When I needed a lash cap for my 237 (also nla) I got on Facebook Mack pages and asked. In a few short hours I had an offer. Couple days later it showed up. FB can be a useful tool.

I've seen a few videos on line, the trucks are rolling in.

^^ This. I went through this 14 yrs ago with my truck. I'm maxed with building sq footage, couldn't put up carport, can't fence it in, blah, blah, blah. Plates or insurance didn't change the physical "Truck" they called it. I ended up cutting my garage up to fit the truck inside. Mike Harbison took on city hall with his field of trucks and won(after plating and insuring them all). But that area is a bit more rural then my place.

Have you checked fuel pressure? That was the second stage of my lack of power issue I had the second year I had the 237 in my truck. First the bushing on the throttle arm. Once I fixed that it started loosing power on hills, randomly. I finally put a fuel pressure gauge on the pump and hung it on the air filter so I could watch it running down the road. I had very low pressure, like 5 lbs at idle and it would drop off under load. I replaced the lift pump and suddenly I had 20 psi at idle and about 10 under load. Truck runs fine. Oops, just reread your post. Says pressure was fine. But is that under load?

Is the throttle linkage working? Getting WOT? I know the arm on my 237 pump come loose and it would drop boost/power randomly(as it slid on the shaft). After addressing the clamp it holds fine. You could drive it, but under a load it would not pull(due to lack of fuel and boost).

Looks like 3/8" bolt. Something in the 30-35 ft/lb range should suffice.

Didn't even notice that!!

I think it's out of Jay Leno's ballpark!!! LOL!! I like how they value it at $1 million. Ok, but it's only worth what someone will give you and likely not many prospects!!! Seems like the last owner quit putting money into that large pit, thus it's sitting outside for the last 6 years.

Barn fresh!!!! Little crusty here/there, but doesn't look too bad. Hows the rain gutter area? The roofs tend to rot off those trucks.

285 with tip turbine? With camelback suspension...it will beat you to pieces driving it bobtail. But it will be fun!!!! LOL!!

Yup, that was my first thought. Wheel Bearings! That old bushing stuff is not allowed on the rails today. Moving it would be more then the cost to purchase it. Then the money to restore it. Massive money pit.

https://akroncanton.craigslist.org/hvo/d/diamond-vintage-1949-lj-mack/6888669925.html No motor or transmission. No scrappers please. Text or email best. Leave message if by phone. Make reasonable offer. (330) 428-5446 NOT MINE!! Just passing it along.

Wish you were running closer to me. I'd like to check it out.

Neway air ride?

The few R models I've seen with Detroit's, have had the Farr air cleaner on them. Looks like a neat piece Mike. Wanna call Adelmans and see what they want for the two Superliners I posted?

Yup, when I had my original 673 pump rebuilt they told me that was included.

Ya, back when power was low, gearing was slow. What transmission? If it is single OD, then 55 is likely about it. My B had 4.62's and would go 65 mph flat out. A double over would get you closer to 65 mph.

So, removing the governor line from the compressor does not make it build air? Has the coupler broken and the pump not turning? Remove the intake line, spin motor with starter and see if you feel any suction.

I was at Adelmans the other day, dropping off fliers for our upcoming truck show. I was surprised to see Greg Ryder's red A model Mack sitting in the front line. I saw it for sale on craigslist recently. Seems Carl Adelman bought it and has thoughts of tinkering with it. The previous owner of my B model works at the used truck lot after selling off the towing company. Rob will remember Greg from one of his trips over this way. I went to middle school with Greg, lost track over the decades and met up after he joined up here some years ago. He has since moved a couple times and I lost track of him.

The other day I made a stop at Adelmans truck yard. I had to drop off some fliers for our upcoming truck show in Ashland. The past owner of my B model works at the used truck lot after selling off the towing company. He was out in the lot tagging some new trailers and I caught a glimpse of these well worn Superliners sitting in the back. The yellow one didn't look too hateful overall. The red one had a bunk at some time and a piece of lexan is glued in the hole. I didn't ask about them, as I have no use or reason. But if someone else is looking for a chassis give Ron a call. Typically they don't haggle on pricing. Ron's told me that before, that's why he doesn't mind "selling" there. You either buy it or not. They are not listing on their website, as they are not on the front row. http://www.adelmans.com/adelmans-truck-sales

Especially at Gerharts. After you load, you have to make that 180* cut back to go down the hill.

Can you hook up the unloader to shop air. While compressor is running, apply air to see if it quits pumping. If it doesn't, then the valve in the head is hanging up?

Ya, that was a bit before I drove it. I'm thinking about 2016? It could have been Dave himself?? We had similar builds/grey hair/beard.

That almost looks like me running it? It sounds more like a 673, then the 237? I wonder what the year is on that video? I know it wasn't that busy with people when I ran it. Dave typically ran the bucket, someone would drive the truck and his wife Nancy would run the dozer pushing the dirt over the hill for Dave to scoop up. He was not afraid to fill the bed up!! No DOT to worry about LOL!! The only downfall was the lack of power steering. After a couple hours, my hands were getting a bit red(due to lack of gloves). I told him that is why I liked my air assist.

Absolutely!! Though I've watched Dave take some hail mary runs to get it loaded on his trailer!!! But, it was his.
