Disassemble alternator
Since my Z is down waiting for it's new motor, I am wanting to dress up the engine bay a bit and was thinking about painting the alternator. Is it difficult to split the case and remove the armature so I can paint the case and then reassemble? I want to clean the case first obviously and dont want to saturate the alternator with cleaner and water. Hence the reason I want to disassemble the alternator. Any advice would be appreciated. Dont want to go diving in, get it half way apart and then go - oh crap this aint going back together. LOL!
Thanks in advance!

It's been a while sence I have taken one apart but I believe the hards part is getting the pulley off and back on when done without damaging anything. The rotor has two electrical brushes that are spring loaded. There is a hole in the rear case for a paper-clip wire to be used to hold the brushes in place while putting it back together.

If I remember right the stator wires need to be unsoldered and that requires a soldering gun not a low wattage iron, too much heat too long will ruin the electronics. The pulley design uses an allen wrench in the center of the shaft and a ground down box wrench or open top socket wrench on the nut. If you can't remove the pulley nut then just degrease with a rag and solvent then paint as assembled. I sanded and polished mine and painted the stator laminations so it had to be taken apart, except for the above it is similar in construction to older alternators.

Since your in Indy, I just had an alternator rebuilt at Stan's Auto Electric. Their at 5115 E 30th St. Call 545-8537 and ask for Charles he'll pull it apart for you. You can do what you want to the case and then he'll re-assemble it for you and test it. I had a S-10 alternator powder coated. Mine had the soldered coil in and I didn't want to mess it up. In testing I found out the coil had been over heated and it was giving readings all over the map. Looks super now.
