6NZ is a C-15, and a highly sought after pre emission Cat motor. Often referred to as one of the best Cat motors produced. 

Isn't there a fairly significant difference in "C-15" engines vs "C15"? I think the C-15 was only made for one year and then it became the C15, then ultimately the C15 ACERT. I don't know what makes the C-15, other than the valve cover, different from the C15 but if I recall correctly it was a more desirable arrangement.

i figured the plumbing would be the easy part. 

oops, i was wrong. 

I was always told the first rule of plumbing is: Always have a full tank of gas.....

Aren't you worried that the gas company will be upset with you?

Na. I wouldn't care if they were. Years back when I moved in I started burning wood and they came out several times to check my meter to make sure it wasn't broken or I wasn't bypassing it. They gave up after the second winter. They should be grateful. I buy their gas for hot water heating, clothes drying, and cooking. I all fairness street natural gas in most cases the lowest cost per BTU of just about any mainstream energy source. I just prefer the radiant heat the stove puts out and how much more comfortable the house is vs running the gas furnace. Also I like to have options. I can heat with natural gas, coal, or in about 20 minutes after the coal fire would go out I could switch out the stove for a wood stove and be heating with wood. I prefer heating with anthracite coal for many reasons but could utilize my other sources if necessary.

Probably some not cheap beast with V8 (I can't see the price and don't need that) but looks really fresh. Thanks for posting

They are asking $18,000 US Dollars and if it does not sell by 1/15 they are sending it to an auction. 

From The Listing:

This machine is being sold by norsemenauction.com. It is available for $18,000 USD. If it doesn't sell, it will roll into auction on January 15. The last available bidding day will be January 31. Additional photos and videos available at norsemenauction.com Chains and tools NOT included - Fantastic Condition - Clean Interior - 319,084 Miles - Mack E9 Engine - 440 HP - Turbo - Engine Brake - Differential Lock -12 Speed Manual Mack Transmission - 8x2 - Rubber Block Suspension - Drum Brakes - A/C - Power Steering - Headache Rack - Wet Kit - Mud Flaps - Heated Mirrors

I figure the easiest way to repair it for a hobby truck is to pull the 5th wheel off and drop the axles and suspension completely out of the truck. Drill the ends of the cracks, and weld it up. Then lay a channel insert on the inside of each frame rail going past each suspension mount at least 2' and bolt it all back together. Any crossmembers in the area of the insert will have to be shortened accordingly. But in your situation where the truck has already been stretched it may be better to just cut off the bad section and start over. Either way its a pretty big job.....

Got some bad news on the truck...I pulled it into the shop today to do some work on it, and I made the mistake of looking at the frame rails. I'll probably end up splicing in some new rear sections since the truck has already been stretched. I can't tear it down yet; we will be moving at some point because they are "industrializing" our area and we bought property a little farther out. We have to build a house and shop so that will take a while, I don't want to tear down the truck until we move.

That frame failure is a hallmark of the Hendrickson RT walking beam suspension. For whatever reason the stresses that suspension puts on the frame rails cause the lower flange to separate from the web along the radius of the bend between the two suspension mounts. I have seen it on many Hendrickson RT trucks. In fact my 1974 White Road Boss has the same deal going on.

I reckon this would make quite the cool camper for a month or two

Don’t end up like Christopher McCandless in that thing…..although his bus was an International KB5

If you want to know if he still has it you should send him a PM. If you send him a private message he will be notified by his email. Since he hasn’t been on her in a couple years he will probably never see this but I would think if he got an email notification he would get back to you.

No too many people know very much on the Midliners around here anymore. I would suggest picking up some service manuals on Ebay. They seem to be plentiful. Getting parts for them seems to be very problematic these days. 

Here is a better video and explination:

Had to look it up myself....Apparently (from the comments and how Otherdog says) the second guy to use the saw in the video is using it properly. Digging the cleats into the ground between you and the log and rocking the saw forward allowing the saw "tip" to pull itself into the material.

Yes very sad to hear this. Was he elderly?

Yes very common in waste facilities and Landfills where they use tipper trailers. A friend of mine had a DMM 6x6 with one on it. It was an ex Waste Management rig from one of their fill sites. He ended up selling it to another trash company that had a transfer station.

Also NVR homes prefabricates all walls for their homes in a facility and bundles them up. The entire house is framed in that facility. Then they lay all the walls, bundles of plywood, and the rest of the home's material to a flatbed trailer and haul it to the lot it is going to be built on. The trucks that pull them have these types of 5th wheels. The driver removes a bunch of straps and the the entire load gets raised and slid off the trailer onto the ground next to the completed foundation. Pretty wild to see......

were you the one a number of years ago looking to turn your Virginia property into a retired Veteran community? I thought that was a great idea, was annoyed to hear how much of a roadblock the local government was on it.

That was 41Chevy. He has since disappeared. I read a while back some were speculating he had passed on. 

Wow. Air over hydraulic brakes. I have never seen nor heard of that on a Mack. What would be the benefit of doing this? I mean you already have an air system and are using rotochambers to actuate. Why would one decide to actuate a hydraulic master cylinder rather than a slack adjuster? I'm curious.

I would repower/regear an original truck. My personal opinion is medium/heavy duty bodies swapped onto a pickup chassis look like clown cars to me. I have a friend who put a B model cab and front clip on an international S series chassis and it turned out very nice.  I would look for an International/Navistar mechanical DT360 engine. They are the same size (360 cu in) and dimensions a 5.9 Cummins and just as bulletproof. Plus nobody has one. A 5.9 swap is so tiresome. I like the 2 speed rear end especially if you are going to be hauling weight. The one in that Diamond Reo is probably geared super deep though. I would look for an old International S series parts truck or 90s Ford F700 with 2 speed rear for the axle and transmission. Whether or not you decide to go air brake or hydraulic brake will dictate a lot about what axles/ratios are available to you. Either the DT360 or 5.9 Cummins can be outfitted with an air compressor so it would be possible to do either hydraulic or air brake.  Good luck.

Red air valve, see attached photo.

Thanks for your time and knowledge,  much appreciated.

 

Ok WOW. WTF even is that thing? Are you able to trace the lines going into and out of it? Where does the cloth braided line feeding it come from and where does the plastic line coming out of the brass 90 elbow go to? It also looks like it has a grease fitting on the end of it????

Also its pretty strange it is a straight truck and has a red button only but that could just be the old yellow diamond got brittle and and broke. The the old red/yellow buttons were removable off the valve with a small roll pin. Maybe they just threw that red button on the valve that should be there. Does the truck have hookups for an air brake trailer? Notice it says "trailer air supply".

If the Volvo turds had continued advancing the V8 They may have Easily surpassed 2000 ft lbs by now ! Use the Scania as an example! The original V8 and Scania were Closely linked at one point! And The Engines would sound better! 😄 Apart from a locomotive!  Nothing beats the sound of The V8 !

I personally think Mack should have poured their resources into developing the Mack "Big Six" prototype that is at the Mack Museum. It would have been directly competing with 855 Cummins and 1693/3406A Caterpillars at the time. Given Mack's engineering prowess at that time, they would have had an incredible big bore, inline, "highway engine". While cool, the E9 should have never been. Mack should have let the V8 die after the 855/856 V8s. Its easy to say this in hindsight but I think the E9 ultimately handicapped Mack...

Now that I look at the first picture of the chamber more closely I see it is just behind the cab on the passenger side next to the exhaust. With the amount of wheelbase the truck has its hard to believe it is part of the braking system. What is it doing? what does the end opposite of where the airline is going in look like? Does it have a long threaded rod coming out of it and if so what is it connected to?

Try not to vomit when you see the price.....

That is an old Rotochamber......YUCKKKKK! Its hard to see from the pictures supplied, but is definitely a rotochamber of some sort. The ones I have seen are just single acting service brake chambers like a steer axle chamber. No spring brakes. My B81 had them and just had a brake drum on the driveline for parking. The other ones I have seen were on a DM800 but also had single acting, spring, pull type Maxibrake chambers opposite facing of the rotochamber connected to the slack adjuster with all thread or chains. if there was a loss of air the spring maxibrakes would pull on the slack adjuster.....Very queer setup but was a solution before 30/30s and similar were common or perfected. I don't know if the truck pictured has Maxibrake, pull type chambers on it but what I am seeing in the pictures is just a single acting rotochamber for service brakes. Very obsolete an insanely expensive to replace if you can find them. Like $600+ each. I think they are serviceable and there is just a regular rubber diaphragm in them if they are leaking internally. Very hard to believe these are on a 1979 but hey anything is possible. 

Does the truck have a yellow air valve on the dash for parking brakes? If not then I would guess the brake lining is stuck to the drums. Sledge hammer is in order.....
