I like to take things apart and my starter wasn't working, so here it goes:
Tools:
6, 8, 13 mm
Contact cleaner
Lots of shop rags
Flathead is helpful
Take out the four screws on top (6mm and 8mm) and everything kind of falls apart.
top comes off revealing the brushes
If you haven't already, unscrew 13mm bolt holding positive brushes on and the brush assy will lift up.
the cylinder is also loose
the cover of the gears may fall out
[edit] notice the ball in the hole between the gears, per hsfdfireman671 [/edit]
This is what a broken magnet will look like and do (ouchy)
I had a rusted starter lying around so I was able to swap out a good magnet but the whole cylinder had to be deconstructed and cleaned. Bend the edge of the metal retainer just enough to slide the magnet out. It may need some force
Then clean it all up nice like
and reassemble
n.b. If you take all the magnets out they MUST be reassembled in alternating pattern of positive and negative. I simply used one magnet to find out whether each was pulling or pushing.
Clean up the armature (the big round inner piece surrounding the axle, mine has a dent from the broken magnet). I used a wire brush and contact cleaner.
I have read that it is also a good idea to clean between the ribs of the commutator (the copper end). I don't know how much of this is recommended but mine was VERY dirty so I had to clean it up somehow.
I used a screwdriver to release the bottom gearing from the plunger and cleaned everything up
And begin reassembly
Now for the brushes. The copper colored oval holding the brushes in easily slides out once gently lifted above the posts holding it in on both sides. Below you can see the bottom right brush is worn down.
New brushes go in (i found mine on ebay)
And my favorite part: stuff a 24mm socket on the top side of the brush assy and it just slides right onto the commutator.
Carefully reassemble everything and then test it out. Positive on the inside large post and negative grounded out will spin it.
Move the negative to the small post and you should hear the plunger engage the axle.
