Maybe this Euclid number? https://www.comoros.ubuy.com/com/product/5AX3FXRT6-new-listing-301sq32b-king-pin-set-e4465b-euclid-mack

They did sometimes develop leaks.

Here's you a little something...

That does look to be a double-reduction axle. You can see the caps for the cross-shaft in the lower picture he sent (see below). I have never heard of any issues with these. They are, as mentioned above, not that much different from the standard Mack tandem axle, just rotated 90°. Power Divider makes no sense whatsoever in a single axle, UNLESS they put in something similar to the inter-axle Power Divider as a limited slip unit? Instead of biasing power to the front or rear axle, it would do so to the LH or RH axle? Just guessing on that, though. Basically would be like a gear type limited slip unit. Maybe somebody smarter than me can shed some light on that. Incidentally, I have seen both these "front loaded" and "top loaded" Mack axles in single-screw applications. I saw a LOT more of these "front loaded" units in B models than in R models. I say keep it! And paint the "Mack" script in a contrasting color so everybody can see it!

I gotta agree with mechohaulic. That brown molded steering wheel is the biggest clue to this thing. It is highly unlikely that the steering wheel was NOT factory. So, with a factory brown wheel, I would not be surprised to find the factory painted the interior brown as well. And, like h67st said, Mack would do just about anything you wanted back then. I'd say this has a decent chance of being a genuine factory brown interior, making it the only one I have ever seen. Like the others, I have seen red interiors with molded red steering wheels on fire units. I'll bet there are a few more rare ones out there, but I have no idea how to ever find out what/who/where. It will be interesting to see the build sheet, because they might have some record of it on there. Normally, the original exterior paint color is on there. It would seem logical to put any "special" interior (or frame) colors on it as well. Can't wait to see where this goes!

Did you ever find any pictures that matched that truck? One of the guys over at Just Old Trucks had some interesting pictures he posted recently. maybe you could look through the Mack thread there and see if you see anything that rings a bell. http://forums.justoldtrucks.com/1008/Mack-photos-A-Tribute-to-the-Bulldog?PageIndex=116

This thread is almost as old as that truck!

Henry Fonda as "Elegant John" in "The Great Smokey Roadblock" (1977). Called his truck "Eleanor". Some pretty big names in it.

This was at the show a few years back.

Nothing like that in our local Sam's...

Brad's show was pretty good. Lots of familiar trucks there. Several new ones. And, a few favorites noticeably absent. Went by to see Brocky, but he was chatting with some other guys. Next trip, he was off to answer the call of nature or something. Sorry, Brocky. Maybe next time! Met up with 1961H67. Good to put a face with the name. Can't wait to get over to his place and look around. Sounds like some interesting stuff going on over there.

Be sure to take Joey's advice with a grain of salt! Remember, he is still heavily self-medicated! Sorry, Jo-Jo! Could not resist pokin' the bear just a little bit! Hope you're up and back at it soon. Take care.

I'll try to find you guys. They setting up a tent with the chapter banner on it?

Holy Mother McFork! Take care of yourself, man.

Sorry to hear that. Hope everything turns out okay.

Headed down to Brad's show tomorrow with the grandsons. Hope to get a few decent pictures. I figure Brocky will be there. Hoping for a few others. Maybe Jo-Jo? Maybe Dean?

Ya' know, I can't help but notice how close our Matt is to that "other" Matt (Pfahl). Less than an hour away? And such similar, professional work? Maybe there's something in the water up there in Connecticut! Or, maybe I'm missing something?

Gotta echo what Glenn said. Springs don't get stuck. The plunger that the spring is attached to is what is stuck.

Cool. I knew the "C" came out right around the end of the B's run. Was not sure if any made it into the B. I think the earliest one I personally saw was in a '66 or '67 R. May have been some in the earlier U models, but I don't know. That configuration on yours is different that I ever saw. Can't be too many like yours. A rare jewel to be sure. I don't think they made all that many B's in '66 (last year). Thanks for the info!

The "C" was pretty common in later R, DM, U, and F models. Don't think they were ever original in a B model. Here is a .PDF of some info on that engine. The graph has the traditional signature of Mack engineer Win Pelizzoni on it. endt673c.pdf

Since finding pictures online is not easy, it may have been one of the more obscure models. Attached is the production list. Search the web for images of all the listed models. It had to be one of them! Mack Production.pdf

That's the way the Euclid dump trucks I used to drive worked! Most of these newer automatics use combinations of clutches and brakes to get different ratios through the planetary sets. Lots of weird goings-on in there.

Welcome. Love your handle! Pictures of the truck and any numbers you can find on it will really help identify it. There are guys on here who can really get into the details of the different models, if you can give them a little info to start with.
