Do I need to drop the motor/trani to replace my alternator? If not, advice?!? (IMG:style_emoticons/default/confused24.gif)

no way get it from underneath. If you have a 75 76 you will have to remove the heat exchanger. If 70-74 just the left heater plumbing

Nope.
Rasie the rear of the car as hgh as you can get it. remove the drivers side wheel. from under the car, remove the dust boot that goes to the fan to the alt. Follow the wires from the Alt to the relay board in the engine compartment. Pull the top off the board and remove the alternator wires from the relay board, and the wire that goes to the starter. go back under the car. You will see a bit of engine tin that goes along the shelf. it is divided in two sections. A long section and a short one. Remove the short section of tin. there is a hidden bolt on the seam near the engine shelf, feel for it. Now release belt tension on the alt. You may need to get a star point nut driver for this. If so, go to true value or HD and replace these bolts with regular metric allen bolts. remove the alternator belt. Plan on replacing it. Alternator is held in with 2 m8 allen (or soon to be replaced star point) bolts. Take them off. One of them is already loose, since it is what you loosened when you released tension on the alternator belt. You are still under the car, try not to let the sucker fall on your face. Its heavy. Now, find whatever I have forgotten about, and unhook that. Wiggle the old alt around till it out of the car. Again, you are doing this from under the car, don't let it fall on your head. Thats it. Buy a new one and replace everything. Easy. Zach |

I've done it both ways and i have to say, dropping the engine is quicker.
There's just not enough room up there to work, even with the car on a lift. It takes twice as long as dropping the engine. (IMG:style_emoticons/default/popcorn[1].gif) Andy |

I've got to do this as well. Anything wrong with having my unit rebuilt, or should just I replace it and forget about it.

I can swap on an early car in about 1 hour. There's a write up here.

(IMG:style_emoticons/default/popcorn[1].gif) Andy Geeeezzzzz, Andy. It takes 3-4 hours for most people to R&R an FI engine, and .75-1hr to replace the alternator in the car. For the original poster, BE SURE you check the length of the B+ stud! Adjust as necessary to clear the rear cover of the alternator. The Cap'n |

anytime you buy a new alternator get the higher amp one made for the 912e.
Or don't but I do. |

Yes, your electrical rebuild shop should be able to make a higher amperage unit for you (which is a good idea) (IMG:style_emoticons/default/idea.gif)
I found it goes a lot quicker if you have another person (who knows what the job entails) doing the top-side stuff while you're under the car doing the bottom stuff (or vice-versa) (IMG:style_emoticons/default/unsure.gif) |

I'll pick you up from the airport when you fly into Boise, Idaho! What time do you arrive? (IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/lol-2.gif) Actually, thanks to all that provided insight into replacing my alternator. I hope to get some time to work on it in a couple days. Brad |
