alternator rotation

In general can I change an alternator's rotation just by changing the fan?

 If not please say why (so I can understand the problem)

Discussion:- I want to fit a second / reserve alternator, and can only fit a unit in the "opposite direction".

 I have available 8LHA and 110-444 24V 70+ amp units both of which are CW rotation.

(The next challenge would be to source the fan!)

May be a dumb question - but if one doesn't ask...

Mike,

 

You are correct, the only determining factor when it comes to alternator rotation is the fan.  We have a bi-directional fan for the 8LHA and its part number is 107-120 (Raw, No coating) or 107-115 (E-Coated).  As for the 110-444 a bi-directional fan does not exist.

 

Good day,

 

Daryl
