: I've been seeing a lot of discussion on fans, what I understand is not to use an original for a driver due to them coming apart. I like the looks of the two blade and wonder if the aluminum repo is a good alternative? Is there more than one manufacturer and if so which is the better? Do these need to be balanced before use? What are your experiences with this type of fan? I've seen the 4 blades and they're probably more efficient but to me they look out of place, maybe if they where black instead nylon colored.

Glen,
I have an aluminum two-blade repro fan that has been running for about 14,000 miles.I use it on a Model B head/water pump and it is quite close to the water outlet hose (less than quarter of an inch). As I recall, I bought it from Bratton's and did not do any balancing, although I think that it should be checked.Be sure that the fan fits tight on the shaft.I have seen some fans where the taper doesn't match the shaft taper very well. This will cause vibration and may lead to failure.
John
