Brocky is correct. This was taken a few years ago at "Brad's Farm" near Maiden, NC. If the date stamp on the picture is correct, it was in 2013. Funny, I didn't think it was that far back, though. "Ain't it funny, how time slips away?" Here are a few more shots from later (2017), with the grandsons (AKA: The Horses) hanging out with it.

That's the sequence we used (most of the time anyway) on the 20-speed (main direct in 5th). On the 18-speed (main direct in 4th), skip Lo-Split 5th and Direct 5th (they duplicated other gears). So, they were the same up through Hi-Split 4th. Then you just shifted the main to 5th. Long-legged mothers, those 18-speeds.

I know there were 2 different R600 hood lengths. Have heard it is 1" different, 1.5" different, and 2" different! Both of these "new" models say 54-1/4" long.

Nice...

Mack trucks and Cat tractors. Takes me back...

New Bus Smell. Been a long time on that one, Bob.

Did you ever figure it out? Bad treadle valve or a stuck pedal hinge?

Good tip on the technique!

The R that I drove most of the time when I was young (and the world was too) was a '67. The interior was about that same color of pale green. Always reminded me of the inside of a school bus. The later ones we had were darker...more of an olive drab color...and more of a flat finish. I think the '70 I had was that darker green...before somebody painted it white. Apparently, the color changed sometime between '67 and '70. Looks like the throttle knob is missing. Sure hope he can find an original one to match the fuel shutoff. They look a lot better than the plastic replacements you see so often. Is that a pyrometer in the center panel? Really like the padded panels at the top of the doors. The paint always got rubbed off right in there. The diamond plate headlight panels are great, too. The look like a factory upgrade! Matching pieces on the door jambs look cool, too. Looks like it could use a long-eared dog! I changed many a filter in that old-style "oil clarifier" canister! I was surprised that I could still get the filter cartridge and the seal for mine when I had it. The check valves on it leaked down, though. Made it kinda tricky to check the oil level! He sure has a nice ride there. I'd like to see a lot more info and pictures for that one. Please pass on my appreciation (or it it jealousy?) to him. Looks like a lot of work/time/money invested. Kudos!

Older RD hood had same cowl shape as R. Newer RD had a square side, more like the Super Dog. Also remember that there were 2 different lengths or R-model hoods.

That red R-model makes me cry! Gorgeous. Steel dash. Quadruplex. Only thing wrong with it is that is isn't sitting in my driveway.

I have this one, too. It's actually pretty informative. Seems like I bought it off the discount table at a book store for $9.95. Of course, that was a loooooong time ago!

I found a brand new one on eBay a few years back. Seem to be several used ones out there, too. Wish I had swapped that new one out for an old one before I sold the truck, though!

Yeah, I wouldn’t use Quaker State either. Lots of folks did. But I took too many apart that were gummed up. I think it was okay if you got it hot regularly. But, around-town-mobiles seemed particularly bad to gum up with it.

A Yenko Nova with a 502...cool. Saw a flathead Ford in there with Offenhauser heads on it. The story of the actual Miller/Offenhauser engines is really cool. Fred miller was a character! Well worth reading sometime. Lots of websites out there with information on them, but the milleroffy.com site is a pretty good place to start.

I did not realize that JOT was an offshoot of ATHS. Very interesting...

If mine had been anywhere near that good, I probably never would have let it go.

Put a harder pull on it and see if it gets any louder! Might not be workin' it hard enough to get enough heat in the exhaust. My 611 didn't make much sound either...bobtailing. The 611 I used to work would get much louder when it was actually pulling.

Ahh. Cool.

Oh, and I once saw these types of wheels called "artillery" wheels. But, I don't know if that was an accurate use of that term.

I was something like 6 years old, and was walking in front of one I thought was empty. No muffler. Full air tank. Blew dust out from under the truck. Damnedest thing I had ever heard! Sounded like the truck was angry at the world! I figure that's what it would sound like if The Almighty took his impact wrench to the earth. But, it's something you never forget, after you heard it once. Before that, I'd never even heard of an air starter. I did, however, already know about pony motor starters on Caterpillar tractors. But, that's another story...

First time I ever heard somebody start a truck with an air starter on it, it scared the ever-loving s#!t out of me!

Car? What car? I don't see any car.

Yip. No point in crying over it on the side of the road!
