hot it is blue/almost black. That is from the heat generatred from that bearing going bad.

It should be a copper color from the factory heat treating process. They heat treat the entire crankshaft but do not heat trest the entire crankshaft that way since it would make the crank too brittle.
 
Yeah, I broke the piston skirt - stupid mistake but with the damage on the top I decided it needed to be replaced anyway...

I can believe the heat evaporated the oil! it got HOT in there!!

There was more oil when I took it apart - I wiped it off.
 
Is it a good idea to replace the crank shaft bearings - or should they still be fine?

Crankshaft, Piston assy, Bearings, Seals, etc may be close to what you can buy a new 372 for.

Yeah.... that's starting to worry me...:frown:

Why does your crankshaft look veeery dry? Maybe lack of oil is a reason for the seized bearing?

BTW: Husqvarna kick stihl's ass everyday. Usually, in sweden anyway, they say that you should replace your saw when the piston starts to wear. After that all the major costs come...

What is Sweden known for? Husqvarna sowing machines, Volvo cars, and Swedish bikini team.

I'll take West German engineering over Sweden any day.

They used to make some damn good dirt bikes (back in the day). IIRC, they sold the moto line to one of the Italian or Spanish firms and the quality went downhill. KTM (made in Austria), has taken over as the premier euro off road moto line as a result.

Or
They use poor quality mix oil. If you want the knock the lower bearing out of a hi-rpm/hi-load 2-cycle ngine, run Echo oil. If you want it to happen faster, use Champion oil.

Oh great . Just got done going through a six pack of Echo. I buy the small one gallon bottles.

Latest purchase was a six pack of Redmax. Any good or bad experience D'animal?
 
Short term there is not bad effects.

Long term use in the product is were I noticed it. I have been doing this for 30 years and I have seen a few things that lead to my opinion.

I have not heard anything about Redmax Oil.
 
Here is the 2 cycle oil I got. Going to run this oil on my Echo equipment and Stihl saw.

Is this the best 2 cycle oil for the Stihl saw?

Hey D'Animal - thanks for the quick help. Saw is completely apart awaiting parts. I've gone with aftermarket at this point due to price point. If they only last the rest of this season I am fine with that. After that I'll get a new saw.

Thought I'd point you to another forum, that I don't know if you are aware of. I found it when looking for my backhoe - but more recently found the forrestry equipment section. You might find some interest here (if'n ya havn't already been there!)

Forestry Equipment - Heavy Equipment Forums


Might find some interest in this one...

Germans don't know much about forestry - they are sadly enough big fans of "close to nature"-thinking.

Sweden have the leading forestry knowledge, together with finland. Sorry to say, but your way of forestry is a joke to us. CTL-methods are a big improvement if you would to introduce that. In sweden we already are talking about "lean production". Call me when you are thinking of that... ;)

I know what I'm talking about, since I have a master of science in forestry degree, educated side by side with students from all around the world.
