Husqvarna 371 Hot Saw

[StIhL MaGnUm]

Well here it is I was just wondering if anyone of the builders here did this saw..Just debating on whether or not to bid on it..

Hi Rob, I can`t say whether or not you should bid on this saw, but based on the fact that it is listed by lead_harvester I`m going to say that the work was done by our own Jacob J. Send him an email with your questions, he`ll tell you the truth. Russ

 

[StIhL MaGnUm]

Thanks for the tip Russ I appreciate it,I'll have to send him a email and find out whats up with this saw.

Later Rob.

Do you think that saw
would be reliable enough for a clearing of a few acres or is it too modified?
Mike.

 

[StIhL MaGnUm]

I think it would be fine,as a matter of fact I don't like to run stock saws now that I have run a modified saw,I just sent a email to Jacob J about this saw I will post what I find out..




Later Rob.

If that saw is all that it is suppose to be I dont see why anyone hasn't jumped on the buy it now option. With all the port work and parts that should be a really good buy. The only thing that scares me is all the stray parts he has used and what I mean buy that is if you are going to really work it and cut volume with it she will be played out pretty quick and you be looking for replacement parts from all over for it. Would probably make a good part time saw, firewood and such.........later Wade

I see the saw has a longer stroke, isn't the only way to do that to replace the crank?

 

[Dennis]

2077 piston and rings?? How so? 2077 is 52mm bore...371/372 is only 50 mm....same stroke length...36mm...2077 head on the saw as well? Head bolts wouldn't match the crankcase...hmm

It appears to be bought anyway...by "Clem"

NO. Stroke can be increased via off set crank pins, boreing a new crank pin hole or using a longer rod.

 

[mikey]

Bw is correct,howerever when you use a stroker crank a different piston configeration is required.Who makes stroker pistons for husky chainsaws?Most of the people I know do this with four strokes and several companys that offer special pistons(most are forged) for popular motorcycle and auto engines.I didn't know these were available for chainsaws.

 

[Kneejerk Bombas]

I may be showing my ignorance(again), but isn't stroke measured from tdc to bdc? How does a longer rod increase that?

 

[cliff-1972]

To use a longer rod you have to a higher piston pin center.This will give you more cylinder filling and better leverage ratio.Thus it will be more responsive and have better torque.We do this all the time on our race engines in our cars.

I just talked to the seller....Jason Jenks...a good guy that I have dealt with on several occasions..

It was a 268 piston, not 2077, which happens to be 2mm taller (crown height) than the regular piston, the new base gasket(2 mm), was put in to compensate for that...and the skirt length was the same so the skirts were also 2mm higher
dimensionally, compared to the wrist pin location.
...so effectively they are not really "stroking" it..just more crankcase volume...

the porting work was done by Hunt bros.

Sounds like the saw should be a runner...congrats to whomever bought it.

...so effectively they are not really "stroking" it..just more crankcase volume...

Bet its pretty torquey.

 

[Dennis]

i am willing to bet as well Ben...

Doesn't this increase the dwell time that the crank is in the powerstroke? This is a common conversion on smallblock chevys, using a 6.0 in. rod instead of the common 5.7 in. rod

I'm impressed that people play around with different brands ,different models,parts,etc to assembly chainsaw engines like that one.Makes you realize that if you go to a saw competition you might need more than a drilled out muffler and a sharp chain.

 

[cliff-1972]

Rich,that would be correct.
