3120 change to 3/8-7

[U&A]

I know people do it . I just cant find a number for the 7pin clutch drum. I assume the 3/8-7 sprocket that is on my 385 is the same sprocket i need? I have the IPL parts list and it shows no 3/8-7 options.

I appreciate the help guys.

This saw is a toy. No milling. So i want 3/8 like my other saws. Im thinking 7 pin is a good idea... my 385XP likes it. Or is 3/8-8 a better choice? It goes out for port work and a MM in December.

And .404 is not to be found in my area. My dealer has GREAT prices on 3/8 chain.

3/8-8 is closer to .404 rim diameter. Same as 385 rim spline. I run 36" 3/8 -8

So are you suggesting that the 3/8-8 is a better setup for my saw than a 3/8-7...?

Yes I would recommend esp with lower rpms limit on stock 3120.

Is it a limited coil? It wont be all stock as said. Woods porting and MM

Yes. Depending on which year they have different limits. Don't know the exact info between green and black 3120 coils.

If that’s a rim drive you only need to change the rim, not the whole clutch hub.

Any standard size sprocket will fit.
