Now that brake pedal's been stomped a few times!!

From Wickerpedia: In 1963, after Marmon-Herrington, the successor to the Marmon Motor Car Company, ceased truck production, a new company, Marmon Motor Company of Denton, Texas, purchased and revived the Marmon brand to build and sell premium truck designs that Marmon-Herrington had been planning. The Marmon truck was a low-production, handmade truck sometimes dubbed the Rolls-Royce of trucks.[citation needed] An overcrowded American truck industry and the lack of a nationwide sales network led to the eventual failure of Marmon trucks in the USA. The last Marmon was made in 1997, and the production facilities in Garland, Texas, were taken over by Navistar’s Paystar division.

The measurements look good; the one with the adapter has a 1-1/2" input shaft and the other has a 2". I think I can just swap the disc because the flywheels, pressure plates, and the pilot bearing are the same. The transmissions are completely different; the one has 2 internal shift forks but the other has an external rod to shift hi-lo. The housings are completely different, but it looks like all the attachment points are the same.

The 673 I'm using for my 1960 H67 is out of a 1958 H67; the transmission has some issues so I was hoping to use the trans out of my 1959. As you can see in the photos, the '58 has an adapter ring on the bellhousing (the flywheel housing on the '58 engine is shallower). Does anybody know if I can just swap the adapter onto the '59 transmission? They're both duplex transmissions.

Tom1361, did you figure something out on this? I have a FA511 axle on my H67; I found an NOS Moog 8482b kit on ebay that crosses to Mack 301SQ32AC (I wonder if it's supposed to be 301SQ32C). It says "catalog shows these correct for FA45, FA401, FA501, FA511, FA400 and FA500 axles". The pins in the kit measure 7-3/8" long by 1-1/4" and 1-1/2" diameter. As you can see in the photo, they have roller bearings but no seals. I'm not going to do my kingpins right now but I wanted to have these on hand in case I need to. If these pins sound right for your axle, you could watch for a Moog kit to come up for sale.

If it has an 8" crack, it doesn't seem like a good idea to overhaul. I would start with a good block.

Sorry to all you Marmon fans, but that is one of the ugliest trucks ever built.

I taught all 3 of my sons to drive on manual...I wouldn't let them drive an automatic until they could drive a stick. I am constantly amazed at all the people I meet in the US that can't drive a stick.

Lots of clearance in those fenderwells!

Yes, that's the truck.

AZB, is the Cobra body fiberglass? Is it chrome? It sure looks like it.

Does that say E9-1200? Does it really have 1200 hp?

That McDonough truck has a sleeper so it makes the cab larger in the back.

My middle son is 25 years old, when we want to watch a dvd he grabs the 3 Stooges. He thinks they are hilarious!

I saw one at the truck show in Newark Ohio last year, I think it was mostly for show...milled and polished really nice. Not so much for just an everyday work truck.

A 77 CL wouldn't have a 2 speed rear, would it? Could it be for antilock brakes?

Those are some Macks you don't see in the US.

No, you were facing your computer the wrong way when you looked at them.

There's a Large on ebay right now, but the iron-on looks kinda crackly. https://www.ebay.com/itm/Mack-Truck-Shirt-Trucker-Semi-Vintage-large-black/223024750746?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160727114228%26meid%3Dade113c323d8461a8181211cdf90f6af%26pid%3D100290%26rk%3D4%26rkt%3D4%26sd%3D153059645699%26itm%3D223024750746&_trksid=p2060778.c100290.m3507

So those voices are not just in my head?

I knew Aussie truckers were some tough guys, but stopping without brakes tops the list!!

8 metric tons = 17,600 lbs. I think that's on the heavy side; my H67 single axle with 673 weighs 10,000. I'd say that LJ is somewhere close to mine or Hobert's B model.

That is really a nice-looking truck!

Black is good except for when you're out in the hot sun.

Also make sure your thermostat is good and the water pump is circulating correctly.
