I worked at a shoe company in the 80's and we were still running trailers with no maxis. We had a few roll away from the dock because the spotter got lazy and didn't chock the wheels (air leak = no brakes).

I'm no expert on the subject but from what I can tell my hubs are 2 inches bigger than 11rx24.5 rims. How old are your tires and how much are you asking?

You're right...your hubs are 24" in diameter, 24.5" tubeless are 22" diameter. The tires are 24.5" inner diameter but they have a flange on the rim that reduces them to 22" hubs.

What engine do you have?

back in the day; 5th wheels were mounted with only long u-bolts ; way too much movement. most all wheels mounted later were bolted to their own  plates which were bolted to angle iron bolted through the frame rails not the frame flange . as stated earlier, with out the main frame plate  on the 5th wheel too much flex would be on the chassis. of the 50-60 + 5th wheels i mounted while at Mack none were direct mount to the frame. all were either welded to angle iron   bolted to the frame (sliders) or bolted to the iron that was bolted to frame (fixed).

I've seen a bunch of trucks with u-bolt mounting that had blocks of steel welded to the frame rail flange to keep the thing from moving back and forth. Of course, they shouldn't be welding on that flange.

24 years ago this weekend I found this truck in Litchfield, CT. Dragged it home and dropped it in front of my barn at the house I bought about a year and a half beforehand. Lots of things have transpired since that time, but one of the good things is seeing this truck, nearing completion, sitting in the same exact spot.

It's funny...the cab doesn't look that bad in the "before" photo but I know you had to cut out a lot of rust and damage to rebuild it. Same way with my truck, bondo covered many sins.

In Australia the angles have sit proud of the flange so there is 1/8 gap between the plate and the chassis rail flange

Would be a shame if the same rules applied over there and you had to bugger up the paint work

Great stuff and a very detailed video

So they don't want the fifth wheel sitting directly on the frame rail? I wonder why that is.

Or does his email need a k in it???? Mack truck nut??

Good question...I don't know.

Phone 813-777-2961, email mactrucknut@aol.com .

The guys at Rome are top shelf...they hooked me up with everything I needed for my truck at very good prices.

Thanks.Oddly,when removing,a 15/16 wrench on the flats was too small,a 1" was too big,a 23mm fit perfectly.Would there be  a metric  version of these fittings?

When they make pipe fittings, they don't size the hex to a certain wrench...they figure you will use a pipe wrench or crescent anyway.

Those are definitely rare, but that one's pretty rusty for $18,000. I've never seen a fifth wheel that has ears that rest on the frame rails like that.

Judging by the photos, it looks like a nice truck. Too bad it's not a twin screw.

You hit the motherlode of NOS parts! It's really looking good.

I see the poster that asked this question never came back . But I wanted to help shed a little more light on it for you . 

The first number 6 you got right . The 59 is the engine code . From my list from BMT , its a Cummins NHRS6B/320 . I honestly don't know what that is ,lol . Hopefully you can help in that department . 

You got everything else right , as far as I know . The ST at the end of the number means a little more than twin screw . The "S" means twin screw . The "T" means it was built to be a tractor . 

A guy named "Cam" on the ATHS forum says that the NHRS6B is a supercharged 743 cid engine, but supposedly they quit putting them in trucks in the '60s so maybe not the right engine code for this truck. If it's a '79 it should have an 855 Cummins.

I started looking things over to see if it will run and found the intake pipe missing a clamp, allowed rain water to go into the turbo. Fortunately the shaft still spins free, but I want to pull the housing off to see what is lurking inside. A great example of something simple like a clamp causing bigger problems. The engine tag says it's a 335.

I can't even remember the last time I saw a truck that old running up and down the road making money. I wish I saw more of them!

One fine looking truck!

I was back up there and snapped a couple of engine photos.

To find my wheel seals, I went online and you can look at an SKF (CR) wheel seal catalog, they have dimensions in there so you can measure your old seal and match it up. Once you get the SKF number you can cross it over to whatever brand you want.

Wikipedia says, "In 1940 the US Army ordered 700 Mack 4 x 4 truck tractors, intended to tow pontoon-carrying semi-trailers. 694 were delivered in 1941 and the last 6 in 1942. An Autocar design was standardized by the US Army and only 700 NJUs were built." Since this is a '41, it could be ex-WWII Army truck.

Something you don't see every day. It's in Taylorsville KY, asking $5,500.
