Bar for echo cs590

[HenryIra]

Please forgive my lack of knowledge in advance. am looking at upgrading to a cs590.

I have a 18" /.050 /.325 bar. 72 drive link chain.

Will this fit a 590? I've tried searching but was not sure.

Pitch is wrong. Bar mount pattern more than likely is too

590 stock has a 3/8 sprocket.

590/600/620 20” will be a 3/8”, 70 DL chain

Thanks for the replies. Can the sprocket be changed to,a different size?

In short yes but it’s not worth the money... you are better off buying a new bar and chain in 3/8 or you will have to buy a CS600 clutch drum, sprocket (if they make in that size in .325”), washer and retainer clip just to use the chain you have.

This is what you would need plus small parts;

Standard bar mount for a 590 is a D176, but with that it’s only 70 dl compared to a “standard” 72 dl for 20”. TsuMura makes a D176 Mount bar that is 72 dl, a high quality bar. @fordf150 carryies them.

Theres nothing wrong with the bar that comes with the saw. Why do you want to change it to 18" 325? A 590 will pull 20" 3/8 buried all day and not complain about it.
