I am guessing both the trunnion mounts and crossmember are aluminum? I took my trunnion mounts to an old school welding shop and had them welded up. They were not impressed with the quality(or lack of) in Mack's castings. I'm hoping they will hold up for truck show type use but I wouldn't want to use them for hauling any weight. As for the cab crossmember, If it's not too badly broken it can also be welded. About 5 years ago I had a couple of new aluminum crossmembers cast. All spoken for now but if you needed one I can check into what it would cost in todays dollars. Was about $1100/copy the last time. I didn't have an aluminum crossmember for my LTL so repair wasn't an option.

The LT's I've seen have had the serial number stamped in the RH (passenger side in the USA) frame rail either above the front axle or near the rear spring hanger for the rear suspension. I've seen them both places. Also seem trucks that didn't have one at all.

that is a gorgeous Mack!! Great job!

I've used the mig welder technique many times on Ford FE engines. Had very good luck getting the stud out without drilling. Takes 5-6 tries sometimes. Keep building it up until you can get a pair of vice grips on it then start gently putting pressure back and forth.

I've got a B61 front axle the stud pilot budd hubs and drums. No backing plates. They are in CA though. Long way from PA.

Thanks! This one was repainted to match several trucks we've had over the years. Started as a lowbed truck for OC Jones, a contractor here in California. It was green from the factory.

I like the bottom one better as well. Top one is what's on there currently.

There is a difference in the fender height on early RL/RS700 western hoods vs late. Top picture shows the later hood. There's about 6" between the white stripe and the top of the fender. Bottom picture shows the early hood where the white stripe is right above the fender. Same truck before after the hood was damaged and replaced. Wish I had known then, I would have fixed the early high fendered hood!

Not sure about the DE but looking through the complete LT chassis register Mack seemed to do whatever they wanted with chassis numbers. There are sections of anywhere from 1 to 20 chassis numbers that didn't get used many times over for the LT's. Not sure how they assigned them but it wasn't as they came off the line. Some of them are not even in chronological order. Very likely that the highest chassis number for the DE is well above 3176. The only thing Mack seemed to be consistently good at was inconsistency.

We're working on that! Pan needs to come off as there are some rust holes in the bottom due to condensation(I hope). Oil looks good it it and not overfull. Fingers crossed.

At this point just a preservation. It is really complete so if we can get it running it should be drivable for parades, shows, etc. It is really beat up. A full restoration would be a lot of work!

Brought another old Mack home recently. 1931 BC, one of 10 consecutive trucks sold to California Dept of Transportation. Very complete but the engine is stuck. It is an original BC engine. Anyone have any info one those? CID? are they the samme as any of the other early Mack engines? Seems they changed engines with every truck back in the thirties.

I looked at this truck before it was cut up. Had a v-8 detroit in it. Years later I saw the hood in Reno on it's way to you and ended up buying the cab from the same guy. Still have it, waiting to go on a 69RL700.

Can I borrow that for harvest?

Not sure if they are identical but I've replaced the bearings on an LTL that look very similar. No inner race on those needle bearings so you'll have to replace or figure out some way to repair the grooves in the shaft. Just knock the outer shell out with a punch from the opposite side, clean up the bore and press the new ones in.

And what's with the offset opening in the grill? Never seen that before.

This had to be some corporate fleet truck. No gauges, tachograph, wedge brakes. Seems like a strange spec.

Found this door plate in an add on Truckpaper, https://www.truckpaper.com/listings/trucks/for-sale/list/manufacturer/mack/model/rs600. It was listed as an RS600. Just wondering if anyone has ever seen this or knows what this started as? Glider Kit?

Have you looked at the ATHS website? There's a guy in CA selling what he's advertising as an AC. It's actually an AB. Looks like it has an engine in it. https://aths.org/backlot/8787/1924-mack-ac/california/usa/trucks/

Those don't have spring brakes so the shoes might not be stuck to the drums, maybe. Back off the slack adjusters and see what happens! If they are stuck and you can get the slack adjusters backed off sometimes you can break the stuck shoes loose by hammering on the drums. Might need to use a large drift punch to get to them. Best of luck!

Not hydraulic, definitely early s-cam air brakes. With Wedge brakes the air pot bolts right to the backing plate. None of the operating mechanism is visible.

It seems thats been done a lot. Here's a link to an article about a Northern CA log trucker who had several of them. See page 29. https://rootsofmotivepower.com/wp-content/uploads/2018/03/Roots-Of-Motive-Power-Highline-2006-April-Vol-24-01.pdf. I wonder if any survived?

Just revisited this story. I don't suppose you have the serial # for the 53 LTL? My dad and I bought an LTL out of Oroville a couple years back that was supposed to be one of Roys trucks. I'd love to be able to confirm if it was or not. It originally had a 275 in it. Thanks, Brad

My dads 1920 AB parked next to a new 2020 Mack at the Snake River chapter ATHS show last weekend. Trucks have come a long way in 100 years!
