Now that you pointed it out, it looks like the fender is taller. Note the hood latch as well seems the Australian trucks often have the cab higher from the frame and then something done with the hood to accommodate that 🤔 whatever it is, that's a pretty good looking Superliner

Good clamps and spacers, they stay put. Don't see many around here. I'd guess in Australia the weather is much more favorable to chrome on trucks.

Funny you ask, no. Those were just regular 12 and a quarters. I did have beauty rings on them at one time. That truck in the avatar was inspired by another RW from Canada that had chrome 8.25X24.5s on it and aluminum budds on the steer. His was an awesome truck, he put a ton of money in it and it looked great...and he used it. He swapped the 44s out for 58s and had the chrome rims on it. I didn't have pockets as deep (lol)

They're probably 9 inch rims

Pretty common issue with those harnesses. On the bright side ???? likely avoiding some other harness related issue that wasn't too far away from showing up.

P A I

I've seen adds for a different kind of bushing. EtCon ??? or something like that. I've often wondered if they would be better than plastic. I almost think they don't require grease either...... not many of those free magazines come anymore, used to see them in the back pages.

Chrome rims 😍

Sounds like an engine brake problem, which could be something simple or a serious problem . Good move walking away from him not wanting to make it right.

Hey !!!!! we take our laundry pretty serious around here

(lol) like everyone else, I went to their site and looked at it. All depends how much they want for it. Just a guess, but I think that truck has a fair amount of work left in it.

On an old truck like that ?? miles are probably correct. That truck wasn't made to go millions of miles. Just not the nature of a construction truck. Hours mean more to one of those. Above and beyond all ??? if it was taken care of is what really matters. Those trucks like in that add were a very good truck for what they were made for, and that one likely still has some life left in it. I didn't see anything confirming that one is even a dump truck ??

FYI.... that add ? that's a real dump truck spec. Maybe not the most glamourous , but way better than a converted tractor if it's in any kind of shape and not abused or neglected

R.E.D. is 100% on this. No offence, but even thinking about try'n this repair armed with a 1/2" impact ??? It's outta your league, and not out of the question someone can end up hurt. Right now, this problem can still be cured with a blank check. Crushed by the truck, or wrecked ??? not as easy to make go away.

I think the B53 guy was try'n out that 379 ???

Judging by that tag on the rear ? It's not a Mack reman , early failure of those isn't uncommon. Those plugs you mentioned up on the power divider and side cover for the bevel gear will need to be filled when you replace the carrier. The power divider.... you'll put a couple squirts in and it'll be running out, but it has to be filled in there. Then the other plug on the side cover and the bottom plug on the housing, all need to be filled. Then if nothing leaks ?? a check in the plug in the housing will be it .

Leaf springs are supposed to be able to slide over each other as they flex. Those springs and bushings are just worn out. Sounds like you don't have big enough tools to make that repair. R.E.D. is right

😍

You can actually see the bushing out of center in that one picture and the leafs are worn into one another. Time for some new springs and you'll need someone to either find you the heaviest to fit the chassis or add to it like someone already did. They're only rubber bushings and not very good at taking the pounding greaseable pins and bushings will .

That's a twelve thousand pound axle and suspension someone seems to have added a extra leaf to. It'll sit up a little better, but everything was engineered for 12000 pounds. So it's bushings probably are shot from being overloaded.

What he has is called a cobbled little taper leaf some brain surgeon thinks is better that way to put more weight on on his basic 12000 pound steer axle. Guys do it, it kinda works (I guess) Think on that model truck ? I'd take a look at the cab mounts , that'd explain a clunky noise by his feet.

That looks like an aluminum frame in that truck. Be interesting to see some more of that Mack

Who's that guy standing by the B53 ? Something almost looks familiar about that guy 🤔

On a truck that old ??? Who knows what someone did or didn't do to it over the years. The important thing is you have the stainless steel /teflon discharge line . It really doesn't matter how long it is after a certain length. If you do decide to anchor it to something away from the exhaust (good idea) You'll need those P clamps with the teflon instead of rubber or they'll just melt and wear through your new discharge line. Believe it or not, that discharge line gets pretty hot from the compressed air going through it. Just run it with gradual bends if there's extra discharge line. (like winding it up in a loop is a sure way for it to collect water and freeze)

It'd be braided stainless or copper from the compressor. Then most mack's of that era had a fitting with pipe thread on each end and a mounting hole to anchor it to the transmission. The ss or copper on one side, and usually braided rubber airline with JIC fittings on the other to the wet tank or dryer
