1 is the armature windings.
2 is the commutator
3 is one of the brushes
4 is one of the magnets

In basic motor theory, current will come through one of the brushes, pass through the comutator contacts to the armature windings, continue out the other brush to a ground point. The resulting magnetic field will react with the permanent magnet, causing the armature to rotate. Because a new set of windings will now be in contact at the commutator, the rotation will continue.

In your case, there is a LOT of gunk that is doing its best to prevent proper conduction of electrons. :o

Wow, thank you for your insta-responses jimcor and Steve! :clap:

Your brushes are shot. Replace them and the springs...

How do you know my brushes need to be replaced? I googled "starter brushes" to see if I could get a picture of a good brush.. but couldn?t see any difference between the images on google (for instance this one) and my brushes?
 
Because of the amount of residue in your assembly and because even tho' they look fine they are considerably shorter than new ones. Plus the springs get week, besides we're talking under $20 USD. BTDT and got the T shirt. I did the clean up and less than a month later the starter quit again.

You might put it together and have it start just fine for awhile since you've cleaned it up, but trust me, replace those brushes and springs.

Point taken! :D
And the last (stupid?) question in this thread: Could I ride the bike without the starter??? :o (ordering time with my local Suzuki dealer is probably 2-3 weeks...:()
 
Hmmmmmmm, Does the 79 750 have a kicker? If it does you're good to go as long as the starter is in place. With it removed oil will be flung out of the open 'starter hole' in the case. Best of luck my friend!

I think the brushes look just fine and, as I suspected, your armature was grungy....but, it' not any more. If it took you a few minutes to get it out, I'd suggest you take a few minutes and put it back in. I bet it will start right up and work well for a long time. Just my opinion!;)
 
They do look fine. Trouble is they are not fine. They are worn. Had the same problem with my bike. Cleaned everything up put it back together and it worked GREAT! For about a week.

Steve, 'Planecrazy' can explain about the notch that develops on the back of the brushes that prohibits them from making contact with the commutator because of no spring tension.

As long as the starter is off, replace the brushes and springs and forgetaboutit for another 20 years.

JMHO :p

Jim, you may not remember this but I'm almost certain you and I went through the same discussion with the starter situation on my 1100. We could look back in the archives but I'm not that interested and I doubt you are, either.

In any case, someone thought I should change my brushes, even though the armature was an obvious problem and the brushes weren't an obvious problem. I didn't do it...I just cleaned up the armature and stuck the dang starter back on the bike. I'm not certain but I think that was about 10 months ago.......and I just came back from a ride where I stopped/started it 3 times.:-\\\

I certainly believe in maintenance but I never go beyond what I think is reasonable...especially with regard to a starter because, with the help a pretty girl (or a hill), I can start it, ride home and fix it. Just my opinion!:):)

(By the way, with the help of a fairly big girl, you don't need a hill.)

Yeah, I remember it. Guess this is just one of those things we'll just have to disagree on. I'm glad a cleanup worked for you, unfortunately it didn't for me. If I'm going to go disassembling the starter I'd put in the new parts just to avoid having to do it twice.
 
I'd say check if dealer has the parts, they're pretty common.
If he deosn't have them in stock, order them, put the starter back on and fix it for good once you get the parts.
Cheap price for piece of mind, and you support your local economy :D
 
I ordered 1 "Brush set", 1 "bolt set" (destroyed the head of a bolt when I took the starter apart) and 1 "O-ring set" from my local dealer. Probably 3 weeks delivery time... :(
And the dealer didn?t even know if the "sets" where 1 piece or two (1 or 2 brushes, 1 or 2 bolts etc). Total cost approximately $63...
 
Finally got the stuff I ordered, and I put the starter together with new parts today. I put the starter back on the bike, and prayed a little and pressed the starter button and - "click, click, click, click..."

A series of clicks, but the starter did not turn at all :(
I plugged in the battery charger, and tried to start the bike with the charger on, same thing. I left the charger connected to the battery and now I?m here, trying to figure this out. I need some help!

The starter could turn easily between my fingers when I had it apart from the bike. Any thoughts?? :confused:
 
Did you try the starter on the bench after you built it back up? I'd pop it back out of there and do a bench test straight from a 12v power source to see if it is actually working ok. You could try it while it's on the bike easy enough too, either short the starter solenoid or use a jumper cable or something, straight from the battery to the starter and see if it turns over. I'd prefer to remove it myself, just to remove as many "links in the chain" as possible
 
hey gents here's another thought a few years back (ok a lot of years back) i had this issue with my 750 and it turned out to be the one way starter clutch that is behind the stator rotor and easy way to find this out is to remove the alternator cover from the left side of the bike and behind the stator rotor there is a large gear that spins one way (i forget which way it spins) that connects to another gear that is on a pin and that gear connects to the starter
pull the pin that holds the middle gear and remove the gear
now try and spin the large gear that is behind the rotor it should spin freely in one direction if it wont spin freely in one direction then your one way clutch for this gear is shot
now for the bad news if the one way clutch is shot then there is almost certainly damage to the crank end if this is the case then
you'll have to replace the crank or get it spray welded and reground to spec
then you'll have to get a new starter ring gear a new one way clutch and put it all back together again

this is just a thought as to what could be doing it to him
and i know cause i had to do this whole procedure on my 750 i ended up replacing my crank as it was less down time for me and i rebuilt the engine while it was apart because it was the right time as it was all in pieces
