Primary groove

[pedros83]

Noticed today that i have a small groove worn in the primary sheave right at the bottom close to shaft. This normal wear an tear? 14000km on the sled. I hope i dont need to replace the sheaves.

Provided its smooth and not a sharp hump, or groove, I think you are ok. Mine has many waves throughout the faces of the sheaves and has way more km than yours.

If your belts are lasting and you do not recognize any drop in performance you are good to go as is.
