You can simply remove the input gear for the high speed gear stage. That is the easiest way.

We are testing this now to see the max loading the ball shifter can still shift into neutral. My theoretical calculation indicates in excess of 400 lbs in a 2" diameter winch.

Paul: Just to confirm: Are you saying the recommended stock 3/4" air cylinder will shift the winch with the 400lbs load consistently / reliably or should we be upgrading the cylinder size ?

Having said that, I would be surprised if we are over 100lbs.

Thanks

I would remove that gear completely and just put a spacer in there. The only resistance you should have is the rolling resistance of the two bearings and the resistance between the bushing in the remaining gear and the shaft. This should be nothing compared to the load the bungee (or whatever you are using) will be to shoot the ball.

We are seeing a great deal of resistance as well. For example, when a motor is not present in the gearing the shaft is very easy to turn with only two fingers. When a motor is present and the gearbox is in neutral (made by removing the low speed gear) the shaft can't be turned by hand by some of our smaller students and takes a good deal of force from anyone.

Is this normal behavior or are we missing something?
