Alternator/Fan Removal problem

[rubenmad]

Here's how my alternator looks. I removed all six nuts and it will not come off the housing. Do I need to remove anything else? Do I need to continue banging on the bolts?

Thanks in advance,
Ruben

Hi Ruben, I recently did a R&R on the alternator in my '82SC. Fortunately, the alternator came out of the shroud without any problems. There is a good tech article you can get to from Pelicans home page. Look in the 911 tech articles under electrical. They actually say to tap on the bolts with a wooden mallet, then seperate the alternator from the shroud. Good luck.

Put some nuts on the studs across from each other. Don't put them on all the way, just enough so they take the hit and you don't damage the studs. start tapping the nuts going from 1 side to the other wroking your way around. It will come off.

Hey Mark, the beast project is looking great so far. I'm very envious, not only of the car itself, but of your skills at building such an awesome car. Keep us posted of your progress and be sure to post recent pics.

That housing looks pretty corroded, so I would advise putting some penetrating oil down all six mounting bolts, and let it sit overnight ... before doing any banging! A plastic mallet also does well getting those stubborn bolts loose. Jusy so you don't get too agressive with the pounding, I suggest holding the housing between your legs while wearing jeans. The bolts and housing can probably take a bit more pounding than your knees can! An upside-down cardboard box can catch the fan and alternator, and hopefully it won't be damaged!

Turn it over!

Remove the fan nut (will probably already be off) and then the fan (it will come off just by rocking usually). Once the fan is off find yourself a piece of 4 x 1 (approx) timber large enough to fit across the housing. Drill a clearance hole for the alternator shaft in the centre of the wood, place it over the shaft, refit the nut and tighten - this will pull the alternator out of the housing. You may be able to pull the alternator off with the fan if necessary by adding extra spacers between wood and housing.

Don't hit the 6 bolts - they are too waek and may cause further problems.

Good Luck

My housing was a pain to get off also. A fellow Pelican poster gave me this simple tip which actually worked great. I would have never believed it as hard as it was to get off.

Put 2 pieces of small 2x4 on the floor just far enough that the outer edges of the housing rim stop it from touching the floor on opposite sides. Then pick up an end while leaving the opposite end still on the 2x4 and let it drop a few inches onto the 2x4. Keep working back and forth on opposite sites. Mine eventually fell right off.

Good luck!

position it just like your picture. grab the housing with both hands. repetedly knock the housing edge downward onto a block of wood or several folded rags. swap sides every couple of blows. inertia does the work. that's how the pros do it.

Ruben,

I pulled mine to change the brushes (highly recommended if you have high milage) and decided to clean it up a bit, but also could not budge the 2 parts. My solution? Clean it with a wire brush and put it back in the car! I didn't have the time as the car is my daily driver, but WD-40 works well. Spray down the studs and let it sit.

Perhaps I'll get eager to do that great detailing paint job when I have a weekend where I don't need the car!

I recently had the same problem. My Porsche mechanic recomended pressing it out rather than pounding or "tapping". I used a small hydraulic jack, some blocks of wood and the weight of my suv ( they are good for some things). It came off easily. It wouldn't budge with the hammer method. Good luck.

Thanks for all the input!!

I just finished the work this morning.

Check out my fan:

Hello

Tapping on the studs should be very carefully as those are the end off evry long and soft screws and they can be easy bend or get deformed threads.

If they are bend then better cut and use said techniqes or if the alternator is to replaced then screw them out from the frontside.
