Good evening all,
Picked up a Kubota KX161 for the farm, had it a little over a year now. Bigger than I thought I wanted but I’m so glad I went for it, great size machine for chores.
Had the intentions of going through the lower end of the dipper arm as a winter project. Had some slop in it (06’ model with 4,300 hrs). Got sidetracked when the top seal went out of the swivel joint. Got it out and 34 o-rings later, she’s back in and leak free. While I have it in the shop, I’ve decided to go ahead and tackle the bushings. Unit has a factory thumb and the factory quick connect to the buckets. Both the bucket and tipping links have some wear, but the most noticeable is the very end of the dipper stick, where the main pin goes through the thumb, quick connect and the arm. This setup uses a dust seal and bushing on each end of the hole, with a collar in the middle. While the collar has the same OD as the bushings, it’s much thinner. Once everything was off, I noticed the bushings were VERY worn but the pin hadn’t worn into the actual bore just yet, there is still bushing material left. The dust seals are pretty much gone, some metal left. A very faint amount of the grease groove is left in the bushings. The bushings basically wore down to the collar, so everything is smooth in the bore, no ridges. Because of this, there is hardly any lip to even attempt to get a punch or anything else in there on.
Any suggestions on how to handle this? I’m not a welder, but have plenty of family and friends who are. Read some other stuff online about welding a bead across the bushing, letting it cool and then driving it out. May have to build something up just to have something to hit on. If it comes to that, it shouldn’t be a problem to get someone over here with an arc or a mig.
I’m attaching some pics and have included a pic of the new OEM bushings. Uploading from my iPad so it only let’s me do one pic per post, sorry!
