JD 120 general rebuild thread, bushings, pins, CWS thumb wedge QC bushings, hoses

There was another chapter to this story that I left out.
The line boring field machinist started a fire with the welder that followed up the hose around the pilot lines up into the right console. I had been around and asked if I could help and he said no, he had it. In retrospect I would have been helpful for fire watch!!
He put it out, and then decided to start the machine without doing much investigation. I suspect that killed the computer because it was dead. No throttle.
The next day he set up line boring and spliced the harness and no joy.
They sent out a proper tech who fixed the harness, and figured out the computer was no longer talking. A couple of weeks of looking around for a computer came next. I found one on Ebay and hinted strongly that they get it coming.
Remember, I'm doing this rotec and all this with the hope that they come through for me, as I have a month long job to start.
Yesterday I call them and the computer is out for delivery, and the person says " we will have a technician up there to install it Tuesday"
Gentlemen, I lost it. I said I had been most accommodating and kept the owner out of this, and the lawyer. I said I am mobilizing this machine to a job 50 miles further away and they had best make that fix happen TODAY!!
The squeaky wheel got the grease. I have a throttle in and trained up, and there is one more burnt piece of console coming. I told them I do not need them to come install that, just drop ship it to me.
They came through for me. I am grateful. Somebody else out there got put off and I am sorry for that, but do try to use enough welding blankets and due diligence when welding on a machine. I know I learned that one.

sun gears are back in, finals assembled and topped off with gear oil, hydraulics topped up, swing bay filled with 14 tubes of grease to start. Tool box is back on and all the covers and loaded up on the trailer to go to work. I was mistaken in saying the throttle was properly trained, i discovered that it was about 65% today so I got the procedures from the tech and did it right. Now i have full throttle authority.

I dug trench with it today and it was nice. Much tighter now.

Very cool to see someone invest time and money in an old machine they like. Everything now is run it hard throw it to auction and get a new one. Or lease it

I put 15K in parts and outside labor and put off a big purchase. There's no point in getting new iron when they don't use it enough to justify it.

And that was less expensive than renting a machine of that size for the time that you do use. A rental on a site that isn't being utilized every minute is throwing away money.

Apparently I had fumble fingered and archived the missing photos of the machine when it was really split in two.
The dainty little sun gears:


With those out, the mini ex dragged the carbody out with ease.


I blocked directly over the idler with the cutoffs of apitong from the trailer deck job last year. Those are some heavy stout chunks of wood.
This is the point I got to before John showed up and made it all go together easily

I think you had it all figured out really well. I was just another pair of eyes and a torque wrench.

Skyking1, thanks for putting all the info/pics/vids up- that was a GREAT read/accomplishment- especially the added details of how/why you did certain steps the way you did…and then to see the house balanced away from the undercarriage…just awesome! Also a bit jealous of your metal/fab work too…very cool to see people make difficult jobs look easy. Well done!!!

Thanks. I've got the bucket end of the pins to do, and my travel alarm cancel button doesn't work. I don't remember when it last worked lol. I'll have to get some wiring schematics and dig into that.

A little truck for marking all of your hoses so you know where they go back is to engrave your caps/plugs. I have all of mine numbered and initialed. Hose with plug #16 goes on fitting with cap #16. Certain sizes I have 50 cap/plug pairs.
