450 Starter...bad news from shop

Ok, I got a call from the starter shop today, first the tech asked me to confirm the voltage of the starter. I told him the starter had been working but seemed slow, then asked if if was gonna be a quick fix. The tech said that the field's were burnt up and it was gonna take some time. I asked what was it gonna cost me and he said he didnt know yet. That was not what I wanted to hear. I had to google the field's in a starter, still not sure exactly what's burnt.

So what caused this and how bad is it? I'm tempted to call him back and see how much it'll cost.

Gene, what part are you talking about costing around $40? The tech told me when I dropped off the starter its $84 plus parts...so I'm probably gonna have close to $200 in it I think.

Early 450 gas was 6 volts, and later ones were 12. Easy to tell when inside the starter which is was as the 6 volt starter has two field leads soldered to post and 12 volt has only one lead. All four field coils are hooked in series on 12 volt if factory starter on 450. If that tractor is now operating on 12 volts I would surely put the 12 volt field coils in it along with proper end plate or just trade it for a rebuilt (as much as I hate rebuilt starters).
 

Tom, its a 12volt gas 450. When the tech said the "fields" are burnt I should've asked him exactly what he meant. I'm not sure which part he's talking about.
 

Pete, where can I price a rebuilt starter? I'm wondering how much a rebuilt one would cost.

Next, what caused the field to burn? I turned her over no more than 5 or 6 times, 3different times while trying to start her. Is it just a 60yo part or is there something I need to look out for?

I just looked at Hy Capacity to check on starters and they don't show a 12 volt starter for a gas 450. I guess not enough of them around. The 6 volt was right at 300 bucks. The fields (I would like to see them) would only burn out from extended use like cranking and cranking for a long period of time or excessive voltage drop will get them over heated also. Usually what happens is they burn the solder out of the stud but that is easily repairable.
 
field coils he is marking up the price a bunch. Call Harvey Bros for a rebuilt they are the best in the business. Same old story some starter shops are better than others your problem has went on long enough and should have been solved the first time.
 
that is how most starter problems happen... by trying to start the tractor with a low battery, and keep trying and trying causes the starter to get hot and burn fields or wires and melt soldered joints on terminals and armature. if it dont crank over then just leave it, and charge the battery. just finished working on the very same starter.
 

Gene, I'm not sure what the cost'll be, other than he said $84 for labor and whatever parts cost. I'll definately hang on to the info you gave me. This shop iis the only alternator/starter shop in 100 miles and has this area sewn up.

I thought I knew what I was doing...I thought wrong.

Sounds plenty reasonable to me.
 
Is this what the starter you have looks like, two screws in each field polepiece, for a total of 8 countersunk screws?

(Field coils are #17 and #18.)
