Popular Post 1961H67 Posted August 20, 2022 Author Popular Post Share Posted August 20, 2022 Worked on the dash some today,I’m still looking for a air PSI gauge and Fuel//Amp gauge if anyone has ideas, going to use them for now, they work but numbers and letters are coming off , still making progress. 8 Quote Link to comment Share on other sites More sharing options...
mattb73lt Posted August 20, 2022 Share Posted August 20, 2022 A thought would be to reach out to Matt Pfahl. He does a lot of vintage Macks and has a lot of resources to get things rebuilt to original. Classic Instruments is another resource that rebuilds old instruments and can also put modern innards into them for those that want the original look but modern operation, like 12 volts. 2 Quote Link to comment Share on other sites More sharing options...
mattb73lt Posted August 20, 2022 Share Posted August 20, 2022 Classic can silk screen the gage faces, too. They could rebuild your originals to match those really nice NOS gauges you found. Also re-calibrate for accurate readings. Quote Link to comment Share on other sites More sharing options...
mattb73lt Posted August 20, 2022 Share Posted August 20, 2022 Hemming's Motor News site, look under Services. Lots of rebuilders there offering all kinds of things. You may find a resource near you. Quote Link to comment Share on other sites More sharing options...
1961H67 Posted August 20, 2022 Author Share Posted August 20, 2022 Thank you, I’ll check them out, I have a extra fuel/amp gauge and air gauge,, I could go ahead and wire everything up, then swap later. Quote Link to comment Share on other sites More sharing options...
Popular Post 1961H67 Posted September 2, 2022 Author Popular Post Share Posted September 2, 2022 Hopefully I’ll get some time over the weekend to get back on my dash wiring, ( No Harness at all, was all trash) I’m trying to use as many old switch’s as I can, sense I’m putting it back for the same look it had when I started driving it when I was 18 . The biggest changes I made are Tubeless tires, Alternator, backdrop manifold and Jake Brake. Tom Mahoney is sending me 2 old style Jake Dash switch’s. Hopefully I can get a good start on the wiring, Equipment hauling has been busy ( which is great,, when buying Paint and old Mack parts) 4 Quote Link to comment Share on other sites More sharing options...
mattb73lt Posted September 2, 2022 Share Posted September 2, 2022 If you can get a schematic diagram, that would be helpful. All the wiring supplies are available that you would need, like fabric covered wires and loom wrap for a period looking harness. Or you could just use modern wire. Then just sourcing the correct gauge wire, most of it will be 14 Ga. and 10 gauge for heavier leads, like off the alternator on the charging circuit. Do you still have the old harness? Even if trashed, it could be useful as a pattern. Quote Link to comment Share on other sites More sharing options...
1961H67 Posted September 2, 2022 Author Share Posted September 2, 2022 I was wondering where I could get a diagram, l looked at some pictures of your dash that you posted and the LJ has fewer wires then the B73 , the old harness is long gone, I do have a parts truck that I removed the dash and it will be a good reference, but I would like to have a factory LJ wiring diagram just to keep it as close as possible. I’ll use modern wire and loom because I already bought enough 14 & 10 gauge wiring. Removing the voltage regulator, generator, and the series parallel switch cut a lot of wiring out already. Thank you. Quote Link to comment Share on other sites More sharing options...
Brocky Posted September 2, 2022 Share Posted September 2, 2022 H67, Are you going to find time to bring a truck down to Dacusville tomorrow????

mattb73lt Posted September 3, 2022 Share Posted September 3, 2022 I wonder if the Mack museum could help with an LJ schematic? That might be worth a call and maybe get the build sheet, too? Quote Link to comment Share on other sites More sharing options...
1961H67 Posted September 3, 2022 Author Share Posted September 3, 2022 I’m going to try to send them a message,, I tried calling a couple months ago and they were still closed. The sent me a Parts build sheet about 10 years ago on it that a lot of the part numbers still change over,, very helpful! I also always wondered if they made a schematic on the air line plumbing? Hopefully I can get in touch with them. 1 Quote Link to comment Share on other sites More sharing options...
mattb73lt Posted September 4, 2022 Share Posted September 4, 2022 I’ve been using a schematic, both air and electric from a B42 maintenance manual. It shows parts for both a straight truck and tractor. The electrical and air circuits are roughly the same for a gas or diesel truck. My air system was completely botched up and had way too many things that I wouldn’t need for my build. So I basically copied how my B42 was done, it’s really just a slightly larger version. Same with the electrics, then I just modified it for the alternator. I’ll try to take a picture of them for you, but don’t know if the resolution would be good enough. I would think if you could locate an LJ/LT manual, with air brakes, that would work, too? Quote Link to comment Share on other sites More sharing options...
1961H67 Posted September 4, 2022 Author Share Posted September 4, 2022 Thank you, sounds great,, Hopefully someone will read our discussion and have a Idea where I could find a LJ / LT manual . It’s the same way on this truck as the wiring and some air lines were cobbled up ,, I imagine a lot of emergency repair on the side of the road,,, Funny part is I remember doing some of them! I ran this truck down I 40 a bunch between Asheville NC and Knoxville TN ( pretty desolate back then) towing for McLean Trucking back to Winston Salem , so I’ve done a few midnight wiring “ Bypass “ repairs .

Popular Post 1961H67 Posted September 4, 2022 Author Popular Post Share Posted September 4, 2022 I actually sent this in to the truck magazine, I worked for Mr Jones, I was his only driver for 3 years. He’s the one that bought the truck from the welding company in 69 , it was still the original colors but faded bad, I tapped it up one Saturday and sprayed it with some left over paint I had painted my race car with. I got the truck from him in about 1982 . I still have the magazine . 4 1 Quote Link to comment Share on other sites More sharing options...
