Any idea of what year of Toyota and model features that starter?
Man, I wouldn't know what exact model and year to give you. I've seen them in many of the Toyotas when I go to the auto yards. I took one once not knowing it had gears inside. I've seen it in Camry's for sure.
i believe all car starters do that. even tractor mower. youll just need a big flywheel to mate the starter gears to
No, not all the starters have reduction in them. I have several car starters that I've removed but only the one from the Toyota has the reduction.
Look at this: One's for a Nissan and the other is a Toyota. The Nissan has the motor's shaft going straight out and the Toyota has the motor on top and the solenoid on the bottom. The area in front of the two is a gear case. I don't think it's a LOT of reduction because the difference in the gears isn't much, but I think anything would help you out.
