cub 417 loader question

   / cub 417 loader question #11  
I have the 417 loader on a 7265. I took a couple of pictures hopefully it helps. This one is of the diagram at the base of the joystick. Notice if you push up past the detent it is the float position.

For some reason it is not taking the attachment. It is only 79 KB. Lets try the second one. This one shows the joystick in the normal position. The next one will show it up past the detent in the float position.

Here is the second picture at same angle as first. It shows the joystick past the detent in the float position.

Lets try the diagram attachment one more time. I also looked for the float lockout and could not find anything. It has always worked by just pushing it past the detent.

I finally got it to work.
Had to remove the control valve.
The shaft that controls up and down movement protrudes out the back of the control valve. Remove two plugs on the top and bottom of this protrusion and you find a spring and ball assembly under each. As soon as I removed the two plugs I was able to get the lever to move an additional 1/2 inch. Bingo I thought this must be the float position. I noticed that it looked a little dirty in there so I cleaned it up, dropped the balls back in replaced the spring plugs and now I could feel the control snap into float position. Put everything back together and I now have float.
It sure is great ( and unusual) when you can fix something and it only costs you your time and not your time and money.
Thank you guys for all your input. /forums/images/graemlins/grin.gif

This thread has been really useful as I try to puzzle out my "new" used 7305 with 417 loader.

Mine won't go into float mode either. For that matter it doesn't seem to even go into full down mode. Pulling the two screws/springs/balls from the end cap didn't help at all. After a lot of head scratching and measuring, I finally concluded that my endcap isn't drilled deep enough and the plunger is bottoming out on it. I tried backing out the screws attaching the cap and down operation seems much more reasonable. It seems difficult to believe that a 4 year old tractor still has a manufacturing defect preventing the loader for lowering correctly though. Hopefully a trip to the dealers parts department will clarify this.

I also had a problem where the bucket curled the opposite direction from what the diagram on the loader said it should. I tried reversing the hoses to curl cylinders and was amazed to find it didn't work. I could curl down real well but couldn't curl up at all. Putting it back it seems to work normally. Maybe the valve has some kind of compensation for the difference in plunger area due to the rod on one side?

I am wondering if my diagram is just wrong as it shows reversed bucket curl compared with the photo posted earlier on this thread. My diagram also doesn't show a float position even though I do have the end cap with the detents for float.

I couldn't escape work long enough to hit up the dealers parts department so I decided to drill the end cap and worry about a new one if I screwed it up. When I started to drill, all I got was rust dust. I turns out that the hole wasn't deep enough because the shaft with the detent had a groove worn in it, probably due to a lack of lubrication, and the loose material had packed up solid.
