How to reclock a CS130D alternator?

[farmer boy]

I have a CS130D alternator off a 1994 GMC safari that I want to use on a 1997 GMC K1500. The alternotor is the same alternator but with a different clock position, so I want to change it to work on the truck. Is this doable with the CS130D? If so, how? Thanks.

If you mean the back shell has to be rotated in relation to the front case, many can be repositioned - remove screws that hold unit together, rotate to needed position, screw back together.

To reclock alternator you have to pull the stator out of the drive end housing. Its press fit and you maybe able to get it out with some careful heat and tapping. Myself Ive only replaced one stator in one and it had a broken front housing so I just cut the housing and it lifted right out, then to go back into the new housing I froze the stator and heated the new housing and carefully tapped it in. If it were mine I"d either just buy a new alternator or extend the wires on the plug and battery cable to get them to fit. hth jstpa

Not sure you can re-clock a cs130 like was common on a 10SI. If the pics post, you"ll see why. If I recall GM mounts them in the normal position, not splayed.

Reason being, a 10si mounting boss (big bolt) in completely on one half of the alternator housing. On a CS130 your main mounting boss is on each half of the alternator, so if you reclock, you have to make some heavy bushings to make up the void. And you will want it solid to keep the pulley in line. I am trying to find a pic to show what I mean.

Hope this helps.
