In the past I’ve rebuilt more starters than I care to count, but with that being said I very seldom rebuild them anymore. Due to the price of parts and labor rates, I have found that replacing the starter is cheaper in the long run than rebuilding. If you still want to go that route this manual should help you out. Check out section #7. https://www.mymowerparts.com/pdf/Ko...urage-SV470-SV480-SV530-SV540-SV590-SV600.pdf
Check it is not the wiring on you mower by jump starting off your battery directly to the starter motor , both the + & -
Check that it is not your battery by doing the same using your car battery ( car engine off )
Nine times out of ten the problem is a bad battery cable or dirty grounding point.
AFAIK, Kohler do not sell starter parts so you need to get them from an auto electrician.

Try berts tests. If the starter is really pulling too many amps you probably can't fix it. True high amp draw is usually shorted windings in the armature.
I took the starter apart, 600 grit polished the commutator, and put back together. Now it drops the battery voltage to 9.0V and barely starts the engine. But it does start it.

Did you check for the mica between the commutator bars for about .020" undercutting?
BEfore you do that double check the mower battery leads by jumping to the mower battery terminals .
A battery will be cheaper than a starter but make sure you fit a mower battery or a motorcycle battery & not a general car / truck battery.
And put a sealed one in there .
Mower batteries are physically stronger inside to compensate for the lack of suspension and the excessive vibrations.
