Introduction

What you need

Step 1

              Alternator Front Cover

Remove 4, 7.9mm nuts using a 7.9mm socket driver head
One of the nuts is placed underneath the L-Bracket. Remove the L-Bracket and the 3 circled nuts before attempting to remove the remaining nut
There are two covers that need to be removed from the alternator. This step describes how to remove the back cover.

Step 3

              Removing the brush assembly.

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.
Avoid disconnecting wires unless otherwise specified!

Step 6

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.
These leads must be cut in order to remove the bridge from the alternator. These leads will have to be soldered back together on reassembly. Keep the cut as clean as possible.
Use wire cutters to cut all 6 of the leads on the perimeter of the bridge.

Step 7

If necessary, use a pry bar to gently raise the top of the bridge assembly off the alternator
Be extremely careful with the pry bar. Excessive force will damage the bridge assembly.
Make sure the cut ends of the copper leads are straight to make bridge assembly easier to pull off.

Step 14

You can pull the stator out of the remaining cover and examine it.
If the stator is scratched or damaged, you will need to replace it. Look for scoring marks or cut pieces of winding.
