Two words: Killdozer. Oops, that's just one word.

Nice LoBoy 'Goat!

You must live in a tough neighborhood, having to chain up your trailer like that.

LOL! It was a friends trailer I borrowed. He usually keeps it at this shop where it can sit unattended for days or weeks at a time. I live in a small mountain community where folks don't even lock their doors! The picture was taken near the center of Denver. I'm impressed you knew it was a LoBoy (but not surprised!)

My dad fully restored a late 1960's JD gasser Backhoe a few years ago he uses around his property. I don't know the model off the top of my head (420 maybe?). He can't seem to buy and fix anything without doing a full blown restoration to it. That's how the LoBoy happened. We started working on it, and the next thing you know we had it split and we were restoring it...sigh.

If the heavier jack, oil and BFH doesn't break it free, you might try taking it for a scrape around the property behind your Kubota to make the pin work in the track and let the PB Blaster penetrate on the moving pin. Oil up both master pins, so you only have to do it once, but making the pin move in rotation may be the best way to loosen it.

ETA: Dragging the dozer around may also permit you to place the Master Pin on the top, or slack side of the track run, which may relieve some of the tension on it. It looks like now, the master pin track chain link may even still be engaged with the sprocket.

Woohoo! Got those )@$#(ing master pins out and the tracks off!

Details and pix here.

Very cool!

63 years of stuck doesn't give up easily.

It's ALIVE! MUWAAAAAHAHAHAHAHAHAHAHAHHA!

Good oil pressure, I can see water circulating in the radiator, no leaks outside of what I spilled filling the fluids.

No power to the coil from the ignition switch, but I need to rewire it anyway, lotta "farmer fixes" (wire nuts and electrical tape...) and the insulation is pretty brittle on most of the wiring.

I'm a happy guy!

"I'm a happy guy!"

As you should be! Good news, keep having fun.

THAT.IS.AWESOME!!!

Unwrapped the wiring harness this morning. YIKES!

^^^Looks like somebody opened a can of worms and dumped 'em on the floor!

... and one day, the 420C will look like this?
(Not at all mine, an image)



Actually, I like this project ... keep posting pics and progress.

@cjevans - Highly unlikely. That feller has more money tied up in paint than I have budgeted for the entire project!

Coupla rattle cans over the worst of the rust, but overall it'll stay in its "working clothes".

... hehe, indeed, working man's clothes.

Weld plates over the really rusty bits?
And a couple of coats of clear to retain every scar, scrape and gouge of history.

... keep the updates coming.

Tin is in remarkably good shape, just some surface rust.

The right track frame, OTOH... Major piece broken off the right side of the front idler mount. I HOPE I can weld it back together and still have enough adjustment.

I can update here occasionally, or save Para the bandwidth and just link to my site.

Or not, I know it's about as off-topic as they come.

Updates please!

Nothing picture-worthy. Finished up rewiring it yesterday, started it again and checked out the hydraulics.

They work, but EVERYTHING leaks and the fluid looks like chocolate milk. Add to ToDo List:

1. Drain, flush and replace fluid

2. Clean, dope and tighten everything

3. Overhaul the cylinders

Should be able to find cylinder kits. Paying for them may be another issue.

Found some more presents when I drained the transmission.



Right side final drive off, wasn't too difficult. I started on the clutch pack but I have to knock off early today to go help a friend.

Got the transmission out today. Took a crew of three (Me, Myself and I) about 5 hours. 4 jacks and an engine crane, lot of fussing with jack it up a little here, let it down a little there, move it back a little, reset, up/down/move/rinse/repeat. Biggest trick is getting the front flange of the transmission case up and over the rear crossmember for the undercarriage without tweaking the propeller shaft.



It's a LONG walk from the front of the transmission to the clutch and throwout bearing. I suspect putting it back in is gonna be a cast iron bitch. Definitely going to have to fab up a jig to hold the trans and allow me to tilt it just right while rolling it into place. Have some ideas on that subject, plenty of time to think it over.
