Why would you want to do anything to one of those ? In my opinion, one of those engines in good shape doesn't need much . Once you accept that you're going to get passed going uphill, cups now and then and the occasional replacement of the harness. They were an oddball, but none the less a good engine.

Wasn't that a white one set up for a Caterpillar ? They have lots of trucks there with potential.

Yep, I was wrong. It's actually in the pictures of a heavy spec Mack dump truck (ten wheeler)

Maybe when I was on their website looking at the gliders I saw it by another truck . (sorry) But there's a blue RW there at the place. They have lots of Macks there. Looks like a few decent LTs too. Interesting site to review.

No..... I didn't even notice that one. That place where the gliders are has a blue Superliner with stripes and air cleaners. Looks like a big spec tractor and maybe even an E9. That's not to say I don't love that orange one in your picture

I was looking at the add on my laptop .....what a nice R model. The inside is really in good shape too.😍

How about the RW in the background ???

That's Mack taper leaf . Some refer to it as " underslung " that's a beautiful R model

You think I'm kidding, you and Lovey at TR ..... I think it's a good idea

Don't eat the dog , I'll send you a gift certificate for Texas roadhouse

Not many guys on here haven't been through the same thing or something very close to it . Very easy to get tripped up when working on that. Bet it'll be the last time like all the rest of us who've done it.... myself included

I'm finding out that on some newer trucks, this is even the case on certain drivelines. More important than ever to mark stuff before disassembly , and mark in a lasting non aggressive way like electric pencil that isn't bash'n it with a punch and won't wash off or fall off during moving it.

I'd imagine when you use it, it will be with the same attitude as when you' work on it. It'll go a long way like that.

See ? That truck has the whole Australian look going on.

Superliner had clamps on the legs, whole different stand.

There's a lot of different ways to repair this depending how bad it is. Springs ?? well, a spring doesn't need to be broken to be shot. The three on the bottom (mains) can have their round hole worn egg shaped. That's the hole the rubber pad's dowel goes in. If it's worn, spring is junk. The buckets ( end caps the pads go in over time can rot away and don't squish the pads like they should . Then there's the trunion bar. It could be worn the saddles ?? the bronze bushing could be replaced and new thrust washers and seals . That's if they aren' t worn way beyond what they should be. Then there's torque rods that are likely wiped out if the other components are compromised . Then the grand daddy off it all is if the trunion stand (complete assembly containing the bar) needs to be changed. Often it goes along with the bar. In some cases the trunion stand may be rotted and you may not realize until it's inspected by someone who knows where to look. There's an aftermarket trunion stand that saves a ton of work replacing one in a dump truck, but they're not free and are somewhat heavier than the Mack trunion stand. Without seeing it in person ? hard to say how involved you're going to be. IDK if guys are still changing just bars in the 600 series anymore. Used to be an interesting process with dry ice and a pretty robust mobile press.

God you do nice work.... holy cow. That truck is gonna look better than new. Between what you're doing and the materials available compared to when it was new, it literally is coming out better than new.😍

I believe once the chassis is secured up the first thing is slice through the center of the bar between the legs. If the bar tweeks at all from centered , game over. Need a trunion stand. Lots of cutting with a torch . If I remember. the legs were heated where the bar went through and the bar was put in dry ice then when it was time to get it in, you had to know what you were doing and press it in to the desired measurement . Guy used to have a stubby press that the ram was like 9 inches wide or something like that. ( it was the same one he used to use on the spindles on the 44s )

Glad I'm not the only one who had thoughts about that post tjc...... but I'd likely be thrown off the site if I responded .

You sorta need to know what you're looking at to determine how extensive a repair would be needed. There's a lot that can be worn on the suspension and when it's all worn ? then there's lots of movement . Replacing a trunion stand is a huge job on a dump truck, even for a regular spring shop. You need to find a place familiar with Macks who could be honest with you about what needs to be replaced. (lol) lots of guys like to think the rubber pads at the end of the springs cure everything. Maybe a new torque rod too, cause they're the cheapest component.....it's usually not the rubber pads or as simple as a torque rod . Just say'n. Worst case the repair easily reach 5 figures on a dump truck.

Your four headlight Macks somehow look correct on your trucks. They're not like our four headlight industry standard ....are they ?

How about when guys would put the headlights from an Eldorado or Toranado ( when they were front wheel drive at first ) I remember that too. I like one big round like they're supposed to be

That's someone's R Model toy (lol) Old R with a 673 (?) somebody was quite fond of. Looks to be other Macks in the background , it's easy to get the fever that fella had .

The corruption amongst those in power is sickening. Look on the bright side, when oil companies make enough off all this to pay more to get their way ??? All the " green " BS will calm down for a while.
