300U Sloppy Hydraulic Lever Fix ?

On my 300 Utility, the lever for the fast hitch valve stripped, I have a few extra levers with fair looking splines, but when installed on the
valve there is a large amount of slop between the the lever and the valve shaft, the shaft must have a good amount of wear as well. I would like
to avoid spending $90.00 for a new shaft, and $150.00 or more for a lever, my money tree has lost all it's leaf's for awhile. Was wondering if
Anyone has any Ideas for a fix on this without spending too much. Thought about "pecker welding" on the shaft or the splines of the lever but with
as much use as the lever gets, it probably wouldn't last too long. Maybe tacking with a wire welder or some JB weld ?? What would You Guys Do??
Thanks...Tom
 
I would drill and tap the handle for #6-32 set screws through the aluminum and through the steel insert so they are at 90 degrees from each other into the splines. Then with everything clean (spray brake clean clean) I would assemble it , tighten cup point set screws to remove the slack. Then I would apply Locktite shaft and bearing mount to the more open side where the setscrews were opening the slack in the splines. Let it cure and put on the outside plate. Jim
 
I think the lever is made of Aluminum, but there is an insert with the splines that looks like steel, It's Magnetic.

That sounds like an excellent Idea Jim. My only concern would be using my less than precision Harbor freight bench drill press to get straight into the narrow lever, I suppose if I take it slow I'll be OK. Thanks for your Awesome Idea!!...Tom
 
Before I would take a chance of wrecking a good handle I would try to make the shaft larger. I would take a soda can and cut a piece and wrap it around the shaft and push the leaver on. The thin alumimum should conform to the splines and make it tight. If that don't work then you can go to plan B. and you won't be out any money just time.

Thank You bob for You're suggestion, that's a probable Idea if the lever would fit over the aluminum. I'm going to have the valves off the tractor soon to replace o rings and deal with the sloppy lever issue. Once I get the parts on the bench I'll be able to see what needs to be done, Thanks for the reply...Tom
 
That is an excellent suggestion Jim. I have had a couple come through my shop that had been repaired that way some time previously, and were still holding well and tight. One a different one, we had a local machine shop cut 3 handle blanks from steel with the splines in it with an EDM, and it worked very slick for. We had to heat and bend the shank of the new handles to match the old ones, then welded a ball on the end of each one. Cost was a very reasonable $75 to have the 3 splined handle blanks cut.

It was steel on steel, soda can is virgin pure aluminum, soft as a white bread sandwich. I have fixed it using the setscrews. The lever can move side to side on the splines and that causes the wear. It would be far less with screws, than with an aluminum insert. Jim
 
Right but you really need a milling machine to accurately drill holes for set screws. It's pretty easy to muck it up with a regular drill press no matter how careful you are. BTDT. Spend hours setting it up straight using squares and measuring, measuring, measuring, pull the trigger, and the hole comes out diagonally through the side of the part nowhere near where you need it to be.
