Blame Volvo?I guess not...

A few more pics from one book. Old-style dashes (up to '72-ish) in the r/w/b scheme. Isn't that a red/white/blue M-model (again) in the background???

I had thought it coincided with the 70th anniversary...1970. But, I wasn't exactly sure. From what everyone has said, sounds pretty close. I know for a fact I have seen pictures of steel dash R's in that paint scheme.

Are we giving away age clues here?

Didn't the "bicentennial" colors actually appear in 1970 as the "70th anniversary" colors???

Thanks, 'Dog! I thought I was on target on the older stuff. It's the newer stuff I don't know st about!

Yep. Here it is. Looked all over the house before I realized I was sittin' on it! Sorry for the less-than-perfect pictures. But, I think you can see them okay. These are from a book called "Mack, Driven for a Century".

The gold dog was an indication of a Maxidyne engine...which was also painted gold. See the connection? The late 60s - early 70s R611ST I drove in my youth had an ENDT-673C Mack engine, a TRQ-7220 (or 7210?) Mack transmission, Mack axles, a Mack camel back suspension...and a chrome dog (on hood and doors). That truck was as "all-Mack" as it could get, and had nothing gold on it anywhere. There were dozens of copies of this same truck around home...all Mack, all chrome. We had another early 70s tractor on the lot...an R685ST...which was the exact same axles, springs, and everything, but which had a gold dog (on hood and doors). This one had the ENDT-675 Maxidyne with the 6-speed Maxitorque transmission. First time I ever saw a gold dog. Saw several afterwards...all with Maxidynes in them. The '70 R611ST I have now has the same ENDT-673C Mack engine, a factory RTF-915 Eaton-Fuller Roadranger transmission, Mack axles, a Mack inverted camel back suspension...and a chrome dog (on doors...the hood ornament is new). I couldn't tell you if the dog color changed in meaning somewhere down the road...or at what point the gold dog disappeared. But, in the "good old days", the gold dog simply meant Maxidyne...that's all. I think I have a book around here somewhere that mentions it as well. I'll see if i can find it. Thus sayeth The Weasel...

Hmmm....

"Drill" "Extra Hole" Keep it clean, 57!!!

Thanks, 57. I really just need the tach...and a cable. All my other gages are pretty good.

Would this be the double check valve which feeds the trailer brakes? It is supposed to port air to the trailer brakes, regardless of whether you operate the foot valve or the trolley valve, but prevent air going to the tractor brakes if you operate the trolley valve.On my R, it is attached to the treadle valve and incorporates the stop light switch.

Oh! I completely forgot the B-model flatbed in Police Academy!

My treadle pivot pin has frozen to the aluminum frame, and is pivoting on the pedal. Works fine, but can't take it apart to get to the last nut holding the treadle valve onto it. When I replace the valve, I plan to just replace the pedal assembly, too. Sort of get it all while I'm in there. You know? I have looked a a gozillion pedals, but am not 100% sure what the original pedal angle is on the R600. The pedal I can get most easily here is the Haldex-Midland. Their SN-4017A is a 45° pedal. The old Bendix catalogs list a whole slew of pedal angles...up to 56° or so. I can only estimatecthe angle of the old pedal, as the floor is no longer flat & the pedal bumper is well worn. Even the pedal shown at Watts R-model store LOOKS like the H-M aluminum one. Anybody here actually gone through this already? What pedal assembly did you use? I like the look of the old perforated steel pedal, but don't know if I can find one. Any shared experiences and advice would be appreciated.

The gold dog in those days meant the truck had a Maxidyne engine. A chrome dog meant either a Thermodyne or a non-Mack engine, like a Cummins. Somewhere along the line, Maxidynes became "EM" and Thermodynes became "E".I drove a couple of earlier R-models with the 6-speed 2-stick trans. The 107 was direct in high. The 1070 was overdrive in high. Nicest thing about that box was that you had 5 reverse gears. Super nice when trying to back up out of a muddy spot! After growing up on Quadruplexes, it took some getting used to! There was one of these for sale in Charlotte a while back. Had a Cummins & an 18-speed Fuller. A Ford-Hendrickson air ride rear frame was grafted on just behind the cab. Does that make it a McFord?

Red U or DM in the background. Good eye, Vinny.

An L-cabbed B is a nice find. Saw one at Knoxville show last year on a Pete chassis. Most folks didn't realize what it was. He even widened the front fenders to cover the wider-track of the Pete front tires.

Well, that could definitely be something worth looking into! Let us know how that works out for you.

Did you just say "good" & "steering wheel" in the same sentence? LMAO!

Only thing that confuses me (well...not the ONLY thing!) is he says it only does it with a trailer...any trailer...attached. if not for that, it would pretty much have to be a QR valve.

Colors don't matter at all...just as long as you keep that PATTERN! Love that style. I'd do yellow with black fenders. But, I tell everybody that!

This is THE standard R-model dash from the 1st generation trucks. Nothing unusual about it. Looks exactly like my 70. I'd sure like to have a complete gauge console like this as a spare. Anybody got one with good gauges in it?

Find anything yet?

Yeah! Exactly what he said!
