When I do not like my choices on a project or the fix is not good enough, I take a time out from it and do other stuff. The problem then just gets tossed around in my head.
What has been holding me up on getting the bypass adjusted correctly is that the holding valve will make it nearly impossible to get to the bypass cap nut and the lock nut. You must be able to get to these. My solution is I am going to have rubber lines made to use to the drive motor from the control valve. The cost is not the end of the world. I have a pile of various hoses that I may have a way too long hose in. But too long is always better than too short. In fact, hoses that are too long are easier to move out of the way.
I will report back after I get this part done.
I ended up painting more parts. I used the ag implement spray paint from Tractor Supply. Then, I clear-coated it with an enamel gloss clear coat from Rustoleum. It looks quite a bit nicer. But. Nicer, as in shiny, means nicer, as in painting steps. I had to wet sand the color coat, respray the color coat because I sanded through to the primer, and then apply several coats of clear.
Now, I have three topics in one thread. I may fix that. I will have to use my big monitor and two windows to cut and paste. I really learned a lot about the banana plate and what needs to be done for a trouble-free installation. I did the same thing with the garden tractor and the jumpy tractor linkage. You could go back to casecoltingersoll and search for ssmewing. There was a point that I changed to inline joint because that was what everyone said you needed to do to fix the jumpy tractor. You will see that I did not like the inline joint much because the ball and socket were too small. After I messed with that for a while, I still had slop. So I laid under the tractor and kept moving the lever and watching what was happening. I had a revelation. It was the travel control lever washer being worn out, I was the one that at first said that needed to be changed with the inline linkage. Then, I say that the linkage was also moving in the travel control lever tab for the linkage. That was how the special linkage was born.
I did not find a need for a special linkage in the loader speed and direction system. Case added the bushings and solved most of the issues. However, the system has to be installed 100% correctly, or you will have installer issues unrelated to how the hardware was designed. I installed and uninstalled the plate and bracket several times. My plate had a worn-out bushing at the pedal control rod. That was caused by the mounting bracket not being 100% square to the direction control lever and the follower bushing in the slot in the plate. Those two things must be in perfect alignment. The follower must stay in the groove from one end to the other. Mine was not doing that. The plate was too high at the bracket end. The only way I could fix that was to square up the bracket in my vice and a 10-pound helper with a handle on it. If this had been how I adjusted it, that bushing at the speed pedal pin would still be fine. My speed pedal pin is smooth and is still a perfect, snug fit in the bushing hole. The bushing was not in good shape and was close to coming out of the plate.
The other parts that need to be right are the washers and the BUSHING, which are part of the pivot of the direction control lever. The control lever cannot move around at its pivot point if you want full stroke on the spool in the control valve.
The last observation is that the washers used with the joints with a cotter pin must be thicker than average and have the same diameter as the follower. You cannot have a gap where only one side has full contact, and the cotter pin side does not, and there is space to move on the pin due to a washer that is too thin and too small in diameter. That also caused issues when I was working through things.
There is the whole story from a guy who likes exactly right as my accounting professor taught me. He was also right that I would be good at accounting. I ended up owning a business and should have been an accountant/advisor. Numbers do tell a story, and numbers do not lie.
