How to NOT remove a pulley from an alternator: a tutorial. 1984 300D - PeachParts Mercedes-Benz Forum

I just nabbed a 115A unit off a Saab Saturday for $10 (half off day)....and, it is not even 2 years old (date stamped 2007)

They pretty much had it installed, and junked the car not too long after, the brushes/regulator are nearly 100%

As for getting off the pulley/fan, an impact of any sort works great. I use a Harbor Freight 1/2 drive 12V Digital Impact wrench to do that sort of stuff......pulleys, allen bolts inside the hub/rotor assembly.....etc. Works great. Not bad for $49 It even comes with two double sided sockets (one of which fits alternators)

Ditto on the 12 Volt Impact Wrench I have at least 4 of them. I keep 1 in each vehicle. They are made for tire changing but work almost like an
Pneumatic Impact Wrench without the need for an Air Compressor.
I have not bought one for awhile but when they were on sale at Harbor Freight they cost around $22 each. It also speeds up Tire Rotation.
12 Volt impact below used when I took apart my Alternator and changed the a Bearing.
