Default Another way..

We have changed our Ford Generators to 12V by swapping the Ford body and field coils for a Lucas one. The Ford Armature and end plates fit straight in/on without adjustment.

I will have to look at it on Sunday to tell you what Lucas model we used.

Default 12V gen

Hi Rob, we use the Lucas C45 12V fields, that is all you have to change out of the original gen housing, but of course you have to change the regulator and put any resistors in line for the oil and temp gauge because they still stay at 6V.

There is a company called "Powergen" that makes a 12volt alternator that looks identical to the original generator. It also includes the mounts for the Ford V8 and is a straight swap fit. It comes with a single belt pulley but it is easy to swap over a dual belt pulley. I have one for my carrier engine and it is an easy job to change from the generator to alternator.

How did you get around the fan extension issue ?

Richard, Matt is talking about an Australian carrier which uses Ford commercial parts, has no fan extention, and is a single belt at the generator.
If your armature is o.k. then you have options. Otherwise, you might be able to adapt the generator drive dog.

Just weighing it all up Lynn. I know mine needs a set of brushes and the armature is a bit ropey... What are the benefits of running an alternator over a generator other than it charges the battery on idle ?

All this elastic trickery is lost on me

Get the armature checked out, If it checks out o.k., you can get the commutator turned.
Then you need to under cut the mica (make a tool from a ground hacksaw blade)
The problem with the generator is that it has a bush at the rear. An over tight belt will quickly stuff the bush. Then the armature "poles" (hits the pole shoes) and burns out the armature (and regulator?)
The fan extension dis engages that side load from the generator bearings and makes the geny more reliable.
Just make sure that when you have the geny rebuilt, that you pair it with a good (new or tested) regulator. When one fails the other is usually a casualty as well.
If you go over to Lucas bits, it will all be easier where you are.
If its just brushes and bearings it is easy enough.
The alternator is reliable as, but you will need a very small pulley to turn it fast enough, and then the belts will likely slip because it takes a lot to drive the big (important) fan.
The fan is also a weak area, so check it for cracks etc. while you are in there.
