First thing to is to check out the price of a new starter motor, There is no point repairing the old one, if it is going to cost you more than a new one.  To buy a new starter, please contact: sky@motor-starter.com

A faulty starter motor can sound like a flat battery, the engine turns over slowly or not at all, sometimes you can see the battery terminals and leads smoke or get hot due to the high currents been drawn by the faulty starter. First thing, check for other faults. The best way to check the battery is with a load tester but these are expensive, and there are ways around it.  Put a volt meter on the battery, it should read, around 12.6 volts.  If it is as low as 12.2 volts then charge the battery. Check battery cables are clean and tight and in good condition. If all is good then the best way to check the battery  and starter motor is to remove the battery and put it into another  vehicle. If the fault moved to the other vehicle, then you have a problem with your battery, Charge it or replace it . If you have eliminated everything else chances are that the starter is faulty.
      If you can get to the back of the starter. This can be helpful if the starter is completely dead, not clicking or anything and can help diagnosis a wiring issues with the vehicle or a dead solenoid. 
First thing to do when doing any repair that involves the high current cables on a motor vehicle is DISCONNECT THE BATTERY, if you skip this step you could end up injuring yourself or setting the car on fire.
Some vehicles it is easier and quicker to remove items that are in the way, rather than try and work around them. I removed the clutch cylinder, battery, O2 sensor cable and cooling fan, this didn't take long and made the job of reaching the starter bolts and physically  removing the starter much easier and required much less swearing.
On this car is was the battery cable and solenoid wire was removed from the starter after it  was pulled out. On many vehicles you should do this while the starter is still bolted on.

Now that you have it out find a clean work area and a container to put all the bits into. Now would be a good time to clean the outside of the starter, I just wiped it over with a petrol soaked rag, so its not all that clean
Make sure you mark the case and solenoid the  so it makes it easy to resemble as some parts can be assembled around the wrong way.
1. remove the 2 screws that hold the back cover and brushes in place
2. remove the clip and spring
3. remove the heat shield
4. disconnect the motor cable from the solenoid
5. remove the long blots that hold the motor together
6. remove the brush cover
7. carefully unclip the 2 brushes that are attached to the field windings by pulling back the spring and removing the brush.
8. remove the brush holder
9. remove the field windings
10. unbolt the solenoid and remove the armature and solenoid together
