Air chisel with long bit, then a die grinder to cut through the stainless ring that's inside the brake.  If someone had two in there ?   you might need something to take up space. Remember  the more you turn the adjusting ring on the clutch cover the less holding force you have.

We’re those pictures taken in the highway material pit.Spent plenty of time there when Corson’s owned it doing their stripping.The truck looks great.

I wondered the same thing. If so ??? a fitting location to take pictures of a DePaul truck

The Mack compound boxes did have some of the linkage exposed on top of the transmission.  See the link, below.  One of the pics shows the top pretty well.  The linkage from the compound shifter to the rear (compound) box are exposed.  So, yes, someone may have used a pry bar to move linkage if there was a problem with the shift linkage.

 

 

I forgot all about that

There was one in Truck Paper not too long ago.  New in a crate

Love all the pictures. Thanks

There's several variations of clutches. Basically a 14 inch goes in a flywheel with a (pot) like you have and a fifteen and a half inch goes on a (flat) flywheel .  there's also some different types of locking of the adjustment. Some with the two bolts holding it to the cover are spring loaded and lock in place after turning (like yours) others have the same thing except they're not spring loaded and have a strap that is hexed to go around the adjusting bolt to lock it. then some have an actual locking tab that bolts to the cover and goes between the lugs on the ring in the cover ( there's no picture of one of those here )  Your's ???  I'd be  really surprised if the ring in the cover will turn.  You'll push that adjuster in and it will turn.....but really not turn the ring inside the cover. Remember, this can only be turned if the clutch is disengaged. ( like if it was together, someone would have to hold the clutch in while you turned the adjustment)  In general, any 14 inch clutch will work.  differences are holding force and input shaft size ( inch and 3/4 or 2 inch )  You're gonna go nuts with the clutch you have. Try and find a better one that wasn't as worn out as the one in the pictures. 

That clutch is shot.  The pressure plate may even be shot as well ( like already adjusted to it's limit )  I once helped a guy who replaced a clutch cable in one of those and installed it backwards. The original Mack one goes farther from one direction than from the other. As far as the clutch in the truck, the space between the bearing and the clutch brake  should be around a half inch and not much more. this is done by turning the adjustment on the pressure plate and to do that requires holding the clutch disengaged so it will turn.  Be aware the more it's adjusted (turned) the less holding force the clutch will have.  Looks like maybe time to see about finding a different clutch assembly 

I also kinda wonder why the levers on the pressure plate seem to have a circular mark scratched into them.....hmmm

$ynchro 

You need to find yourself an old 2 inch input shaft that's in good shape to use for lining up those clutches.  It's much easier than using the transmission.  I still think a disc could be backwards.  I'd feel really bad if you took it apart again only to find you had them in correct though.

It's possible the discs are backwards. they only work one way, but will go together backwards

Original owner mod.      It has a belt driven water pump and it’s hook up to the aftercooler.     Has its own water cooling system.   

Ahhhh  I see.   There's a lot to explore on that truck from looking at the pictures.  At some point, that truck was loved

What's the little radiator (?) in front of the radiator ?

i belive the allision is .60 and a mdrive is .78  in other words alot of diffrence  still little shocked about the higher ratios on a dump truck application

I don't understand the super high axles in dump trucks either. Salesmen seem to be under the impression the low gear in the transmission can do it.  In my opinion any of these new engines have over 1000 pound feet of torque right of idle ( @ 1100 or 1200 RPM)  even if feathering the throttle.

What are you looking for? I have a half dozen more BBC's most are 325 to 375 h.p. One 454 w/ZL1 aluminum heads and tri power but that was in my old Monte. All are standard across the board (bore, crank journals and cylinders) All are 1965 to 1970. The rack in the back ground of the engine on the stand has a couple of dozen sets of open chamber BB heads.

The BB for you Vette is the one from my old 55 chevy. 572, 11.6 to 1, AFR heads, 12/71 BDS blower and twin Dominator 1050 cfm  2 barrels set up for a 90/10 blend of Methanol and Benzine. Pinned the  hp/ torque on a 1500 h.p. dyno. pushed my 55 through the traps at 161.7 / 8:338.  Pretty good for a 1962 built gasser with only updates were roll cage and chute .

I don't need anything quite like that (lol)  but I do like the idea of a big block.  Nothing sounds like a good and healthy BBC put'n it to the ground through a 4 speed

Did anyone ever actually indicate the bell housing in this truck who knew what they were doing.  It screams misalignment 

One of those big blocks would be just right for my corvette :-)  maybe not the 454

That spring looks a lot like a spring from the clutch on a Mack with a cable

I used to have one that was pretty close to that.  

I often wonder where these trucks have been hiding and staying so well preserved ......and somehow ??

I missed the point when cab over Freightliners actually became (gulp) COOL   didn't seem that way when they were 

around side by side with new Superliners and such

12/24.5 on 8.25x24.5 budd rim   big as you're going to get without spending  a fortune 

closest to a 11/24 would likely be a 12/24.5 on a ten hole tubeless  Budd wheel  (8.25X24.5), and that's probably still a little shorter than an 11/24.  There's no cheap way to get rubber that big no matter what route you take. Not much point to a big tire on a Budd wheel as stud pilot wheels could never handle the weight a Dayton can at that size, but for a truck used for recreation ???  closest as far as looks

That Davco filter isn't supposed to be full. That's how they show they're in need of replacement .

The higher up you see the fuel, the dirtier the filter is and needs to be changed.
