Ditto what rusnak said, there are 6 nuts, 3 hold the plastic shroud on, the other 3 do not.

There are 6 nuts on the end of the 6 Phillips head bolts. 3 hold only the air shroud. I use a short 8mm wrench on only the 3 that hold the shroud. Then you can pivot the alternator and remove the wires, then the housing.

OK me stuck...I have the whole bloody thing out but does the fan shroud come off the alternator? (I have the fan off no problem, alternator out of car with shroud)

3 nuts for the air deflector off

3 nuts for what I thought was the shroud off

tapped (pretty good) and nothin....I mean nothin! - so how do I get the shroud off?

I'll post a pic BRB

greg, the little plastic thing is held on by the 3 shorter studs (nuts) watch not to drop the washers

ivangene

now how does the alt come out of this?????
nuts removed?


and...????

Ed Hughes

Put nuts on the ends of the studs and gently tap it out. Once they're free, remove the nuts.

ivangene

got it Ed, Thanks!

I thought of that but thought "you know..maybe I should ask first rather than ask 'now what, i broke it' later"
alt heading to the shop monday - she's puttin out over 17 volts and might have cooked my battery, caught it early so maybe I got lucky, maybe not

"Put nuts on the ends of the studs and gently tap it out."

Not a good idea, especially for the 5mm studs.
Best approach, as for all Porsche alts, is to use a 2X4 or a 4X6
block of wood on the floor and tap the alt housing on the block
and 'shake' the alt out of the housing, i.e. the housing is
rotated between taps on the block of wood. Any other way
either damages the studs (soft which bents easily) or the alt case.

Note: Many of my 'seasoned' mechanics still use the 'hammer' approach.

I'm not sure that I'd slam my alternator on blocks of wood, like a crack mom dishing out some post natal shaken baby syndrome.

Gentle and persistent tapping works for me. You'd be surprised how effective it is.

ivangene

well I PB blasted it and let it sit for a while, then rapped on the center of the alt with a dead blow a few times and stopped...then when Ed said hit the studs I supported the shroud right close to each spot I was tapping on with a 1-2-3 block on the shroud so the energy was local and right on the ring, not on the fins...I worked back and forth like torquing wheel nuts and used very little rapping with a medium sized metal hammer and a brass drift 1" diameter and the nuts were completely flush with the stud so I had max area and neither the nut or the stud was taking all the blow

I didnt just hammer the studs without some thought and adequate tools....

Ed Hughes

I see a lot of cracking shrouds these days, hence my approach. I'd rather deal with something happening to the alt than putting more stress on the shroud.

ivangene

any tips on cleaning the bits...just clean, clean and polish, paint, clear, leave it dirty

Thanks guys for the tip. It was easy to get off with just the three bolts.

Now for next steps. The alternator looks pretty rough so while I am going through this effort I might as well have it rebuilt.

Questions:

1) Who is reputable for a rebuild? Can any alternator shop do it?
2) Two of the rubber boots need replacing on the wires. The ground wire boot disentegrated right off. Is this a standard part I can get from Pelican or is there a better source?

ron mcatee

Greg, I hope you disconnected the battery prior to alternator removal. The hot wire can do damge if it hits any metal object and grounds out. You can have the housing and fan bead blasted, but do it lightly. Then you can paint it, polish it, clear coat or whatever you like.

Ron,

Yes battery is actually out of the car and waiting for the new one to be put in.
