Howdy, Larry! It varied from year to year here’s a 211hp ENDT-673.
-
My genuine pleasure, gentlemen!
-
A good hair dryer definitely helps.
-
That would be a wise investment, right there!
-
Hard to do. The engine almost disappears between the frame rails!

JoJo, the ones on my FA535 axle did not require anything done to the holes or the bushings. Not sure if that has always been the case. I can't remember for sure, but I think mine had a needle bearing on top and a bushing on the bottom. Seems like freighttrain did a set in about 4 hours! Mine took me all day!

Starter motor on ENDT-676

I can't make out all the words, but the stuff in the red oval is all aluminum on the "L" suffix trucks.

Oh, and sometimes cabs and hoods get swapped. The VIN number on the frame might tell a different story. Might really be a 686, for instance. -

"RS" prefix should be a Western version of the "R" with a steel frame. "RL" prefix would have been a Western "R" with an aluminum frame. "L" suffix is for lightweight components (check for an aluminum bell housing, for instance). "S" suffix is tandem drive. R685 and R686 would have different engines. Not sure what the HP ratings would be for 1979, but originally (like in 1967) the R685 was the ENDT-675 237HP Maxidyne. R686 was a larger engine (ENDT-676 285-300 maybe?). And, again, the Western versions may have been different on engine specs...I don't know for sure. Most of my knowledge on these things stops in about 1973! -
Kinda neat, too.

This particular (1965) one is a good reference, because it shows the "standard" configurations of 2 different R600 models, and it has the second page which shows options. You can see the optional engines, transmissions, and clutches...among other things...on the 2nd page. For instance, it shows the ENDT-673C engine option for the R611. Wish I had a bunch of these in person!

Mack called single-screw models "4 wheel" and twin-screw models "6 wheel". You can see examples of that on the brochures I posted. Most of those 673's had a HP rating on a tag somewhere on the engine. Can't remember if it is on the engine or the pump, though. I'm betting 211 HP, as I think that was the rating on the ones with no other letters after the engine model number.

This has to be one of my favorites! The newer galvanized cab.
-
How about a few components?
-
Not sure of the year, but here an R615. I wish some of these had been bigger and better.
-
Here is a 1980 brochure on the revised (CA49) cab from a few years back.
-
First one from '77 and the second from '78...
-
None from '75, but a few from '76...
-
A handful from '74...
-
A couple from 1973... The new cab showed up here.
-
How about some 1972's?
-
Only 1 from 1971...
-
A few from 1970... The blue R700 ones show a lot of different engine options and the model numbers associated with each one.
-
A couple from 1969...
