Do you prefer a 7 or 8 pin sprocket, and why?

[wiersy111]

Which do you prefer a 7 or 8 pin rim sprocket? What are the pro's and con's. I have used 7 pin sprockets mainly, and the only reason is because that's what we always used. I just put an 8 pin 3/8" on the Hutzl 360 I just built and it cuts fast.

Depends.

7 pin for more torque.

I prefer 8t if the saw has the power for it. It cuts more wood per tank of gas. I'll stick with a 7t if it struggles to bury the bar.

9T

Depends.

You're a bit young for that, no?

I am always pretty conservative on bar length and using a big enough saw. Most of the time I opt for overkill on the saw. My smaller saws are Husky 51 and 55 Rancher I wouldn't even think of an 8 tooth on them. But my big saws Stihl 044 and 660 I can't see a problem with an 8. For milling with the 660 it would be a 7. I'm just curious what others use.

I tend to reserve the 8t for ported 70cc and stock 90cc and larger, but I mostly cut hard wood.

It depends on what pitch your running, .325, 3/8 & .404 have different chain speeds in 7pin. An 8pin .404 is bigger than a 9pin .325 for example. Best answer to this is take the huge plunge (scary & expensive I know) and make the big decision to spend $3-5 on an 8pin rim sprocket. Fit it to your saw and see for yourself. None of us know the density of the wood your cutting, what chain setup you have etc, etc, etc. Its something you just gotta work out yahself.

8 pin for bore cutting is too fast! Can actually outrun the nose in deep bores. Experience taught me that.

10, Mo is bedder! Honestly I wouldn't have an 8 pin on a 3/8 20" 60cc saw unless I was cutting 10" and down in hardwood. maybe try and tune the chain for the 7 pin.

I run an 8t on the 056 all the time. I mostly cut hardwood.

run a 8 pin on my 650 with the 25" or 28" bar & it doesn't seem to care lol 9 pin with 18" (avatar pic) bar just for grins.

The big Homelite in my avatar only came with an 8 tooth .404 .One of my 125 Macs runs an 8 and one a 7 .The Husqvana 2100 runs an 8 tooth .375 on a 32" bar but it's 99 cc too . The medium size Stihl's with easy change rims I just run whatever trips my trigger at the moment. WTH you can change one in about 5 minutes .

8 pin on my another chainsaw and a narrow kerf chain.

 

[drf256]

7 pin. More oiling for chain speed and generally faster cutting.

8 pin only if using a saw with way too little bar length for its size, like a 70+Cc saw with a 20” or less.

I finally got around to trying my MOFO 036 with an 8 pin and a 16" bar in softwood. I'm normally not an 8 pin fan at all, but I think this setup works very nicely. That saw has an impressive amount of torque.

Decided to try 8 on a ported 55cc on a whim…works pretty good.

Also wondering, with a 404 7 pin being about the same diameter as a 3/8” 8 pin, and 404 having more kerf/drag, how much 404 can a ported 3120/395 pull? 42”? 60”? I bought 3/8” for my 60” but 404 stay sharp would be better in the dirty dry hard eucalyptus

7T is all I use and want.
I am mostly bucking turkey oak and higher chain speed results in slower cutting.
But, I have been told that I have no clue regarding processing hard woods by a member here so take it for what it is - just my own preference!

I do run 8T and 9T for fun, but that is all I deem it useful for!

Stock saws, full chisel round filed chains.
3/8", rarely .325" & .404".
Turkey oak mostly knotty, oak, beech.
Rarely locust, hornbeam, ash.

8 pin for videos, 7 pin for work.
