:eek: Starter just spins, took starter out everthing looks good and tests fine. coil's good Primary wire good and hot, condesor good, points good, rotor good, battery fresh,, before I took starter out turned on ignition button , Starter just spun and not engaging fly wheel , teeth on fly wheel all thier. so i'm confused help me out, Cheers BIG MIKE
 
Teeth on starter is good , no metal shavings, whe I pulled starter out the drive was out from the starter itself up against the spring, all metal and spring looks great no chips or wear.
 
If the battery is low, or connections bad the starter will not spin up fast enough to spin in the drive, if the drive has grease on the screw threads for the pinion it might move too stiff to engage ==try cleaning it, only light oil for lube ---some have a little pin with a small spring to keep it from vibrating down the threads while running ---that can stick, how easy does the pinion turn on the thread??
 
Bendix is Fine bolt is not sheared off. Battery is Fully charge. I just cleaned it up will put back in next week let ya'll know what happens Cheers BM
 
just checking if this the correct position for istalation of my starter.

Mike, Make sure the threads on the shaft that the Bendix gear rides on are clean and very little if any light oil is applied to it. Also, while you have the starter off the motor, look in the hole and make sure that you haven't sheared any teeth from the flywheel. Ken
 
Thanks Ken I will do that. I did feel inside thier yesterday as much as my hand would fit every tooth felt ok, but will check again. thanks Mike
 
You could try cranking engine over by hand to a diff spot on the flywheel(diff teeth) and try it again if you can't find anything wrong with the starter.

I did just that before i took out the starter, Starter just still spun, flywheel is attached not broken. if it did break(flywheel) then the flywheel would have spun freely aswell. the 2 bolts on the bendix spring are securlly attached , no rust, nice and clean. the pic I posted that what the shaft looked like when i pulled it out. is that the same postion when i reinstall it? or does the drive come closer to the starter. Mike
 
Pull the gear very lighly and see if it binds.The starter has to slide toward starter to engage flywheel.Had it happen to me.If it does it again, if thats the problem swap it out, junk
 
Mike, I would remove that spring and double check it before you reinstall the starter. Sometimes the break is hard to see. Your picture is the way the starter will look when you replace it in the housing. You may have to 'fidget' with it a bit to get it to clear the flywheel but you'll know when it is in. Also, now is the time to put that hangar on the front of the starter that bolts to the pan on a pan bolt. If you don't have one, Macs and other suppliers have them. Ar you running 12 volts? Ken
 
Did I not read somewhere that if you put a late model v8 spring in will turn wrong, I see this is a 12v did you build it or have it built, check the spring there was a post on this months ago
 
The pic is not my starter , it was an example of one to see if it goes in correctly , My system is all 6volt witch i like and may change over to 12 v in future. the spring on mine is fine I took everything off to clean it all. I think it (motor) was cold but i did hand crank the motor for 5 mins before i started anything. Cheers Mike
