Okay, here are a few from 1966. Picked up a couple of 700 series in this group.

Looks like the Stemco-Kaiser K534M may be discontinued, too. Maybe E4465B Euclid? Some possibilities... https://www.ebay.com/itm/266236271524 https://instockmotorsports.com/mack-301sq32b-king-pin-kit-nos/

I doubt the Mack parts will be available. But, Like JoJo says, there are aftermarket suppliers who can use the factory part numbers. I think mine were Stemco-Kaiser. Here is a clip from an old service kit list. Looks like Mack had discontinued these even back then. Might try reading this link...

This is for you, Bob... Oh, without me looking back through all of this, do you have that VIN handy? R-U-DM Unit I.D..pdf

I will start by sticking some 1965 vintage images in here. Let me know if this is interesting to anyone...

Either wheel bearing adjustment or kink pin wear. Here is the most likely Mack part number for a king pin and bushing set: 301SQ32B FA500/501/505 (Prior to 1963)

Uhhh…no! I just know what the letters meant! You’ll have to help him with the actual mechanical stuff!!!

I'll be glad to post what I have. Just like to know how it would work best for the guys. A Wiki article? A new "Old Brochures" thread in the antique section?

Y'all let me know what you think about where I could post more of those. They might be good historical information for somebody sometime down the road.

You can trust those numbers then!

Yes. At one time, they were one of the biggest clearing contractors in the world. My great-uncle, Ted Jordan, was "Big Ted" and his brother-in-law, Ted Phillips, was "Little Ted". Locally, they were known as "Ted & Ted", or just P&J. None of the Jordans are involved with P&J any more. They all went on to retire or start their own businesses...to more or less success! Avis Phillips (Little Ted's wife) is still chairman there. Ted's son is CEO. They kept the Phillips & Jordan name, though, because it is pretty well known. https://pandj.com/our-history/leadership/

I have these (very) rough scans of a bunch of the old brochures. I would love to screenshot as many of them as I can and post them on here somewhere. Maybe in the wiki section? Some would be hard to read, but on some you can make out the different engines between different models, and you can always see the number of axles! What does anybody think???? Here's a sample (1965, I believe).

Did you get the VIN off the frame yet? I got lost in some of the history on this one! I get lost pretty easy anymore...

Actually, I just found a brochure in my list showing an "R700S" tandem-axle truck that was not an "R700ST" tandem-axle tractor. So, they must have just decided not to use the "P" in some applications. That brochure was a 1972. But, I found other brochures as late as 1976 that still listed certain models as "P"s.

Yes, "T" would be a tractor. "P" would be a platform (straight truck). Not many "P" trucks around, from what I have seen. Mostly tractors. An "S" would definitely be a tandem. An "ST" would always be a tandem-axle tractor. An "S" could be attached to either "P" or "T", I suppose. But I don't know if I ever saw an "SP". "X" was heavy-duty. "SX" would be a heavy-duty tandem-axle. They used that same nomenclature through a lot of the models. B, F, R, U, DM, just to name a few. Another elegant system Mack used, that Volvo never gave a rat's rear about.

Can't go too far wrong that way!

Yes, the VIN should be on the outside of the RH frame rail, between the axle and the cab.

I never got to drive Herman's truck. Can't even remember if it was a B81 or a B83. First one I ever drove was a B61 belonging to Phillips & Jordan. My Dad had driven that particular truck from the time it was practically new. That's the one I learned to drive on. N/A Thermodyne (185HP?) and the 18-speed Quadruplex. First one I was ever paid to drive was the 1967 R611ST. 250HP Thermodyne and the same 18-speed Quad. Still, those B80's stick out in my mind. All the ones around there had the "oil field" fenders. Lots of them were triple-framed. Huge spring stacks. Some had the 22" wheels instead of the 20s. Noticeably taller than the B61's. Absolute beasts of trucks...with that same tiny little cab! Funny thing was that most of those operators painted the trailers to match the tractors. Herman's was red with a triple-axle Hyster lowboy painted to match. The B61 I learned on was yellow and black, with a yellow tandem-axle Hyster trailer. Almost like they had some pride in their rigs, ya' know? Of course, the white R611 just had the standard yellow Hyster tri-axle behind it. White tractor goes with anything, right? I can't wait to see hicrop can do with this one. I'll be riding down that memory lane every time he posts a picture on here. So, thanks for taking us along for the ride! Hurry up! More pictures!😄

Every time I see a red B80-series, I remember the one I rode in with my Dad when I was a little guy. It belong to Herman "Bull" West. That sucker would beat your brains out! Heavy, heavy built truck. Funny, they didn't seem all that old then. Of course, it WAS 50 years ago or so...

That made my head hurt...🤪

I traced the owners of that truck a while back. Found a few owners. But I never found where Carey Loftin ever owned it. But, records aren’t all that good from that time. Anything is possible. Carey Loftin was maybe the best stunt driver ever.

That reminds me of a time when I was still too young to drive. Was on a clearing job with my Dad. We were waiting on the fuel truck to show up. Seems like it was a C60 Chevy. Waited. Waited. Waited. He decided to back-track and see if the fuel jockey got lost or stuck somewhere. Found the fuel truck butt-down in a creek, having fallen through a covered bridge. Nose was just coming out of the bridge when the drive wheels found the weak point in the middle. Splash! Nose up on the edge of the bridge, tail in the water. Seem to recall it took a bit of doing to get it up out of there.

Is the oil pressure relief valve boned and pumping stupid high pressure up there?
