Introduction
The objective of this repair guide is to instruct the reader how to remove and replace the stator in the CSC29 alternator. The stator is a series of copper windings that transfer current generated from the rapidly rotating rotor to the rectifier bridge assembly. This current eventually finds its way back into the car battery.
What you need
-
-
Pull cover off the body of the alternator
-
Once you have done this, you should be able to see the internal components of the alternator, particularly the bridge assembly that houses the rectifier, voltage regulator and brushes.
-
-
-
With the alternator cover removed, use a #2 Phillips screwdriver to remove the two, 6 mm screws that hold the brush cover in place.
-
Remove the brush cover assembly from the alternator. You might need to insert a needle in the small hole to separate the brushes from the rotor. Pull it out without using much force to avoid damage.

-
-
Use a #2 Phillips screwdriver to remove the two 6mm screws holding down the voltage regulator
-
-
-
-
Locate the copper leads connecting the stator to the bridge assembly. There are 3 sets of 2 leads on the perimeter of the bridge, making 6 leads total.
-
Use wire cutters to cut all 6 of the leads on the perimeter of the bridge.
-
-
-
If necessary, use a pry bar to gently raise the top of the bridge assembly off the alternator
-
-
-
Use a Philips #2 Screwdriver or a 7.5mm socket driver to unscrew the 4, 7.5mm bolts running along the outer perimeter of the alternator
-
-
-
Once the pulley is removed, separate the rotor and stator. The stator is the piece with copper windings.
