thank for breaking it down like that good stuff

Cool info & details for the people. My 390xp wears an 8pin.

Thank you.

Ty sir

Great video just 1 question: if i go from a spur sprocket 6 tooth to a center drive sprocket 7 tooth, will I loose torque? I'm assuming that i will, My saw if its relevant is a Stihl 009L

I would say a little but probably not very noticeable. I notice the main differences in bigger wood, like 12/14"++, as far as the torque goes. But the added chain speed will well over take that in 12" and smaller wood.

I'm new to chainsaw carving and need to convert some of my saws from a 3/8" pitch to 1/4". I am using Echo saws with spur sprockets currently. I am finding rim sprockets that are 1/4" pitch to do that job. However, if I buy the 1/4" drum and rim, what do I need to know to order a 3/8" rim so I can use the saw back and forth? For example, if I buy an Archer 1/4" drum and rim, can I purchase any of their 3/8" For Husqvarna to put on it or am I going to have to purchase a specific echo rim? I would think that as long as you get the right drum, all rims would essentially be interchangeable as long as you're using the appropriate gauge? Thank You

I assume the 1/4 drum will be a small spline set up. So as long as you get a 1/4 and 3/8 small spline rim, it should be a simple swap game. Only other thing I would look at and make sure of, is that the 1/4 isnt some special spline or something, I wouldn't think so, but just something to check in to. 👍🏻just remember to swap the bars 😆 🤣

Thanks for the info. My question is: stepping up to a longer bar, and moving from a 7t to an 8t sprocket will increase chain speed and help the engine pull the longer chain? 🤔

The 7t sprocket will be better for a longer bar, 8t gives you more chain speed but will hurt your torque for pulling the longer bar. If you have a torquey saw, it'll probably help out. The 8 tooth will be fine you just won't be able to dog it in or push as hard, let the chain work and it'll be fine.

@@dubbssawshop Thanks for getting back! I see on Amazon they also offer a 6t sprocket for my saw. For running a bit longer bar would that help even more with the torque. My saw is old runs good. Has a 20" bar with 56cc's. I plan to do a muffler mod and tweak the carb plus going from 063 gauge to 050 and a skip tooth chain should be things to help the engine when I need to switch to a 24" bar, ...and perhaps the sprocket swap.

@@pipesmcgee9270 that sounds like a great plan, yes the 6t will give you more torque. I'll help out anytime I can.

​@pipesmcgee9270 my cs 600 ran a 28" bar with full skip chain ok for some big trunks i needed to buck once I put a 7 tooth on it. I normally run the 8 tooth and then I forgot to switch back to the 7 when I buried the regular 20" bar in some heavy wood and cooked the saw... so yeah 7 tooth is handy!

I like 7 pin myself!

I always swap back and fourth depending on what saw I may use and what I’m cutting. 7 pin is all around good no matter what tho 👍

I just converted a CS590 to rim. I think I will try an 8 tooth.

8 pin should def pick up the chain speed a bit. The 590 is a torquey saw anyhow so it shouldn't suffer to much.
