I never realized that they did both the fender extensions and the extended radiator shell to fit that huge Hall-Scott in there. I always thought it was just the radiator shell, but I've never seen one in person or close ups pics of one. Kind've like using B73/75 and B71 parts to fit it in there. I know a Cummins is 6" longer than a Mack engine, so maybe the Hall-Scott is about 12" longer?

Not the easiest swap to do, but it can be done. Main problem, as you're finding out, is availability. Locating a set of hubs, front or rear, can be tough. I left the Dayton hubs on my B42, but swapped the rims to 22.5" on the FA505 axle. I like the look and the B model chrome hubcaps. On my B73 with a FA507 axle, I wanted to put Budd hubs on to run Alcoa rims because it has a lot of aluminum and stainless and I wanted that look. It was a whole separate project to do it, with a whole other project to add brake drums to the front hubs as they came off a truck without them. Matching up the the hubs to fit the axle/spindle arrangement can be problematic. It can be very time consuming tracking everything down and making sure it'll all fit.

My best advice would be to be patient and network through everybody you know and sites like this. Be adamant and keep asking everywhere you go about them. Some will surface. As others have stated, you can also work an axle swap to make it happen.

Best to indicate the bell housing you put back on it.  

Oh, I will go through that drill again. Both the bell housing and flywheel!!

It’s straight ( for now) I have room under for a short muffler, I thought I would run it for a bit when I get it on the road and see how annoying it is . I remember you drove yours to the DMV , how did it sound?

Once it get back on the road my plan is to run it for a while, but probably put an under frame muffler or resonator on it to quiet it down a little. The insert in the stack helps, but it's still pretty loud.

That looks really nice. Is it a straight pipe or is there a muffler somewhere?

I think the "Loaner" runs hot!?!?!? Set fire to my mixture of ATF and Marvel Mystery oil heating up the cylinders while trying to un-stick the engine after sitting outside forever. After letting it sit for a few days it popped free allowing me to disassemble more of it.

Waiting...waiting...

Yeah, so am I. Nothing yet from the machine shop. I did harvest a lot of parts out of the "Loaner" 220, though. Lots of Cummins parts laying around the shop. Found a 6" pipe wrench laying in the pan??? I wonder how long that's been in there?

Excellent work!! Looks beautiful.

Pretty soon he's not going to be able to stand up in there like that!! He's getting big.

Here’s another quick video of it running just after I got it hooked up several years ago. It’s in really good shape with little wear on the ways. It still pretty tight, overall.

They ran those off overhead line shafts. Big flat belt from the shaft to the lathe. To reverse it, you’d twist the belt. Have run many of these converted to electric motor. 

Yes, if you look at the video, you’ll see a large pulley in the center of the line shaft with no belt on it. That would be the one for the belt with the twist for reverse rotation. The clutch lever pushes in both directions to engage one or the other drive pulley off the same shaft.  The way this is set up I can only drive in one direction. You need a longer run to make that twist and I don’t have the space to do so.

I'm curious what powered that when it was closer to new. I've seen pictures of facilities with overhead shafts powering several things it looked like ?   106 years old....wow

I've wondered that too, thinking of that time period. Could've been steam, gas, water or electric. I was in a mill once up near Cooperstown, NY. It was a wood shop that was powered by a 20' wide water wheel. When they opened the sluice gates, the waterwheel would fill and start to turn. The whole mill was set up with line shafts and flat belts. You'd pull individual levers near each machine to activate them. Once the water wheel came up to speed the whole building came alive. it was really amazing to witness.

Very nice. Excellent work and a great storage area, too!!

They were both, 6 & 12 volt positive ground. Mine was 12V+ ground, a 1963. My friend has one, but 6V+ ground and a 1956. I think early production was 6 and later was 12, but that’s just what I’ve seen. Check the voltage regulator cover, a flasher or maybe the size of the battery box. Something electrical will be marked with the voltage.

Looking good! I ended up finding same mirrors for my LT, brand new luckily

I believe the mirror heads are still available in stainless along with the the brackets they mount to. The arms to the doors are the hard things to find. I was lucky enough to find a complete set in stainless of reproduction ones. They’re styled after the B model ones and I had to fill and redrill the holes in the doors as they were a different pattern. I still have the original steel ones if you need some? They could be chromed.

I think those are pretty rare. I've only seen a few in pictures plus the one in that movie. Maybe they were early production? The single air motor design in the cowl was a better arrangement, though.
