I changed the bushings on the boom arm were it hooks on at the bottom
next to the swing arms.
Got new bushings and to my surprise they are a SPLIT Bushing.
But when I put them in they pushed right in by hand. This I said will never do, so I made my own bushings and a new pin and I found I had to go a little over size for the Bushing OD and, the pin I made to fit back to orginal size. If I have to replace the Boom to dipper arm some day I'll make my own. Although I did take the side to side play out of the Boom to Dipper Arm by putting in a spacer about a 75 thousand thick shim washer. Made a big different in movement. You can get Ram Bushings for the hydralic Rams as the Dealer had ordered me the wrong ones once, so I know there available.
Anyway I 'm a lot like you guys out there in the field if I could fix the Float problem without without breaking the bank I would fix it.. Sounds like it could end up mushrooming into a major fix. Never use it enough to worry about.
