CLutch Hub Screw Size V4R?

Danger Close MFG · Nov 5, 2022

Hey does anyone know what size screw this is for the clutch hub or taken it apart? One of the balls in the hub came out of place and was locked to where it wouldn't rotate on the ramps. I took it off of the bike and shook it and now it will rotate (seems like the ball feel back into place) There is a total of 6 in there from what the parts listing says so I would like to see if there is any other issues in there. I tried a 3mm to little and a 4mm to big. Also in the parts diagram its number 16. Im thinking its a 3.5mm which I am missing of course and I wanted to check and see if anyone has taken this screw out and has the torque spec.

Its a 3mm screw my T-Handle is a bit worn tried another 3mm and it fits tight. Just not sure what to torque this screw back to.

Keep tightening it, until the force required to turn it, noticeably drops. Then, very gently, back it out 1/8 turn.

I'm (hopefully obviously) joking!

3mm it is. What do you think guys, Torque to 300Nm? That should keep it in place?
