lt1 alternator rebuild

[Trans Am]

the alternator on the 95 t/a is making a noise that sounded like a lifter or something in the engine, metallic knock . At some point , probably when the underdrive pulley was installed , the alternator bracket got broken, the aluminium part that bolts to the front of the engine. only a little part of it where the bolt goes into the alternator , but it was enough to change the alternator position slightly and over time seems like the bearings in the alternator gave up.

its the higher amp alternator according to the rpo.

Is it possible to replace just the bearings? apart from the noise it works ok

Yes, I have rebuilt mine twice; once for bad brushes and bad rectifier, once for the rear bearing, they are fairly easy imho so long as you take it apart the right way; feed two paperclips into the tiny hols on the rear of the unit near and parallel to the axis of rotation, this will retain the brush heads (they can be a pain to get back into position if they shoot out, especially if they're worn) take the 4 case interlock bolts out, easy inspection.
