Mine had 4.17:1 rears under it, and it would do 60-62 easily. 65 was possible, but it was turning pretty high by then. Didn't really want to wind it much beyond there. It had 11.00-22.5 tires. Taller tires would have made it move along a little faster. On the build sheet, the original purchaser had asked for 60 MPH. So, they gave him a little extra. Yep, you've got yourself a real good one there! Enjoy!

You can see it's getting a little light on the steers. Wow! You'd never know from looking at that chassis that it was that heavy.

I drove an early R700 a little bit. Had the V-8 Maxidyne with the 6-speed Extended Range Maxitorque transmission. It was the early cab, like that one. About a '70-71...had the darker green interior. That thing was a beast. But, the Maxitorque took some getting used to, since I was used to the 18-speed. I kept wanting to shift too quickly! The view over that longer nose was really something. Felt like there was a mobile home sticking out the front of the cab! That one does LOOK like a western model. Maybe can find out more as you go. Looks like a great find. Love the flat-back, all-steel, green-on-the-inside cabs. Look forward to seeing more on this one.

So, you're saying she had really questionable taste...right? LOL! Just kidding, Bob!

Well! Happy Birthday, Fuzzy Draggin Buzzard Wagon!

Yes, then you have a direct drive trans. The "0" at the end would have made it an overdrive model, and it would be called a 9-speed (hi-4th and lo-5th would have been basically the same gear). With the direct 10-speed, you can split each gear in the main using the compound. On the 9-speed model, you could split the first 4 and only (typically) use hi-5th. Depending on the axle ratio, you should be good for 60mph or so. If you do have the 673C, that is (IMHO) one of the best versions of the Thermodyne. I had that in the '70 I had, and I drove one (too) many years ago to pull a lowboy trailer. Seems like it was a '66 or '67. Had the 18-speed Quadruplex. Was a tough, tough motor. Of course, it was nothing compared to the HP of the later ones. But, it was a good, reliable piece. The one I drove back then had the air filter retrofitted to use a paper element inside the original oil-bath housing. When I had my other one a few years back, I tried to find one of those conversion kits, but had no luck at all. I think Donaldson has a complete unit that will work, though, if you're interested. Got to admit to being more than a little jealous! That truck has great potential.

Every time I see pictures of these when they were new I want to cry! What I wouldn't give to have one of these "new old stock" trucks. There's a picture in one of my books of a pair of single-axle R600s...one with the Thermodyne and one with the Maxidyne. If I had the two in that picture, I would be set! I keep watching for one of the old CA36 cabs to show up. If I ever find a solid one, it'd be worth finding a truck just to put it on. Can you imagine finding one of those cabs in a warehouse somewhere? What would it bring at auction?

Earth to Matt...Come in Matt! He'll know for sure.

Since you mentioned the R607!

Sounds a lot like that angle bracket you mentioned above, doesn't it?

Here is a '65 tandem-axle clip...

...or maybe the R609 tandems came with the 711 and the singles with the 707 (both 707 cu in). All I remember for sure is the R609 was NA and the R611 was turbocharged.

R611 definitely designates the engine. The "standard" transmission, at least for certain year models, was the TRD-722, 10-speed direct Duplex. Of course, many other transmission options were available, such as Triplex, Quadruplex, or even RoadRanger models. None of those would change the "R611" model number, though. That indicates the engine was some variant of the ENDT-673. Depending on the exact year, that could be the 211HP "673" or the 250HP "673C". I think there were other versions of that engine as well, all still being an "R611" model. By contrast, the "R609" had the END-707 or END-711 (depending on the year), normally-aspirated engine, but was otherwise the same exact truck. Here is a 1965 brochure clip for reference.

Sounds like a Duplex. 2 sticks? Got picture of shift plate? Could be 9-speed (overdrive) or 10-speed (direct). Very common behind a 673T. On the gearcase at the front of the engine, you should see numbers like "T673" or some variation (see below). Those numbers can help identify the specific variant of the engine. This one says "T673C", indicating the 250HP version, the ENDT-673C. Also, there could be a tag on the engine that shows the actual HP rating. On the pump, maybe? Can't remember. R611T...The "611" indicates that it came with a ENDT-673 Thermodyne of some version. The "T", if you didn't already know, indicates that it was a single-screw Tractor. "ST" would have been the tandem-axle version. We need more pictures! We love pictures!

Another year older and deeper in debt, Huh Jo-Jo?!

The tag is the finishing touch...

Rats...sharp tails...

Have seen guys change the front tires right on the truck with a bar. Not even remove the rim from the spindle. Spindle makes a pretty good pivot. Seen the starting fluid thing done many times. Not something the OSHA folks would approve of!

I can't wait to see the next episode of "As the Fuel Pump Turns". LOL!

Ever figure out anything on this???

Checking birthdays every day if I can remember to. Lots of folks who have not been on here in YEARS. Weird thing is how many have a "joined" date and a "last visit" date that are the same. Seems odd to take the time to join and then NEVER come back. Like I said...weird.

I like what you have there. Love the old steel-dash trucks.

Rats...they got sharp tails.

I like that killer attack dog guarding you there.

Maybe! But, then again... LOL! R models do look a little "narrow in the tire". Always have. The ones with wider fronts do fill up the fenders better. Purely an aesthetic thing, for sure. Just to keep you miserable, look for an Accuride 32052225 or equivalent. That's a 22.5" X 9.00" W/5.00" Offset "Heavy Load Application" demountable rim (code for "Dayton").
