Re: Update pic- The Fix is in...Engineering Help needed. Kubota RPR kit -No details.

OK, the 4590 is all done. It took awhile to get this thing done.... Below are some pics of the dipper boom assy and weld up.
I also had to repair the boom swing Cyl which leaked. Then elected to just do the curl, dipper, and stablizer seals too. So, done, runs like new(ish), and... greased top to bottom. what a fun mess that is getting all the old dirt-cake grease-mortar out..(my own fault).


Pics of the dipper/boom repair fab-up. Welded in the new pin Boss to the dipper, then placed the larger support ring and welded inside and outside to dipper. Some grinding clean up to meet the 3.85" OD max space in the boom receiver. Pinned and greased... solid as a rock. No more beating anything latterly beyond a nudge!

Looks great, I hope you painted the whole backhoe while you had it apart!!:D

I don't think these were Arens built backhoes, maybe Ameriquip or Arps?

Ok now, can someone get the photos into the post so they are available if the google links fail in the future? :)

Would have loved too. What’s the trick these days? Pic size upload total was so limited or is that a result of my rank? Tried putting into word doc and converting to pdf even. Still maxed above limit. (Way). I’m sure it’s listed on the sticky’s but I’m just so dang busy. Toss in via URL link was all I had time. Sorry all. Gimme a solution and I’ll get er’ done. ***129299;

Contemplating which avenue to take on one of my loaders that has sloppy pivots. Kubota don't offer a bushing kit for them at all so it's probably line bore and bush but I do have options. I can bush with 660 CA bronze inserts or go all out and bush with Thompson caged roller bearings with new pins of course.
