mechohaulic Posted August 16, 2023 Share Posted August 16, 2023 is there a possibility the cab was changed without changing door vin tag?? i could understand a twin being converted to a single. unless it was a long wheelbase single originally then tandems installed . does the door tag match the frame serial number ? seems a little investigating is called for. different paint color ?? do the frame rails look "tampered with"? cab change seems my vote , 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/11/#findComment-537073 Share on other sites More sharing options...

mechohaulic Posted August 16, 2023 Share Posted August 16, 2023 picture of right front shows red painted bumper/ cab . under cab definite line taped off separating red from black frame. possibly why the turquoise paint on rears. hopefully a vin on frame rail will be different then door and an easier chance to acquire parts more accurately.

Joey Mack Posted August 16, 2023 Share Posted August 16, 2023 I saw the picture of the rear frame. I didnt see a seam or joint where the frame was stretched.. Maybe Bob can take a look for a seam, and also look on the frame for the VIN. Mech, The VIN is on the right front frame rail, right? I know on newer trucks it is, but I cant remember on the 70's models.

mechohaulic Posted August 16, 2023 Share Posted August 16, 2023 since the frame vin matches the door. i'd say it was a misinterpretation of model/ serial number reading. a DM607 S could have been taken as a single axle by memory. actually a single axle is a T , DM world a S would come under light weight DM vs a DM----SX ; heavy weight .

mowerman Posted August 16, 2023 Author Share Posted August 16, 2023 OK, thanks for that so it looks like somebody change the rear end for some reason you think they would’ve use something with some tall gears instead of this farm tractor rear end but then they probably got them pretty right and being a dump truck. It probably didn’t go very far. Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/11/#findComment-537101 Share on other sites More sharing options...
Joey Mack Posted August 16, 2023 Share Posted August 16, 2023 when you clean the spot on the front really good, you will see the ratio is stamped into the housing.. just in case you wanted to know.

mowerman Posted August 16, 2023 Author Share Posted August 16, 2023 Thanks I broke all three screws on one of the hood latch catches. I knew it was going to happen. I got disgusted and one in the house ha ha plenty of time for that thing. I have to go back to work tomorrow so I think I’ll just use the rest of the day to relax, thanks for that Quote Link to comment https://www.bigmacktrucks.com/topic/73081-finally-some-dm-progress/page/11/#findComment-537103 Share on other sites More sharing options...

Yes, "T" would be a tractor. "P" would be a platform (straight truck). Not many "P" trucks around, from what I have seen. Mostly tractors. An "S" would definitely be a tandem. An "ST" would always be a tandem-axle tractor. An "S" could be attached to either "P" or "T", I suppose. But I don't know if I ever saw an "SP". "X" was heavy-duty. "SX" would be a heavy-duty tandem-axle. They used that same nomenclature through a lot of the models. B, F, R, U, DM, just to name a few. Another elegant system Mack used, that Volvo never gave a rat's rear about. Quote "Eagles may soar, but weasels don't get sucked into jet engines."

mowerman Posted August 16, 2023 Author Share Posted August 16, 2023 I’m surprised they’re still making them look half decent instead of turning them into some aerodynamic garbage like everybody else has….

doubleclutchinweasel Posted August 16, 2023 Share Posted August 16, 2023 Actually, I just found a brochure in my list showing an "R700S" tandem-axle truck that was not an "R700ST" tandem-axle tractor. So, they must have just decided not to use the "P" in some applications. That brochure was a 1972. But, I found other brochures as late as 1976 that still listed certain models as "P"s. 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

doubleclutchinweasel Posted August 16, 2023 Share Posted August 16, 2023 I have these (very) rough scans of a bunch of the old brochures. I would love to screenshot as many of them as I can and post them on here somewhere. Maybe in the wiki section? Some would be hard to read, but on some you can make out the different engines between different models, and you can always see the number of axles! What does anybody think???? Here's a sample (1965, I believe). Quote "Eagles may soar, but weasels don't get sucked into jet engines."
