B-73 Restoration
mattb73lt replied to mattb73lt's topic in Antique and Classic Mack Trucks General Discussion
I bought it from Doug Fetterly about 16+ years ago. He makes and markets repro steel and stainless B model bumpers. -

No, I bought it years ago. Just machined the footsteps and mounting holes from the remnants of the original. Took a little ingenuity to support it while working on it. Then I rebuffed it. -

Primed all the repaired parts, cross members and mounts for the frame and driveline. I'll store them until I'm ready to start assembly. Due to much improved working hours, this truck could be back on the road in shorter time. -

Hopefully, It will. After I repair the lower cab and a few other areas, I'll start repairing the panels one by one. Then start the reinstallation. Just going to worry about it one panel/repair at a time. It's kind of daunting looking at it as a whole. This is the worst part of the whole restoration. -

Back at it again. I've had some consistent time to devote and have gotten a lot accomplished. I had all the aluminum frame castings repaired where needed. Then I machined all the repairs and replaced all the holes on the Bridgeport. While I was doing that work, I made up a polished stainless bumper to replace the mangled aluminum one. Finally, welded in about 60' of 1" square tubing to brace it as a removed the final panels for repair. -

I think I might go that route, I like that you can paint overt it. -

Hopefully! I will have to have some small parts fabricated locally, but I have all the major pieces. -

I've collected up numerous pieces that are re-production (sills, cab back) and a lot of donor pieces. I was lucky enough to have a friend give me a Bridgeport, Ct fire truck cab. It was really gone on the bottom end but all the upper metal was good. I carefully cut it apart and was able to get the cab top, under structure for it, cowl and windshield area. -

I was going to use Lizard skin on the entire bottom, then Dynamat over the entire interior. Probably go double thick under the mat for the firewall. -

It’s going to get a lot worse, soon. I need to cross brace everything first before going further. The roof is coming off and the lower cab sills will get replaced. I don’t think the L cab is as sturdy as the standard B cab and more prone to rust. The back panels on this one were replaced early in its life and weren’t done well so they came off easily. This is certainly the worst part of this project and it’ll take a bunch of time to fix. -

Steam cleaned the crap out of the cab today. Amazing the amount of dirt and grease that came out of it!! Spent three hours on it once it got set up this morning. It's squeaky clean now and ready for more work -

Tracked down a really nice backdrop manifold last year, after putting out some feelers for one. Scored one that didn't break the bank and was in excellent condition. Now to get it in and hear it run!' -
Steel spring hangers should directly replace the aluminum ones. My B-73LT had a mix of both types on it when I got it.

Matt Pfahl was kind enough to bring my frame to my house when he was in the area making another delivery Sunday morning. With the stretch it won't fit on my truck any more and I don't have good enough tires to tow it home. Progress should pick back up now that it's back. -
Help Identifying B Model Dash Switch

No, no, no, those are the tanks for the Chem Trail Solution now used by airliners in a secret government program. -
Help Identifying B Model Dash Switch
mattb73lt replied to 58GreenMackB's topic in Exterior, Cab, Accessories and Detailing
It might be for a Fuel tank indicator switch. My B-42 had one in that spot to switch the sender indication from Left, Right and Aux. I left it in place and put new senders in each tank to check them while running, since it was all there and wired for it. I re-plumbed the tanks and deleted the separate floor valve when I converted it to diesel. -

Good guess!! Just threw a tape on it today, looks like right around 249". It's getting a 24' Jerr-Dan rollback equipment body. -
673 NA covert to turbo
mattb73lt replied to Carl M's topic in Antique and Classic Mack Trucks General Discussion
That's what I did when I swapped over my B-42 to diesel. I was able to get a B-61SX from behind the cab forward, it had everything but the motor. Everything bolted right in, front cross member, transmission mounts, etc. There's a lot that you'll need that you'll have to scrounge for to get it done right (Shutters, brackets, air lines). The good thing is, the frame is predrilled for both mounts(Gas and Diesel). It was actually a very easy swap to bolt right in. I started off with a 1957 END-673 for ten years and after having a major issue with it a 1973 ENDT-675 (237) since 2011. Miss the bark of the 673, but love the power of the 237. -

Yes, there's a cast divider separating the cylinders. Three upfront and three to the rear. The gasses meet as they enter the exhaust pipe. I've been told that's where the exhaust note comes from. -

Hope all is well with everyone that's following this. Hasn't been since August since I last posted. The project was on hold and stored at Matt Pfahl's since then, while I waited for him to have some floor space for me, and I ran my own train off the tracks after picking up a '26 Ford Roadster. But, back on it today and completed the the frame stretch by joining both frames together. Long day, but it's done and straight. Went as planned and without a hitch. The bare frame looks looonnng with it joined up.
