I never learn...

Yep, it's always good to get a long neglected piece of equipment started again.

Any idea who make the dozer blade system? It looks kind of like a homemade system, but might be some kind if aftermarket manufactured unit.
Doesn't look like anything Bucyrus-Erie made back then though.

Good work, guy.

I think it's the original JD-supplied unit. There's a tag on it, I'll check and get back to you.

So that's a gas motor! I thought diesels were common back then but, I guess not. Any idea what the hp of that little mill is? Congratulations!

Can't find specifics in the manual, but I'm told it's 28 horsepower. 113 c.i.

 

[BAP]

It’s rated for 28.7hp at the belt and 23.7hp at the drawbar. I am pretty sure that John Deere made the bulldozer blade for them and it was an option.

When I was younger & had more time, I often was selected to fabricate replacement parts for restoration of old equipment- metal working machinery, cars, locomotives, aircraft, tractors, slot machines, pinball machines, clocks, and maybe my favorite, a WWII Army Jeep, completely original. (paint, lettering seats, pioneering tools, tires, 30 carbine rack, tool kit, blackout light shields, with 13 miles on the odometer, and it ran!)
I love the fact you're bringing the old girl back to life, and hope you keep us informed. Great read so far!

Unwrapped about a pound of electrical tape this morning. YIKES!

Tag on the dozer frame says it's a John Deere Model 62.

Now you know what wore out the treads.

Okay, I just never saw one like that before.

Some people shouldn't be allowed to touch anything mechanical, or call themselves mechanics.

Ain't that the truth? I have used "field expedient" fixes to get through the day, but I fix it right when it gets back to the shed!

No kidding. A fix like that should require a pound and a half of electrical tape minimum.

That's the difference between a true mechanic and a hack.

Got the wiring all replaced, added one of them new-fangled "fuse" thingamabobs, cranked it up and checked out the hydraulics, which I forgot to do last time I had it started.

After figuring out the valve setup it raises and lowers the blade frame, but EVERYTHING leaks and the fluid looks like chocolate milk. Add to my list: Remove, clean, dope and tighten all connections, drain and replace fluid, rebuild cylinders.

Doesn't appear to be charging (6.3v on the battery with it running) so I suspect the generator or regulator need some love. Regulator looked pretty new compared to the rest of the machine, but that doesn't mean much.

If it's been setting a long time, the generator may need to be polarized again.

According to Tractor Data the JD 420C is a 6 volt, positive ground tractor.

Could very well be, it sat for 13 years. When I get that far down my list, I'll try that.

Correct. I'd assume charging voltage would be something in the 7-8 volt range.

Skeets says you are gonna put Kragar mags and wide tires back on that thing instead of the treads. Any truth to that rumor?

Ah...NO! Not gonna Foose it up

Found some more presents when I drained the transmission.

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