It looks like it would make a solid start for a restoration project.😃 But, that is typical of any old B model Mack.

We need pictures for those of us who don't know how to read!

That truck is just so cool!! It looks like it is coming along very nicely. That is a vintage of Mack when men were men, the women were tougher than nails, and the USA was the mightiest industrial powerhouse in the world.

Is it a SX version? What is the load capacity of the rear axles?

Hurstscrambler, No, I volunteered to lower it to 3k. I think that is fair. The truck is getting to a point that she is in need of a lot of work, as you can see in some of my photos. Thanks, Job41

A business man who owned ships in the early 1800's wrote a letter to Alexander Hamilton about his problem he was having with pirates. He asked Hamilton if the second amendment allows him to put canons on his ships so that his crews could defend themselves. I can not remember the exact response of Hamilton but to put it simply,he wrote that it did allow him! Taking a slightly different tact but is absolutely pertinant to the discussion of the second amendment is the terminology of that time has to be understood. In the second amendment, something people like to misinterpret is the term "well regulated militia." The term well regulated meant timely, or quick to respond. Clocks were often referred to as regulators. It had nothing to do with restricting the type of firearm that you owned. In fact if you showed up to volunteer in George Washingtons army and you did not have a firearm with you, he would be blow his head gasket (quite angry!). He complained about it in some of his letters. Best Regard, Job41

The old Autocar is sold. It kinda makes me sad to see her go. On a positive note, maybe someday I will be able to pick up a good B model.

I am loading more pictures to give a better idea of what needs to be addressed on the truck. I have had a few people look at it expecting they could just put it on the road immediately and then find out it is going to take a number of weekends to make her road worthy. May I also point out that most of the lights are not working. The low air buzzer isn't working. I want the guy who purchases it to know what he is getting into and be satisfied with the purchase.

To everyone at BMT, Yes, the Autocar still sits in my yard and is still for sale. I haven't started it up in 3 or 4 months, but if I charge the batteries and hook up the block heater for an hour or so she should fire up.

More information would make this posting more interesting. Is the transmission a duplex, triplex, or other? Does it have the original engine? What is the condition of the cab floor?

Here are few more pictures to clear up questions some may have.

Rustydog, I thought it was a fair price, but a few years ago I had put it on CL for $4000.00 and the best offer I got was $1800. One guy offered me a Chinese made four wheeler (quad). I guess big heavy duty single axle dump trucks are becoming like white elephants. Contractors would rather buy a ten wheeler or a tri-axle dump. I have used it more as a horse than a dump truck. I have moved my old backhoe and my old D6 Cat with it. Don't tell anyone my D6 9U weighs twelve tons but my trailer is only rated for nine. However, those were usually short little trips of no more than seven miles taken slow and easy. The Awful car ( my brother's term for the old girl) handles it quite well. That reminds me of another bit of information which I should relay to potential buyers. It has 18 inch diameter brake shoes, which are quite expensive. The current set are in good shape. Job41 I

TozziWelding, Thanks for helping to get the word out. Here is another picture for the viewers' perusal.

Heavygunner, It would cost a couple of grand just to have it hauled to Montana. By the way, I think she tops out at 65 mph, and that would be with the engine cranking 2100 rpm and both trannys in overdrive.

1978 Autocar single axle dump truck. Cummins 250 with a 335 injection pump. The Five speed Road Ranger is followed by a 4 speed air shifted Spicer auxiliary transmission. Ten foot Box. It has a 20k front axle, and a 29k or 35k Eaton rear axle. I would guess it has less than 100,000 miles on it. Hub meter says 51044, but I don't think it was installed when the truck was first delivered to the town of Maine, NY. The truck saw very little winter operation as it was an asphalt hauler, and was never fitted with a plow, nor a salt spreader. I have owned it since January of 1998 and have put only about 10,000 miles on it. I have installed several items over the years such as compressor, rebuilt steering box, factory rebuilt injection pump. I built a set of fenders for it, after I had an accident in 1999. The box has a 5/16 inch floor, which I installed back in the day when I believed everything had to be extra heavy duty and I didn't worry about her empty weight. She weighs around 20,300 pounds. Needs the tail gate rebuilt. It needs tires and a lot of other TLC. I hate to sell the old girl but I am in a pinch. I can't seem to find the time nor cash to restore her. She deserves a good home. $3200.00

Need Pictures. Especially those like myself, who don't know how to read, need visual.

Wow !! That is a gorgeous truck. I would love to have one like it, but then I wouldn't be able to drive it.

How good was air assisted steering? I have never driven a truck that had that feature. I have heard some drivers say that it has a funky feel about it.

Sodly, I am not an expert on Mack trucks and the various models. However I am an engineer and know something about structures. In the area of the front axle the biggest affects on the frame are shear forces. Cross sectional area of the frame rail is what resists that shear. Also, Mack used a very high strength steel and therefore does not need a lot of steel to resist those shear forces. Frames need to be deep when there is a lot of bending force. ( In engineering terms we call it bending moment.) That would be in the area half way between the front axle and the rear axles. So manufacturers can make frames shallow in the regions of high shear and deeper in the regions of high bending. This understanding allows the truck manufacturer to make decisions in order to lower the height above the ground to the top of the truck frame or lower the region around the engine. Some manufactures keep the same depth of frame rail to make manufacturing easier. I hope this helps. Unfortunately, I don't have the time to write out a better explanation. Best regards, Job41

It is a good project truck for someone who is feeling ambitious and has some time on their hands. That is the trouble these days is to find time to do extra projects. Is the frame rail starting to delaminate?

Nice looking old R - model! Did the 1970 model year trucks still have a steel dash board? A few pictures of the interior and frame would be nice. Is the three speed auxiliary transmission shifted by air or stick?

The E models had such class! It would be a really cool truck once finished up. It is a shame to see her sitting out in the weather in primer. Was the frame blasted and then all necessary coats completed? It looks to be in a glossy black.

How well did the TRQ stand up to the torque of a 335 Cummins? I would imagine that you would have to rebuild them more frequently.

What transmission would be behind that Cummins? I tried to use the BMT Wiki, but the pdf data sheets will not show up for me using this new site.

Nice Rubber on the back. Are the extra fenders in good shape? Also pictures of the cab floor would really help.
