GO62 Woodruff key, or clutch key.

[Chargeride]

It's the key that holds the clutch to the main spindle, not half circle, but a rectangular one.
It can also be called a shaft key.

Can't find it anywhere and I've lost it.

Any ideas?

yes thankyou, theres so many different types and Im sure you have to get it right, I guess you can buy them outside of bafang.

I could probably track one down from that pic
Thanks again.

It looks to measure .2×.2×.4 (inches) or 5x5x10 (mm)
