Split shims for on-shaft spacing?

Post by AddamsonFlint » Sat Jun 08, 2019 9:21 pm

Got a fair amount of play in one of the cylinder points on my JD 9300 backhoe. It would be great to be able to shim it without having to take that whole thing apart. I'm sure I'm not the first to have this want, so I have got to think that it is already "a thing" and that there is some sort of piece available to shim without fully pulling the pin. Thoughts or input?

(How do I attach a pic to my post??)

Here's a google drive link to what I'm talking about on my crawler:

Good morning,

This may work

I call them split washers, hinged washers, or pivot washers. They come in all shapes and sizes. I have used them on various types of shafts and collars.


These are pretty cool too, but a bit robust for your application

If you just want to reduce side to side play get some steel machinery bushing washers of the right size. Put equal amounts on both sides of the cylinder. You will find these on display at a lot of hardware and farm stores, Fastenal, etc., in different thicknesses and diameters so you need to measure and figure out what you need.

It is not a big job, just position the hoe to get the weight off the pin. Wedge/block under the cylinder end to keep it from dropping. Remove the pin keeper. Tap the pin out of the boom ear and get the pin end just into the cylinder boss. Install the washer(s)on that side and tap the pin back into place. Repeat on the other side, then re-install the pin keeper.
