It shoud be very easy to do. If you look at the diagram Ducky posted all they are doing is seperating the feild coils. On most starters the feild coils are hooked to one terminal. Here they seperated them. Put power to one wire it goes one way put it to the other and it goes the opposite way. You will need a relay and a on-off-0n switch. Look at the wiring diagram under manuals for a Massey Ferguson MF10 power lift it shows how to wire it.

I was wrong about the diagram, it is different for starter/ generator, but on a reversing motor the feild coils are seperated.

Ducky,
I looked on the Surplus center site a few days ago and did not see this motor.

This motor would probably work. As the gearing is set up now it would take about 1 minute to rotate the 180* which is a little slow but still workable. I could go to a larger sprocket on the motor end but that would increase the torque needed which would slow down the rpm. I would have to fabricate an adapter but at $75 it might be worth trying.

Thanks,
Bill

If you look at the torque of the motor you can increase the ratio at the output and get a little fast response at the chute.
Think about this for a moment.
If yo torque a head bolt on a small engine to 27 in/lbs you can get a feel for the amount of torque this motor has.
It should turn most anything you want. Remember Grease is our friend.

I bookmarked the page on Surplus Center last night and when I went in to order it the message said the item is discontinued or no longer available on the internet. There is a phone number listed that I will try later today but will probably not get answered until Monday.

Thanks,
Bill

At the surplus center, U must check to see if it is in stock b4 U order it, because when
they're gone they're gone! Ford has a strong power window motor with worm-gear drive that would work. If motor runs but output gear doesn't turn, take plate off
around output gear & U will find 3 plastic balls that are split because of age. I replace
balls with 3/8 dia.x 3/8 long pieces of delrin plastic. They last forever.:smile1:

I used a window motor from an older GM, seems pretty strong. Adapted an old worn out wrench then a socket to connect to the motor.
