alternator for 89PT40

[Gus Rodriguez]

Mike, thank you both for the
information. I too am having charging problems. I recently
purchased this bird and am new to all of this. I will be asking many
questions in the near future because I have several issues that I would like to
address along with a general steep learning curve about Bluebirds. I didn’t
think about rebuilding both. I just knew that the one on top of the
engine was not working. The other one is putting out 13.2v at idle.
The one on the top is a Leece Niville by Prestolite part no. 110-573 stamped
150Amps. I don’t know what the one in the rear is but it appears
smaller. Should they both be the same? Also my dc voltage output
meter in the dash shows no output at all. The needle is well below zero
and does not move. What does the one in the rear power? (engine only?)
and is it metered anywhere?

Thank you again for your help.

Gus

Gus,



I agree with McMahan. According to my rebuild guy here in San Antonio,

you need to change them both at the same time, *especially* if you are

upgrading output. My rebuild guy also told me that the only

difference between the 145(150?)/160 Delco alternators was the

diameter of the front pulley. So if you go the rebuild route you

should be able to get new pulleys to upgrade to the 160 with the

existing cores. Last time I freshened mine up though, Ogburn's Truck

Parts had new ones on sale for a lower price than I paid to rebuild!

They didn't have the pulleys on them as I recall, so you had to swap

yours. The one under the rear bumper is no big deal to change. The

one under the bed can be a real challenge, Make sure you add all new

belts and seal the floor panel under the bed with new butyl or sealing

tape to prevent fumes from seeping into the bus.



After you fix it, come join us at the Lone Star Birds Rally in April.



Have fun.
