A month ago I bought a 1864 with 500 hours for parts to fix the noisy hydro on my 782. After replacing the hydro and drive shaft, I couldn't believe how bad it jerked when going from forward to reverse. The trunion had no wear except for the pin that slides in the slot. The pin where it was not worn measured .375" and the slot was .390", the slot on the original was slightly over the .375". After welding up the wear spots, filing them to fit and shiming everything, the hydro shifted pretty good.
Then I got to thinking there must be a better way to remove the slop and play. Then it occurred to me to use a spring to keep the pin from flopping in the slot. I tried it on the hydro that came out of the 782. I drilled a hole for the spring and made the bracket with the 2 holes to hold the other end of the spring. It seemed to work good so today I installed it on the tractor. Went to drill a hole in the trunion and found it is hardened. That must be why it was not worn. Went to plan B with the hose clamp, I figured a tywrap might not hold up. Wrapped it up and could not believe how well it worked. Super!!
The bracket is about 1"x 3/4" by 1/8" with a 3/8" hole in one end and 1/8" in the other. The spring is about 1-1/2" long, 1/2" dia. with .038" wire. McMaster-Carr part #9654K912 is close.
About an hour of work was sure worth it. This will work on all Cub hydros.
