3b alternator part #? (1 Viewer)

[Tom Ellison]

Hi,

I have a 76 40 that was converted to a 3b diesel by the PO. I believe the alternator has given up. Can anyone provide me with a part # for the alternator? The 3b is a 1985.

This from a 1985 BJ42 GENeral market van 3B 4 on the floor Complete Built Unit WithOut Roll Bar.

Note: This is without the vacuum pump.

I believe the part number for the alternator with the vacuum pump is $$$-$€£¥... Was cheaper for me to buy a parts truck!

You do not have enough money in your bank account for a new one.

Alt rebuilds in Tucson are $75-$100 ($93 for 12v 1hdt/1HZ last month w/ rectifier)

Find a local shop.

Have you tested the regulator and/or checked the brushes? They are simple and comparatively cheap to replace.

Thanks for the replies gentlemen. I decided to have a local shop rebuild it.

If you are having them tear it apart, have them replace ALL the diodes, not just the ones found to be defective. The cost of the diodes is minimal compared to the tear down and re-build cost. When mine died the first time, they only replaced half the diodes because only half the diodes were in need of replacement. 11 months later, the other half needed replacement and I had to go through the whole process again.

Great suggestion MrMoMo. Will do. Thanks!
