Trailer had eight tires. I don't know anything about the history of that trailer, probably been cut for scrap by this time. Another thing I noticed about the picture is that most of the tires were well worn. My grandfather mentioned to me that during the years of WWII, tires, fuel and new equipment were all hard to come by. He operated the 54B shovel stripping for brick clay. He owned the shovel, a couple big Cletrac dozers (because Cat's were impossible to find) and International dump trucks.

I don't think that bracket was ever a factory option, I think it was after-market. I had one on my 57 Diamond T (which used the International cab)

Mack offered these as an option, switches pre-wired for future installation of what-ever. One was hot all the time (battery), the other was only hot with the ignition switch.

The AI / AC designations have to do with EGR. 2004 model year was the first year for the ASET (application specific engine technology)(A) engines, AI for internally cooled, and AC for externally. The AI engine used an additional bump on the camshaft to pull back a portion of exhaust to mix in with the next intake stroke. The AC engine used an external cooler. The two engines were not interchangable, if you bought a vocational truck, you got an AI, if you bought a highway model, you got an AC. Both had their problems, the AI's were poor low end performers, and accumulated alot more contaminates in the crankcase, but were fairly reliable with "old style simple" turbos. The AC's generally performed fairly well, but were plagued with exhaust manifold leakage, and (VGT) turbo, and cooler problems. With both engines, maintanence is very critical to follow recommendations.

I forgot about the service truck, I think there are pictures of both on the Gerhart web site.

Ya, he's my body guard, he makes me feel safer when I get on this site!!

There are a couple here. There's a U747 with a Cummins, there is a U600 tandem tractor with an 864 V8, and a ten speed splitter trans, and there is a sweet little single axle with an 864 V8, factory Fuller 15 spd trans, and disc wheels. Brian Krois has posted pictures of it before, it is green and yellow, and usually hooked to a yellow bath tub dump. I don't have any pictures at the moment.

I can't say about that truck, but a single axle DM was a factory configuration. We have a DM single axle here, it was a heavy lowboy tractor sold new to General Crushed stone, it has a double frame, and heavy (29,000#?) rear with cast radius rods & 24" tires.

No, the trailer Roger has now is a cable detachable gooseneck that came from Hawthorne's in Philadelphia. The gooseneck on his trailer could be detached, or the running gear could be detached, one or the other, or both. The Bucyrus Erie shovel in the picture was probably from the late 1940's, and the working weight was right around 150,000#.

Note the cut outs in the bumper on either side of the fog lights, finally got some tow clevises in there! This truck was at mid-America, and is now at the Customer Center.

I just thought I needed a change. The bulldog picture is on a wall at the Mack Customer Center. It would make a great wallpaper picture.

Looks really practical, I wonder what application the owner had in mind when he built that?

The early Rogers "wobble wheel" trailer is fixed at the front, and the running gear detaches from the rear, and rolled away by hand, the shovel is run on and off from the rear, all done manually with blocks and jacks.

Seeing the Sterling chain drive picture in another topic reminded me of a little story. These pictures were taken somewhere in west/central Pa. R.R. Schubert was moving my grandfather's Bucyrus Erie 54B shovel when they had a little problem crossing this bridge. They unloaded the shovel, picked the tractor up, walked the shovel through the creek and loaded it back up on the other side.

I looked at that truck years ago, the owner was crazy on the price, I think it was in the $15,000 range. Been sitting outside for a long, long time. It would be a frame up restoration.

I just hope it didn't have a Detroit under the hood!!!

Jumper I wouldn't have wanted to be around you the night I took this picture, it was about 3 o'clock in the morning, (2) M45 Macks and a P12 Pacific, all powered by 16V-71's, pulling over 2 million pounds up a 2 mile 7% grade. There was more smoke comming out of the bottom of those engines than came out the exhaust. I think you would have lost your mind!

I was never a big DD fan, but the people I know that ran those liked them. As far as "best engine", there may be some resistance to that statement on here.

Relax Vinney, with a reconstructed title, the only thing original about that thing is the serial number plate.

I agree with what's been said here already. As far as replacing the rivets, you really don't have a choice, grade 8 bolts into ream-to-fit holes. For what you're going to do on a truck like that, I think to weld the cracks would be acceptable, cut the inner frame back farther so as to stagger the joints, and to get weld inside and outside of the outer rails.

With most Mack camelback suspensions, shock absorbers were an option, but I just don't remember if that was so on the ST. It may have even been an option on one axle or both. We have an MH with ST, I'll check tomorrow if it has them or not, but I think it does. Usually that stuff is there for a reason. There were two different styles of rear taperleaf, one was under the trunion bar and one was over, which style is yours?

That's pretty common. I believe that was factory option.

The CL was owned and operated by Dick Parsons from Newville, Pa. I'm sure you did see it at Antrim. The fuel on the E9 had definately been tampered with. The picture was taken in up-state New York, the 88B shovel was being delivered to a collector. Before the CL Dick had owned a Superliner, similar paint scheme. The CL in the picture now belongs to Roger Gerhart in Lititz. Parsons still runs a CL, but with an ISX 565 Cummins. He'll be the first to tell you it's OK, but it won't run with the E9
