Ray Sidella is one. He moved a truck for me back in 2022 from Delaware to Pittsburgh. At the time he made weekly trips to the Midwest back to East Coast. I don't know if he gets on here anymore but his user name is @mack mhe9. If you send him a PM he will gat an email notification. I think I still have his phone number written down somewhere.

Has anyone ever seen he loadstars with the one man, center mounted cab for hauling long beams or pipe? There is a roof hatch to get in and out. I think IH made them before the loadstar but they are neat looking. Only ever saw one in real life. 

My 1994 RD has a mechanically governed E7. No ECM. It has a cable operated tachometer.

There were a few loggers around here that ran 8V92 Detroit's in their Superliner's. Detroit's were real popular around here.

Do you know if a Series 60 Detroit ever made it into a Superliner?

Surely there was an owner’s manual with these trucks.  That would be some help.  If I see manuals for 600 series would that include my truck?

From what I've seen the owner's manuals was a generic book like what comes with a passenger vehicle. It was called "operators handbook" and just gave general information as to how to operate the various switches and things of that nature. It was not vehicle (serial / VIN #) specific. What you are a looking for are electrical shop manual items. I'm not sure if every truck built came with a shop manual. I think it depended on what the customer wanted and probably cost extra. A truck's shop manual was a binder that was labeled with the truck's serial/VIN and contained a variety of different system specific shop manuals based on the components included in the truck's build probably based on what the customer wanted. I've seen ones that were only one binder thick and others that were 3 binders worth of material. Buying any old shop manual or some type of generic "600 series" shop manual and expecting it to have a wiring diagram for a specific chassis is probably futile.

All,

Thank you for the response, it has roto chambers on it now. I'll have to look into the space issue, to see what will actually fit. I remember 20 years ago, there was a place in New Jersey that came up with retrofit kits to convert just about all of the stock applications, from the old wedge brakes all the way through, over to spring brake canisters. It's been soo many years that I lost track of them. I found out about them because I was doing a complete brake job on an R model tandem tractor and it made sense to go the extra expense to change out the spiders, and whatever else necessary, to accept the kit to convert to spring brakes.

I'll say that I tried to use "off the shelf" parts a couple years back to convert Rotochambers on a 1962 B81 to 30/30, 24/24, and even 20/24 chambers. Offset slack adjusters, rotating the spiders, didn't matter. I determined it to be impossible without a bunch of "design" and fabricating to relocate the chambers to a more inboard location on the axle housing. The only solution I determined would "easily" work was to obtain single acting, pull type, Haldex Maxibrake chambers ($$$$$$$$$$) and mount them to the frame on the opposite side of the slack adjuster as the Rotochamber and connect them to the slack adjusters with grade 80 chain. This would still require plenty of thinking, planning, and some fabrication to make happen but I figured was much less involved then trying to reposition 30/30 cans on an axle not originally set up as such. I never did undertake the project and have since sold the truck.

Read through this entire thread. It will explain it as well as the E7 LDA system. I went down this rabbit hole a few years back 

Sold For $5,564

Attention @mowerman. Not too far from Reno.....Would look real good next to your DM 🤣

Well I know next to nothing about E9s. However, in E6 and E7 speak the M indicates the engine is a Maxidyne high torque rise version of the engine. 

An ounce of gold has ballooned to $4,075. The same ounce of gold has risen in price by about 22% in just the last month and a half. That should tell you something.......

Mamdani is projected to win the Mayor's race in N.Y.C.  What i dont understand is, as an antisemite, how can he win N.Y.C.? Is there something wrong within the Jewish community in N.Y. C.? I saw footage of a Pro Palestinian rally in the streets of N.Y.C.

The Jewish population of NYC is reported to be approximately 1.25 million. The Muslim community is reported to be about 900,000. So roughly only 300,000 "Jewish votes" "matter". The other 7,300,000 people in NYC probably don't care about a land border dispute 5,500 miles away as it pertains to who their city mayor is. My guess is they are probably more concerned about social, political, and economic issues within NYC and align more so with Mamdani on those things than any other candidate.

OPINION: I haven't been watching Mumdani's every word and action. With that said I haven't seen or heard of him being hostile or prejudiced toward Jewish people. I don't think being pro Palestinian automatically makes one an antisemite. I think it is possible to be critical of the Israeli government and not be an antisemite. Mumdani said yesterday:

“Two years ago today, Hamas carried out a horrific war crime, killing more than 1,100 Israelis and kidnapping 250 more. I mourn these lives and pray for the safe return of every hostage still held and for every family whose lives were torn apart by these atrocities”

Haven’t seen many out where I am in the Massachusetts and Rhode Island area.

What have you been looking at? 😁. Your in New England. Just about any vocational Mack older than 2007 (maybe newer) will have those axles under it. There has to be a litany of of those trucks still running around up there. You asking about an axle and carrier design with at least an 80 year legacy and have been essentially unchanged over that timeframe. Of course there are pros and cons when comparing them to other axles, however, generally speaking they are probably some of the most robust axles available without getting into specialty stuff. Of course this is a Mack forum so the information may be biased but I have never known anyone to dislike that setup for heavy duty work.....

$20,000,000,000. Where is that money coming from? 

Trump to Ask China to Buy Soybeans. Why It’s a Hard Sell.

"U.S. farmers have been losing share to Brazil and Argentina as a result of the tariffs. That hurts, especially because the U.S. has said it would allow Argentina to tap a $20 billion swap line and floated the possibility the U.S. would even buy the government’s debt."

Here is the FB link for anyone wondering. Facebook location says its in Binghamton, NY. The phone number indicates Long Island. The background of the photos look more like Binghamton to me.

There are so many things about that event/day, the events leading up to it, and the events following that are just so eerie and bizarre. Its very difficult to believe all aspects of the official narrative.

the 12V71 would be a beast.

I always have wondered about them. They are "only" 852 cubic inch, which is essentially the same displacement as a small or big cam 855 Cummins of the day. My guess is probably more horsepower than its contemporary Cummins and Caterpillars but probably equal or less favorable torque curve too. I would have to think they are extraordinarily smooth pulling engines. A 4 stroke V12 has a 6 power strokes for every crank revolution, or every 60 degrees. Versus 3 or every 120 degrees for an inline 6. A 2 stroke V12 is getting all 12 power strokes every time the crank turns, or 1 every 30 degrees. Like I said, I would have to think they are incredibly smooth and probably have a very different feel versus a typical I6. I would like to drive something with one it someday just to see but probably wouldn't want to own one. I have a friend who pulled very over length and overweight precast bridge beams with a steerable jeep in the rear back in the late 70s and early 80s when they were finishing the Interstate system around here. He ran a Kenworth with a 1693 and later a transplanted 855 Cummins of some variety. He ran with a guy who had a 12V71 in something pulling the same loads all the time and he says the two of them were always pulling grades at the same speed and they were about equal in performance. I have no other knowledge of their trucks' specs but that what his story. Have you every run one empty or loaded? If so what was your experience with it?
