Going through my Aurelia water pumps and parts over the weekend I came to the conclusion that the 3 blade fans as fitted to the earlier cars are much better finished cosmetically than the 6 bladed fans as fitted to the later cars. I think there were also 4 bladed fans used around the period of 4th Series B20s. The blades of all the 6 blade fans I have are almost unfinished having had a very rough cleaning up whereas the fan blades on the 3 blade fans have all been quite highly polished. Any technical reason for this or just cost cutting I wonder?
I find I have a couple of surplus working rebuilt water pumps which are available with or without the fan blade assembly. I have both sizes of body available - i.e both sizes of main mounting bolt hole.
These pumps have the early steel seal fitted - i.e not the later carbon/spring/rubber type - and are in working order with good impeller shafts and bushes with little or no internal corrosion. They have the side manifold for the rubber hose fitted.
