We got the boom pin out and the boom removed.


I was able to line it up and pull the pin out with the mini excavator, no sledge hammer required.


The paint shop called while I was doing that, and I picked up the freshly painted hood and got it back on the dump truck.
Boom off, hood on :D

WTF is that company gonna do when you finally quit/retire? You've posted pics of what their equipment and rolling stock looked like before you got there...

I don't think they will be far behind me. None of the current batch of kids are interested, and the current bunch are not much younger than me.

I torched and hammered the bushings out of the end of the boom and it didn't look too sweet but the Pape machinery field mechanic came by and took a look at it he said he'd keep those bores.

He's going to line bore the house where the boom attaches and also the hole in the middle of the boom where the boom cylinders attach and they're going to manufacture a new pin for me.

We're going to go with heating up the lower boom cylinder pin bosses on the house and see if we can shrink them with a torch a little bit.

There's a whole lot of labor to line bore those two holes so we're going to skip it and see what we can do elsewhere.

The boom end has a spacer in it, floating in pounds of old grease. I had quite the dumpster fire going getting the first bushing cut, then I could pound that one out and scoop out the old gunk.





I pulled the tool box off for access to the upper bore and cleaned up the grease.


The machinist will get those bores welded up, then start the machining process and press in the new bushings in the boom for me, rather than twiddle his thumbs. We will get as much as we can done, but it will go into a second day.

Gawd...y'know...I just don't miss that shit...not one tiny bit.

I really need to get back to my home planet before my transportation breaks down entirely! This morning I awoke to am alarm warning me that my spore drive regulator was over heating. I was in the process of tearing apart the regulator when I noticed that the obulucation chamber was cracked thus causing the over heating! So I fired up the dylithium torch and sealed the crack! While putting it back together I ran across another problem - the main fluid for the obulucation chamber was very low! On earth the closest thing to the fluid that I need is diet coke. Thankfully AutoZone also had that so I am now back up and running! Thank You Auto Zone!!

The mobile tech had to grind a little off the fuel tank for clearance.


I cut a few troughs in the bushings with the cutting torch, being careful to not cut clear through. It took all the fight out of them, I could drive them out easily.


The main boom bores all welded up and machined back to a tight 0.005 clearance. This is going to be fun fitting the boom now!!

Yesterday was swapping winter wheels to summer on my 2014 Mazda 3. Today was replacing a starter in a 1999 Toyota Corolla - I believe its anti-spin clutch failed. One more car to swap tires on. Much more like backyard mechanics than major work on construction machines.

I'm not, but I should be installing some drive axles. They're just sitting on my couch, waiting . .. .

We got the boom back in place with the new bushings and pin.


The upper boom cylinder location is built up and line bored to 0.005 clearance on the new pin.
Now it waits for a cylinder overhaul.

When the machinist got that end of the boom picked up with his crane, I gave it a wild ass guess of 2500~3000 pounds. His fancy little service crane has a direct weight readout on the remote control. 2450 pounds, I had a pretty good guess.
The other end with the bucket was resting on the ground so the whole thing was ~5000.
Those pins are 70MM diameter and weigh about 40 pounds, for some perspective.

I am silently watching but as a mechanical engineer in awe. Had few chances to play with big boy's toys and especially since BIL was hired by CAT, never stopped receiving updates about hottest stuff :-D.
