I changed out the cam roller on the hydro of my 916H today, I thought it was steel but it was some sort of rubber.
I made the mistake of changing it out in my shed and when I cranked it up it ran into my tiller. Couldn't find neutral at all. I got out my manual and tried to adjust according to instructions. Lining up with the neutral mark was about as precise as throwing baseballs at a clown in a dunking booth. I finally gave up on that and started using the wear marks at the adjustment bolt and finally got it to where there was no creep when the lever was pulled to the backside of the neutral gate. The problem is there is at least 3/16" play front to rear in the gate.
I can't move the lever that much without activating the hydro motor. If I push it to the front of the gate it creeps forward but is absolutely still at the rear of the gate. I don't know why they didn't just make it with a single point ball detent.
I went back out and tried adjusting again using the adjustment nut on the cam cross shaft. As little as 1/8 turn of the nut clockwise or counterclockwise would start engagement of the hydro motor forward or reverse. I finally settled on a point where the hydro starts energizing forward and reverse at either end of the neutral gate. I am thinking of modifying the shifter sector with a sliding bar so that I can adjust the neutral gate to match the narrow neutral range.
