How do you change brushes and bushes of a Nissan 1400 starter?

Get under there and take the whole thing off. Undo the 2 main bolts that are 14mm.

disconnect the battery red cable. easier to take it off the battery and pull the whole cable out with the starter motor. Then start taking the large cylinder apart. Be a bit careful not to drop stuff on the floor because its all compression held by the 2 long skinny bolts.

I've gotten as far as getting the brushes out. Now need to get the right replacement kit because the auto parts guy sold me the wrong stuff.
