alternator for 89PT40

[mbulriss]

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.
