How do I refit the shaft assembly to my breadmaker pan?

I have the new assembly parts for my Breville breadmaker model BB290, and have removed the old parts, but have no instructions for the correct refit for the replacements. What goes where? I tried careful removal for inspection, but was unsuccessful. There are some very tiny pieces: shaft, white seal, a tiny 'C' shaped bit, and a few more.
Please somebody help! Our nearest service agent is over an hour's drive away!
