Hotpoint twintub?

Hi.
I've got a Hotpoint supermatic plus model 9404 twin tub. Recently my spinner stopped spinning so after checking the belts and motor which are all fine, I took off the drive on the spinner to clean the drive 'shoes'. This done I've stupidly forgot what goes where regarding the parts I have left. I have a small brass pin, a split washer, a normal washer and the 'weight' that goes on the spindle after the drive that holds the drive shoes, and the nut. Can you please tell me where this brass pin goes and the split washer too?
