any tricks to take pulley off alternator?

Hello, All!

Hi, they sent me an alternator with the wrong pulley, so I have to swap the
old one. I started to take the pulley off the new one, but it seems
difficult, using a screwdriver to hold it from spinning. Anyone have any
tips?

Thanks

AFAIK, you can't do it without a wheel puller tool. At least, I never
managed to.

What year of car is this going in? For my MkI VWs, I just used an
impact wrench to remove the nut and then the pulley fell off. You can
also jam a screwdriver in the fan, but that is easiest when the
alternator is mounted in the car. Out of the car, you might use a huge
clamp clamped to the body such that the clamp will keep the fan from
spinning. You could also get a big U-bolt to go in a mounting ear and
interfere with the fan.

I,ve used the jam a screwdriver and the impact wrench. Highly effective.

I hit it with an impact wrench, leave the nut on just the top of the thread
then hold the pulley in my hand and strike the nut inside with a hammer.
Works like a charm and the nut catches the alt before it hits the floor (or
the bench). Of course a vice and a socket extension might be easier for
the striking part if you're not as gifted in the hammer eye co-ordination
department.
