Starting at the lower right and ending with the upper left (I know its kinda Chinese or something) is how a power transmission shaft tries to distort as you hit each critical speed. Think of an out of balance tire. You hit a speed and it's bouncing, speed up and it smoothes out, then you hit another bouncy speed and so on

When I was in school we didn't have "driveshaft calculators". We had to do the math with a pencil and paper and a slide rule. I had to walk there in torrential rain wearing a yellow rubber rainsuit and galoshes. Uphill both ways

Yeah I remember going over that in school. Thinking they were called "nodes". When you hit the first one it tries to turn the shaft into a banana, and the next one tries to turn it into a sine wave shape. Somewhere here I still have a big textbook about power transmission shafting

0.74 ish has been common ever since I can remember. A TRQ7220 was 0.66, a 2050 was 0,60. I think that "High Hole 2 stick based on a TRL107 was like 0.66, and the RTOO9513 in that A Car with the 2 speed Eatons was like 0.62. I'm a firm believer in low axle ratios, but then again I've always been a more or less local guy. i never had any desire to run OTR where a little bit of fuel milage can put you in the red. As my grandmother used to say "I'd rather pick shit with the chickens"

Or lots of overdrive in the trans. Gear it in the 9's and put a Spicer 1241 in it backwards, then you can run that motor as slow as you want lol

I just like to have the torque multiplication as close to the work as possible. Ideally like planetaries, but they can get kind of heavy

I borrowed a 4 axle tractor to do moves a couple of times that had a 460 in it. I wasn't very impressed. I think my juiced up Big Cam IV would give it a good run. It was a nice enough truck, but it wasn't what I expected out of something that was a 460

I bought a big Vac truck off of Occidental chemical one time that was like 15 years old with 5000 miles on it. Never even titled, but a ton of hours on it running the pump. I don't think that is all that unusual in this application

Yeah, these were all 13 double overs with two speed rears. Easier on the driveline, and easier on the frame and engine/transmission mounts. None of that driver's side steering tire coming off the ground on a hard pull.

eah I saw that late last night and thought Oh God. Lots more info needed. Not to mention, that 18 speed Eaton better be cheap or free

Looks good to me. That is about where I like to buy them, usually a little more than 10 years old. They get cheap, all the problems are known, enough of them in the salvage yards, plenty of aftermarket parts too. Not to mention there is no need to insure them other than liability. Sure a few thousand if they are a total loss sucks to lose, but it's not going to ruin you financially. A new F250 cost almost as much as I paid for my garage and property in 2015. That's crazy. The auto makers have gone nuts. I don't even want a touch screen and an infotainment system. Hell my buddy has a model A Ford that he uses a lot for running around town. It's a little tight for us because we are both big guys, but other than that I could use it for a daily driver. Convert it to 12 V neg ground so I could have a radio and modern lights and I'm fine

Even if it was real, I wouldn't be able to afford it. The last time I could afford a new pickup, it was about $7,500

That is your typical owner operator steel hauler pulling coils out of The USS Fairless Works in the 1970's. They would all be leased to Tryon, Cannon, Pyle Transport etc. There were guys running with the tag from their pickup truck, regrooved recaps, home heating oil for fuel, hissing air leaks, trucks that had to be parked on a hill so they could start them from a roll, coolers full of beer in the cab,. I remember an older guy from my neighborhood driving for my buddy's father got to the gate at the mill, and opened the passenger door and it fell off and smashed his toe. And my buddy's dad blamed him for "Opening the door wrong". They got in a fight and didn't talk for years lol

Hazleton Pa, in a 9,000 plus square foot garage on 3 acres. It was one of the maintenance shops for a local mining operator.

If you look at the picture of the LF dump, you can see John's single axle Brockway wrecker. I believe it is a 1946. John towed with that truck all the way up until the late 1990's pretty regularly. The last time I saw him use it, I helped him hook up a ford L9000 beside Eugene's shop on East Tioga, and I had to help him get up in the cab of the Brockway. And off he went to Allentown to drop it off. No Idea how he got it dropped there maybe somebody helped him. Last I talked to Stevie (his grandson) he still had that and the Green KW T600 John bought new

How about John Griffin from this place on Masher street. He had all the Brockways. I used to keep in tough with his grandson Stevie, but I think It's been like 10 years since I've talked to him

No Eugene ended up with it, But after he died in March of 2015 everything turned into a cluster F, then his wife died and I lost track of everything. Did you know Eugene

It's like heaven, if heaven had anthracite mines and breakers

The LT might bring some money. The little L cab needs a bit of work. The 281 single axle wrecker is interesting, but no under reach and the wrecker is kind of light and no serious winching capacity, so that is just a toy too. It's not like you could put it to work. Other than the LT I don't see anything bringing five figures

When you open them up that big there are a lot of structural considerations. Probably be fine if you are building a trailer queen show truck, But if you put it to work you better have added some structural reinforcements or else that cab is going to crack starting with the upper rear corners of the door frame and getting worse. Have you ever seen an R Model that has been run with the bar between the steering axle's spring hangers that everyone thinks is just to hold up battery cables and the fuel crossover, missing or loose? It'll break the cab up just like that. And believe me, that is a hard fix

It's a small cam Cummins, and most likely a RTO95****** trans that is only rated for a 900 foot pound engine. Maybe it's got a 2 countershaft Spicer 4 way in it if you are lucky like a 1241 and you can run a 9 speed in front of it

I don't know if you guys remember Tom Zacney. The LF below was his before he died. He had a really big collection of Macks, all kinds of stuff When Tom died he had a lot of cool trucks, Heavy spec L cab stuff and all kinds of things. All kinds of conditions, lots of them ran and drove. All the collectors that wanted them so bad wanted to pay less than scrap value. So much of it ended up going over the scale at Allegheny Iron. From my experience most collectors talk a great story, but never come with the cash. They want you to hold on to stuff while they think about it, and talk BS
