They say it’s a small world. that power line was the last clearing job I got to work with my dad before he died. Have lots of memories about that one.

Looks like this truck (from the Mahan collection) has been the subject of a conversation here before. Look about half-way down, where B66 is helping with the serial number.

Weaubleau! You're just about 35-40 miles south of Warsaw. Spent one hot-ass summer in Warsaw in '79, clearing a power line RoW from the site of the Truman Dam to a substation in Clinton. They were still calling it the "Kaysinger" dam at the time, because of the location.

Mine was changed when I got it. Like everybody said, it had a 1-wire alternator with integral regulator. Battery cables swapped to keep the starter running the right direction. The only issue was the amp meter. It was a single stud type and was grounded through the body to the dash. I swapped in a 2-stud model so I could reverse the polarity. As far as I know, that was it. All the lights worked. The fuel gauge didn't work, but i had a hardwood dowel "dipstick" under the seat! I agree with Paul and Larry...just reverse the polarity on the truck and be done with it. Not that difficult.

I thought that was it. 1967 DM865SX

I am pretty sure that tractor (or one like it) is in my "Mack: Driven for a Century" book. Think it says "Big Snort", or something like that, on the hood. Will look that up tonight.

There are enough guys on here to help you do pretty much ANYTHING. I doubt there is too much that SOMEBODY here has not already done.

You're correct, 'Train. I had not considered LED bulbs. I should have said INCANDESCENT bulbs do not care about polarity.

Light bulbs typically do not care which way the current is flowing. Not sure the electric brakes would either. Somebody on here probably has more experience with that than I do, though. My R was converted to negative ground when I got it. Basically went to an alternator, and swapped a couple of cables. All the lights worked fine. I had to change the ammeter to 2 "two post" model so I could reverse the polarity on it. I'm sure some honest-to-goodness experts will chime in here and help you out...especially if you add pictures!!! We love pictures!!!

We do some 3D printing here (resin). But, we do not have the scanning capability. Should be companies out there that do both. A quick Google search should show some in your area. For a usable emblem, I would suggest the metal media (SLM, DMLS), not the resin (plastic). The metal can be polished or maybe chromed. The printed item can be made of varying densities, from "skeleton" to "solid". The metal parts lend themselves well to varying densities, with skeletonized areas where possible and solid areas where needed.

Nice thing about the old Macks; you could fix a lot of things using stuff from the local hardware store.

God, that sound takes me back! Thanks for posting that.

That looks like one of the galvanized cabs, so you should be fortunate there. There seem to be more good engines and parts out there than there are good cabs any more! Best of luck to you.

Joey Mack is a great source of information on those "later" models. There were another one or two who were good also, but I can;t recall the names right now.

There are a couple of Mack techs on here that continually blow me away with their knowledge on these things. They should be of great help to you.

Pictures. We love pictures!

No, the "early" box would not have been available. Not even sure about the "late" box! Just trying to figure out if a truck of that vintage could have had the OD set in the compound. I never saw one that did. But, like I said, I learn something on here every day.

Awesome!

For what it's worth, I love the tall pipe on top of the canister. Lots of our R600s had that (like the one in my profile pic). Think it was pretty common on the Thermodyne engines (like my R611). They were originally oil-bath cleaners. Mine still was. Most of the ones we had back then had been converted to a replaceable paper element. It was a Mack kit they used to sell. When I had mine, I tried with no luck to find that old kit. Would have loved to have replaced mine. When we got our first Maxidyne truck, it had the short pipe on top. Little squatty thing. Not sure if that was a Maxi/Thermo difference, or if it just happened to be the right year model. Or, maybe it was a paper filter setup already. Do not remember. But, I do remember the one I spent most of my time in having the "oil bath" canister, but with the paper filter inside it. Was kind of a nice surprise the first time I pulled the bottom off of it and DIDN'T get oil all over me! I have also seen many a Mack with a plain black aftermarket canister on them. I think it's a Donaldson item. Looked something like this. Maybe you can adapt something like that.

If a straight drive transmission is an "anti-theft device" for new drivers, then a Quad would have to be like Kryptonite! Actually, a Quad should qualify for a lower insurance premium, since nobody could steal the blasted thing!

Story of my life: a day late and a dollar short!

Different years? Gas vs. diesel?

Correct. The "later" ones are the ones I was more familiar with, where the REV was in the compound box. I don't think I ever saw the "early" one in person.
