Rad fan

One of the things I collected at the show was a replacement rad fan as one of the original ones was noisy and lumpy as if the bearing was mullered. Andy kindly replaced it and I went about fitting it.
I had noticed initially when I fitted them was that the fans are set as "pullers" not "Pushers".
Reversing the polarity wont be enough as the fans are shaped for max air flow in one direction
so it needs to be flipped.
The blades are held on the rotor as a push fit and retained with a circlip. One needed prying off.

It was then a case of flipping the blade round and refitting.
