Another thing to consider, if it did push significant amount of coolant through the air drier, then a complete service of the air drier is warranted. You said you drained the air tanks, was any antifreeze found when they were drained?

It sounds like a blown compressor head gasket. One thing that can cause that is a coked up discharge line between the compressor and the air drier. Make sure to check and see how well air can blow through that line so you don't blow the head gasket on the new compressor. When you have the compressor off, disconnect the line from the compressor at the air drier and use an air gun to blow through. It should blow with almost no resistance to air flow.

Honest, and you can sleep well at night if he still goes forward with the purchase.

I would say in the country, there are a whole lot more people who are center left, that don't like what they are seeing and not "left wing". There are extremest on both side of center, and being on "the other side" doesn't make you an extremest. Too often its "if you don't agree 110% you are the "other side' at 110%, and that just isn't true.

The problem is Jo-Jo already has an old IHC gas job. The big gassers are hard to justify to just take to shows. Nice, yes but expensive to insure, feed and register. His K-7 on the other hand, is of a size that you could actually used it for the occasional parts run or something. I have had a gas Fleetstar for a while before I parted it out. Only thing it got used for was a yard goat, spinning trailers around. My K-7 has done much more. I'm not knocking the truck at all, just that few can afford the luxury of a show queen that only goes to shows, takes up a lot of room, and the case of a 549 is expensive to run. Smaller antique truck can give about the same thrill and is easier on the wallet. It likely why so few of the bigger one survive. Other dog found it didn't fit him all that well either. There is a guy on another site that has one as a grain/farm truck. A little more options there to put it to use.

I hate doing burn jobs. Best thing I can recommend is finding a complete used truck that is similar and making one from the two. Even if you can find a "new" or even used cab, there will be so much other damage that will send you chasing after individual parts, it will drive to cost and time way up. Another complete truck that you pick all the small parts off of, make the job more attractive. Best of luck

Well if it goes into 2nd fine at a stop, that pretty much rules out clutch issues. Remember we can only comment based on what you tell us, only your eyes and fingers on the truck. Could be interlock issue in the shift tower.

I could be wrong. Just something to consider. My reasoning is thus: If there is drag trying to turn the input shaft, it is going to continue to load the gears/dog clutch, making them hard to separate. It is by no means definite, but if it goes into 1st grinding , it would point to drag on the input preventing it from coming to a stop. When shifting in to higher gears, both shaft are in motion the whole time (unless you are trying to put in 3 rd or 4th while standing still). Torque gets multiplied the most in 1st gear, meaning any input drag is multiplied by the 1st gear ratio. It would see a greater force then higher gears on the sliding (dog) clutch.

Does it grind or have any trouble going IN to 1st at a stand still? I am thinking about a defective pilot bearing here.

O/D load violations can be staggering. If they can find a reason to "invalidate" a permit, fines go back to legal limits. Not for the faint of heart.

I remember back in late 2007-2008 being in Idaho, filling my tank and getting a little cash and writing a check for 1 large. Clerk looked at me and said 'If the bounces it is a felony". Yeah, we've been there before, and it was right before a fall.

Neom: It is very simple, she went from being an asset in his eyes to a liability. I have no idea if he knew about the ad campaign and its costs before hand or not. He didn't care about the mess in MN or the citizens being killed or hurt. But make him look bad with a multi million dollar ad campaign and YOU are going to take the fall, not him. Waste fraud and abuse is in the spotlight, and you are going to take the fall. It wasn't Dem outrage that cause her to loose her job it was Rep outrage that did.

My understand, again I am open to correction, is the additive is a "salt" that plates the surface and is blown off the surface by cavitation only to be replated again. You see this "salt" as a white powdery substance on the liners, and anywhere where coolant has leaked and dried. Modern waterpumps use sealed ball bearings in a cavity that is protected from coolant by the face seal and weep hole (to drain any coolant that gets by the seal). I also know it is possible to "over treat" (and there are test strips to check for levels) and cause problems.

My understanding of coolant additives is they deposit a "sacrificial" layer that the cavitation bubble can act on, then it replaced by a new layer, saving the liner from damage. Filters remove any contaminates from the coolant. As the additive gets "used up" new additive must be added at intervals to maintain protection. It can be done by a "charged" coolant filter or in liquid form. That is how I understand how it works. I will say, taking apart an engine with a coolant filter and additive that has been maintained, compared to one that just ran coolant, you can really see the difference. I have added filters to my antique truck engines and see results in how well they cool. It takes a bit to "clean up" a dirty system, but short of pulling the engine apart, removing core plugs and hot tanking, it is the next best thing.

S2130 is a high tower "kit" (full assembly).

Here is the catalog: Levers-ControlsHD eaton.pdf

I have, but not with a 13 or 18 but there is no reason they couldn't be used. Vemeer uses a big Cat with a (I think) 9 speed Eaton on the rear to drive large "mud pumps" for horizontal drills. I guess it is cheaper and more compact than building a purpose built gear reduction on the rear of the Cat. I think it all depends on the output speed desired. The units I saw were brand new at the factory. IIRC it only used one gear and neutral as well as the automotive style clutch. It has been a few years but my memory is that it a plate over the shift rod that prevented it from being placed in other gears other than one it was supposed to be used.

Ill have to look for it, but somewhere I have Eaton shift tower catalog (pdf). Yes, they did make different towers which is not the same as different shift rods. The towers have a "spud" where the isolator and rod are attached.

I hope @kt_Engineer will be able to enlighten us. One thing about learning something, the more you learn the more question you think of.

Ok it sounds like I at least have a handle on the basics. One question that other have brought up: Does this same thing happen to non lined or dry lined blocks? Is the casting attacked by the same phenomenon? I realize we would be unlikely to see the results unless a boriscope is used inside the block. Or does the fact that it is cast as one mean that the walls don't resonate the same way a wet liner would? If I had to guess I would say no, Wetliners are sealed at the bottom by rubber seals so can vibrate, where as parent bore and dry lined blocks are cast as one. However I am just guessing.

Makes me wonder, how many drivers outside of vocational uses have ever driven a truck OTR with spring ride? Good spring is better than bad air!

Not yet, the 5th is off the frame, and I am going to paint where I blasted the rust off with a scaler, then re assemble and sell. To be fair it is going to need some work, and I don't know how many would be willing to put in the work.

The beauty of air ride is you can add lift axles and have the equalize simply, something that can't easily be done with spring suspensions. Company I worked for had ARD's on their heavy haul trucks. Can't say it did better or worse than the IHC (HAS) I had on mine. I had a Neway lift axle and it would equalize after a fashion with the IHC when loaded.

Look at the Maxilite and count the bushings, 4 per axle, then look at the 8 bag and count the pivot points and bushings.

Yeah the ARD is a totally different beast, nothing crosses between those and the ARDAB. I actually bought a nice lightly used walking beam cut off to replace the ARDAB with. Never got around to doing the swap, and it will now be up to the next owner what they want to put under it.
