Cool. I'll just match it up when I yank it out.And, yes, I do tend to over-think stuff. But, when you see all the people out there who don't think at all, I figure I should do my part to raise the average thought level! LOL!

Yep. You got it!

Oh, it was the old filter cartridge, before spin-ons. The B-model used a similar one, but it sat lower. This guy had one like on mine (see image), which sat a LOT higher. Not an issue under an R hood, but kinda "unique" on a B! I'll see if I can find that old thread. Not even sure what site it was on...

Strange that NOBODY on here has put a water pump on an ENDT-673-C! Or, has anybody else actually GOT a 673-C? I'd be tickled to death if somebody would read me the casting number off the front of a water pump on a 673-C! P.S.: I still believe mine may be wrong.

Yeah, some guy had a B-model with an R-model engine dropped into it. The factory R-model filter canister stuck up through the hood! Had a nice, trimmed hole in the hood for the filter to stick out of. The more I trace the possible part numbers on mine, the more convinced I am that somebody MAY have swapped in the "wrong" pump at some time in the past. I can't prove it right now, but at one time, I THOUGHT the belts looked just a hair out of alignment. But, since somebody had already built a pretty nice bracket, and swapped in a regular alternator, I attributed the POSSIBLE mis-alignment to that. Now, I'm thinking it may be due to a water pump change. I'll check the alignment with a straight edage, and see if I can make heads or tails out of it. If the alignment needs to be shifted a fuzz to better line up with the crank pulley...well then, there you are! Either way, it looks like a body has several pump configurations to work with! And, if it all gets too complicated, I can just let you have it!!! Right?

Oh! You funny, 'Train! That's mighty nice of you to offer. Not just everybody would do that for you! 'Course, you'd either have to swap the oil filter or cut a hole in the hood of that B. Remember that post on here a few years ago?

Looks like you wound up in the same place I did! I'm sitting here looking at those same pictures! I spoke to the Mack guys in Knoxville this morning. They couldn't pull anything up, even with the engine assembly number. So, the parts guy called an old guy higher up in the Mack organization. That individual told him it basically came down to "short shaft" or "long shaft", which (supposedly) equates to a 2-groove or 3-groove pulley. So, when it needs work, I'll just pull it off and match up the shaft length and casting height with the drawings. In the meantime, I think I'll check the alignment of the water pump pulley to the crank pulley, to be sure they actually line up. Because, who's to say this is the original (or even correct) pump on there now! If all my info is correct, the "360GB334" casting is 3.6" tall (from machined surface to machined surface), and the "360GB443" casting is 4.0" tall (according to BEPCO information). And, the "short shaft" protrudes about .94", while the "long shaft" protrudes about 1.5" (according to Haldex-Midland info). Then, there are variations in impeller (cast or stamped, flush or protruding). All this sound about right to you???

Maybe one of you old parts gurus can help me identify the water pump on my '70 R611ST with the ENDT-673-C engine. No problem yet. Just trying to identify parts. Water pump casting number - 360 GB 443. Build sheet number - 316 GCA 492 P37...as near as I can tell. Not sure about shaft length, as it is still installed & running. Any idea what the part number may have been superceded by? 316GC1184? 316GC1210A? 316GC1211A? 316GC1211B? I would assume that a pump with the same casting number, the same shaft length, and the same impeller configuration would interchange & function correctly? Thanks, y'all!

Give it time, Jeff. Give it time!

Yep. Sand-cast prototype. Probably worth whatever anybody is willing to pay for it. Wow!

Was that the END-864?

EXACTLY! That's where I picked up the technique!

Yep. Pull the pedal up. Lots of views, but few answers. You guys are "special"! Incidentally, if you just STARTED a D.D. next to it, wouldn't the smoke be enough to choke it out?

I didn't look to see what the bid history is, but SOMEBODY may have had their "0" key stick. Like...maybe the bidder???

Okay, Here's one the old-timers will remember, but the newer guys may not have seen. When I was young (and the world was too), one of the local guys bought a new cabover Peterbilt, with a Caterpillar engine in it. Some of us guys went over to check it out, with full permission of the owner. One of them started it up, just to hear the sound of a new Cat. Beautiful music, to be sure. And, a gorgeous, brand-hammer new truck. When he was ready to turn it off, he could not figure out how to do so. Turning the key off wouldn't do it. And, there was no shut-off on the dash, like a Mack had. The owner could be seen across the road in the cafe, laughing his ass off at a bunch of goobers trying to kill that big Cat! Even though I was the youngest of the crowd, I had run Caterpillar off-road equipment, and was the only one who came up with an idea of how it might work. Turns out it did! Made me look really cool to the other guys! Anybody remember how? P.S.: No prize money for knowing the answer...just the realization that you're at least as old as I am!!!

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....
