Well i have been off work for a few weeks now and have got a boat load of jobs done on the car. As always i tried to take as many pictures for you all. Day by day i will try and do a write up of each little project. Fist up is how to strip and clean a starter motor, handy to know if your starter is sticking like mine is.
Obviously you gotta remove it from the car, i covered this in an earlier post. The starter consists of 2 main parts, the solonoid and the electric motor. The solonoid basicly makes the shaft shoot out and engage with the flywheel to turn and start the engine. First you gotta remove the solonoid. This is held on by 3 cross head screws. Be carefull not to strip the screw heads, make sure you use the correct size screw driver to avoid this. Before you undo them disconect the wire that goes from the solonoid to the motor.
Once the screws are out you can simply split the solonoid from the casing, there is a spring inside which you must not loose.
Try and hook the part that is left attached if possible. If you cant unhook it dont worry cos you soon will be able to once everything is loose. Next undo and remove the 4 bolts on the opposite end of the motor and remove the cap. Now would be a good time to clean the cap and re grease.
You now need to slide off the circlip that is holding the shaft in and remove the end cap from the casing shell.
You should now see the following. You need to slide the electrical unit up and out to remove, being carefull with the carbon contact blocks. Make sure none ping off and get lost or damaged.
The next task is to slide the whole centre shaft assembly from the casing. At this point its simply held in by magnetic force, so pull and it will come out. You may end up with something similar to this.
Because mine came out with magnets all over the place i needed to clean it all and re assemble. To do this slide all magnets out of the shell. Slide! Do not attempt to lift them as they are brittle and may snap. Once the shell is bare get a wire wheel inside and clean up all rust from the inner face. Once clean slide the magnets back in and re-fit the circular cage that holds them in place.
Next turn your attention to the centre shaft. You need to clean up the contacts on the end. I used some wire wool as its not too abrasive but does the job nicely. Here is the before and after shots.
Nearly done! All you gotta do now is put it all back together. And yes youve guessed it re-assembly is simply a reversal of dis-assembly. Its not that hard really. I came accros a couple of tricky parts which i will list for you. Once you have the centre shaft back in place and the electic contact assembly in and the end cap back on you may wonder how this plate on the opposite end is supposed to sit. But dont worry because when you slide the long bolts back in you will see that it will only sit one way with the bolts slid throught the largest gaps.
Also you may wonder where about the rubber stopper is supposed to go. If you look closely you will see that there is a cut out on the casing that it slots into nicely.
Now your ready to attach the solonoid housing. Make sure you hook up the solonoid before tightening up all the bolts. I didnt and had to undo the bolts again as you have no chance hooking it on once tight.
Last but not least. Clean up the electrical contacts and re-fit the whole unit to the car. Fingers crossed it will be as good as new!
