radiator coolling fan specs to get generic ?

Post by stevodemo on Sat 25 Jun 2016, 5:02 pm

Hi,
My CB500 1994 radiator cooling fan is gone(well the motor ,I can spin the blades) and as its very rusty I'm thinking of getting a generic type (non model specific) fan to replace. I could take it off and see if its fixable but just don't; have time for that.I tried to wire it direct and nada so it really is gone!
I'm not technically minded so wondered if anyone nows the specs of the OE one so i don't get oe that won't work.
Also does the OE one blow air outwards or draw it on?
Thanks ,

Stevo

I'd have thought it'd pull the air through the fad so it's not fighting airflow whilst on the move.

Any 12v DC fan should work (even a pc one) so long as it's dimensions are the right size to fit the rad.

Sadly fans have a habit of doing that.

Anyway, yes, almost any 12V fan of a similar diameter will be better than nothing and yes, it wants to be mounted such that it sucks air through the radiator from front to back, that is, the same way as the air goes through when you are moving.

It might be worth posting in the 'wanted' section - it is possible someone else has a fan to hand.

The problem with using a random PC fan (or whatever) is the mounting - it shouldn't be a problem, but a little bodging/adjustment may be required to achieve the desired effect...

As far as second hand ones are considered, there is one on ebay....
