Popular Post Robo987 Posted April 25, 2023 Popular Post Share Posted April 25, 2023 I acquired this Mack last year in 2022 and finally got to go for a little drive last weekend. It was short and didn’t get to go real fast but damn did me and my 11yr old have fun. Can’t wait to get her out on the road and take her for a real test drive. I remember going to work with my dad and riding around in big trucks when I was a kid and to own a truck and have a kid that loves this stuff as much as I do is such an awesome experience. 8 3 Quote Link to comment Share on other sites More sharing options...

Thanks for picture. hope more pictures in future;; interior/ engine compartment. So it does have the 673t but I’m sure what the road ranger is. The transmission is a Mack 10 speed and I believe the model of the transmission is a TRD(L) 722(0). I’ll definitely be posting more pics in the future as I get around to cleaning it up and fixing things. 1 Quote Link to comment Share on other sites More sharing options...

Popular Post doubleclutchinweasel Posted April 27, 2023 Popular Post Share Posted April 27, 2023 1 hour ago, Robo987 said: 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! 2 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines." Link to comment Share on other sites More sharing options...
mechohaulic Posted April 27, 2023 Share Posted April 27, 2023 twin stick duplex would also be a R611 designation . set up a new '69 R611T for customer while at Mack ;it was a 13 speed road ranger. simple vins (and times) then . 1 Quote Link to comment Share on other sites More sharing options...
Popular Post doubleclutchinweasel Posted April 27, 2023 Popular Post Share Posted April 27, 2023 (edited) 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.

doubleclutchinweasel Posted April 27, 2023 Share Posted April 27, 2023 (edited) ...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. Edited April 27, 2023 by doubleclutchinweasel 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

mechohaulic Posted April 27, 2023 Share Posted April 27, 2023 can almost have a sick stomach looking at those brochures. when Mack was bought out by another branch a janitor had a large ; (large to point couldn't pick it up had to drag on ground) almost full of the truck brochures. I picked out quite a few=not enough . rest thrown away. $10-20 on ebay today. who would have known. 2 Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted April 27, 2023 Share Posted April 27, 2023 same company that bought the R611T with RR also has the first R607T 1001 today. the 611 long gone but ole Number one R still there. R611 was replaced by Mack twin-screw ; don't remember transmission .wasn't 5speed possibly 12 speed. that was replaced by superliner. i see off topic happening ;; sorry.
