Alternator

[FordBroncoII]

I am installing a new alternator in my 1987 Ford Bronco II 4WD. I could not get the pivot bolt out and end-up pulling out the alternator with the engine mount bracket. It may seem simplistic to some readers; however, can anyone advise an easy way to extract the pivot bolt? The alternator is the original. The vehicle was running "hot" and "overcharging"

Also, I have conducted a number of internet searches trying to locate a new alternator wire including connectors. The part is apparently no longer manufactured. Other than a junk yard are there any other sources to check?

Thanks in advance for any replies.

I've been looking into replacing or repairing my alternator (also an '87 B2) due to poor output at low rpm's. I don't know exactly what you are looking for, but in my searches I have found these:

and on

http://www.napaonline.com/

look up your under alternator for you vehicle or for part Item#: ECHVRC441

I am still having trouble finding out if my alternator can be repaired (replacing the bad "diodes" responsible for poor low rpm output) by a simple change of voltage regulator or rectifier, which are available separately.

I opted to purchase a "new" alternator from AutopartsWarehouse.com instead of a remanufactured alternator, since I am trying to refurbish and upgrade the all the primary parts of the engine electrical system. No doubt other people have experienced the same situation. Replacing one or a couple of parts on older, original part vehicles potentially causes more electrical system problems. Ultimately, my estimate is that it is less expensive to install new parts to upgrade all the major engine electrical system components plus cables and battery terminals.

My original question related to something simplistic, The pivot bolt on the original, old alternator is not budging. Any suggestions on extracting it? In my relatively limited experience with the Ford Bronco II it seems to be the simple things that are the boondoogles.

With respect to the replacement parts for installation of a new alternator wiring harness, it is no longer manufactured, apparently. Advance Auto has one section of the wiring, but not the entire wire system.

Thanks for your reply.

If I understand you right, the pivot bolt is stuck in the bracket, correct? If so, it is probably due to a build up of corrosion. My favorite product for loosening up stuff like that is, "PB Blaster". Apply it liberally at both ends and let set for a day or so. Put the bracket in a vice and work the bolt with a wrench. You may have to use a hammer to whack it out of the pivot hole, which may unfortunately mess up the bolt threads. That isn't really so unfortunate, since if it is really corroded you probably should get a new one. Take the bolt to a hardware store and get a new #8 bolt.

Good luck,

Thank you for your reply,

I will let you know how the Pivot Bolt extraction goes.

Two more tips:

HEAT!!! Use a propane torch on the bolt and surrounding area. (Works best with some sort of nut loosening liquid.)

If possible, get a nut that fits the threads of the pivot bolt, ***** it on a few threads, leaving room for movement, and pound on the nut rather than the end of the pivot bolt. Might save the bolt.

Good Luck.

Well, I got the pivot bolt out, I had drenched it with 3 in 1 oil the day before I received the reply about the Blaster compound.

The pivot bolt does not appear corroded, but I think it had beeninstalled crooked.

I will use the Blaster compound next time.

Thanks again for the replies.
