Correct that it wasn't assembled. I was surprised to find the flange in
the shipment. It wasn't supposed to be there and if it was it should
have had another piece to go with it. It slightly different, and won't
work with the existing parts. I don't think it was a manufacturing
error, both flanges spin on the new transmission just like the old
transmission until you hit a band of thread mid way down the shaft. It
looks like there is a some rust in the problem threads.
I held a triangle file lightly in the valley of the threads and turned
the transmission letting the file follow the threads. A couple of
passes it spins on correctly.
