Small / Large mount info needed...

So...I hear you guys talking about different bar mount sizes, and would like to find out which I have for my 029 Stihl, and 359 Husky. I have a 18" on the 359 and 16" on the 029...been thinking the 359 could go to 20" easy and would give me a little more flexibility on larger logs. I can post s/n's if necessary (not sure if age makes a difference).

 

359 is k095/ small husqvarna

029 is 3003

 

Thanks...I can find charts, but none say anything about small/large, so I saw some bars in the classifieds and need to know if they will fit. Thanks again!

 

On husqvarna going from 18" to 20" your only gaining 4 drive links in 3/8" pitch. 68 to 72

 

Would you go to 24"?

 

I've never owned a 359 so I couldn't say. I'm sure it would be fine if it balances well.

 

Power wise it pulls the chit out of the 18"...I just hate to go back and forth on the big logs...or try to flip them to finish the cut.

 

My rule of thumb:

50cc, 16-18"
60cc, 20"
70cc, 24"
80cc -90 cc 24- 36"

 

Yea...the Husky is 59cc and 24" might be too much

 

Well the other thing is balance too. A 20" is just right on my Jred 2159 which is basically the same thing.

 

My rule of thumb is that you need 3 cc's of engine displacement for every inch of bar length.

 

029 Stihl has a large bar mount. 029 Super is really a 290 and larger/better than a plain 029. I ran a 20" 3/8 bar on my 290 no problem. I run 25 inch bars on my 361 saw all the time as well. But of course long bars are west coast thing...
