j hancock Posted May 2, 2018 Share Posted May 2, 2018 1 hour ago, RBH said: The serial or VIN number is A40X9799. Perhaps someone can decipher this for me and tell me exactly what model A it is. It is an A model, 40 is the size/weight, X is extreme service chassis and it was the 8798 unit built. Records indicate that total production was 7666 "40's" built between 1950-1953. So it is interesting that your VIN shows 9799. Mack VINs start at 1001. Could you post a picture of the VIN plate? Quote JimIt doesn't cost anything to pay attention.

RBH Posted May 2, 2018 Share Posted May 2, 2018 Sure can, if it did not rust away with much of the rest of the truck. It will be several days before I can get back to it. Where would the plate be located giving it is still there? Sorry for my ignorance of the truck. I know so little about it, but it is in very good and will quite a truck when I am done with it and will do Mack proud.

j hancock Posted May 3, 2018 Share Posted May 3, 2018 Pretty sure on the A, the VIN plate is located on the seat bolster passenger side. Quote JimIt doesn't cost anything to pay attention.

RBH Posted May 3, 2018 Share Posted May 3, 2018 Okay. I recall seeing a plate there. I also remember it too far gone to read. I will see if it will clean up good enough to make out some of the information.

RBH Posted May 8, 2018 Share Posted May 8, 2018 Jim, Here is the VIN plate. It was on the seat bolster as you said. I cleaned it up good enough to see the data stamped into it.

j hancock Posted May 8, 2018 Share Posted May 8, 2018 Yup, that looks like A40X 9799. I guess the Mack Museum will have to figure this one out! I don't have an explanation of the sequential numbering system beside what was posted previously. Quote JimIt doesn't cost anything to pay attention.

RBH Posted July 12, 2018 Share Posted July 12, 2018 Jim, I received a response to my query from the Mack Historical Museum today. Attached you can see a letter from them regarding my truck. However, nothing was mentioned about the anomaly in the VIN you spoke of. My guess is I would need to specifically ask about this to get any response. Anyway. Among this letter I also received a copy of the build sheet for the truck reflecting it's order Number of A40X2613 and the VIN (chassis NO) at the bottom of the sheet showing in deed the number A40X- 9799 Quote Link to comment https://www.bigmacktrucks.com/topic/4255-the-mack-a-model-registry/page/4/#findComment-402355 Share on other sites More sharing options...

yelloms Posted November 23, 2018 Share Posted November 23, 2018 Hello, I am not at all familiar with Mack trucks and this one is the first one I have owned. The Model is A40T with 4829 as the chassis number. It has the extended sleeper cab with the tiny crank windows. Engine is gone but everything else remains. I planned to use the cab for a custom ramp truck for hauling cars, but I know nothing about it and I still don't, even after googling the model number. This site came up and I was hoping to learn a little about it. Thank you, -Jake Quote Link to comment https://www.bigmacktrucks.com/topic/4255-the-mack-a-model-registry/page/4/#findComment-409902 Share on other sites More sharing options...
Phase 1 Posted November 24, 2018 Share Posted November 24, 2018 The A model was built 1950-53. Do a search here for A40 and you will get a lot of posts about them. There were other A models as well that would be similar. If it is that complete, you might consider keeping it original. The sleeper cab would make it rare. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/4255-the-mack-a-model-registry/page/4/#findComment-409916 Share on other sites More sharing options...
Popular Post David 928 Posted February 13, 2020 Popular Post Share Posted February 13, 2020 I bought this Mack A40X in Laveen Arizona from a farmer. He bought it from a local contractor. He says it's been in az all its life. The engine blew up in 1982 and he bought a recon Cummins for it. I think it's a 262 that was test run at Cummins and he bought it, bolted it in , hooked up the hoses but not the wires. That was in 1982. I bought it in 2019. I removed the 5 yard dump box. I plan on fixing it up to pull a 1946 Fruehauf livestock trailer I have at our ranch. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/4255-the-mack-a-model-registry/page/4/#findComment-442647 Share on other sites More sharing options...
cncFireman Posted May 29, 2020 Share Posted May 29, 2020 That is a nice A40X you found. Hopefully you can get it finished up. Thats a long time sitting with an engine swap unfinished.

Scottyairborne Posted June 15, 2020 Share Posted June 15, 2020 (edited) Hello Andy, happy to report from my title 1952 A40T7492. Engine number EN 377 491, with a triplex. 180” wheelbase, running strong. My 15 year old and I drove it across town to our shop yesterday, about 7 miles. Photos in a separate thread that I have started... Make that A40S.

warkin75 Posted September 7, 2020 Share Posted September 7, 2020 Hey There! I have a 1950 A50H The VIN is EN291115. When I got it the original motor and trans was long gone. So I stuffed in a 5.9 Cummins and used axles from a 1995 3500HD (Dana 80 rear I-Beam front) to get 4 wheel disc brakes and hydroboost and power steering. Cruises at 65mph no problem. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/4255-the-mack-a-model-registry/page/4/#findComment-460315 Share on other sites More sharing options...

Are you 100% positive its a A50? That serial number is actually the engine number for a EN291 engine,which would have made for a very underpowered A50,those engines were put in the smaller A models. Nice truck though,cant wait to see finished pics.

Greg M Posted November 5, 2021 Share Posted November 5, 2021 (edited) Just acquired A30H 1079. Can't give you all of the particulars yet. But what I can tell you is, My dad drove this truck when it was new, and I drove it in the 70's. Taken me over 20 years to hunt it down. Bringing it home next week.

Greg M Posted November 29, 2021 Share Posted November 29, 2021 Think the A-30 I just started restoration beets your previous low number. The tag reads: A30H 1079. It also has the matching frame number. Quote Link to comment https://www.bigmacktrucks.com/topic/4255-the-mack-a-model-registry/page/4/#findComment-483710 Share on other sites More sharing options...

Mike Ely Posted January 14, 2022 Share Posted January 14, 2022 I'm hoping to find some info on one of the trucks we are getting ready to restore. Here's some of the info: W-50614, 1940 Mack, chassis 40S1023, engine #2565, pump #8445, rig was assigned to Chanute AFB, Rantoul, Ill. It was purchased along with another truck for the fire station being built there. Markings show it as a US Air Force Fire Engine. Based on the serial, I assume it is a Type 40? I'm hoping to get some wiring diagrams or parts listing since many of the original components are missing. I usually deal with American LaFrance engines, so sorry for the ignorance on these. I'm learnin' though! Quote Link to comment https://www.bigmacktrucks.com/topic/4255-the-mack-a-model-registry/page/4/#findComment-487051 Share on other sites More sharing options...
yarnall Posted January 30, 2022 Share Posted January 30, 2022 (edited) Neat truck. It is a type 40. My father has a 1941 type 45. I do not know the difference. They are based on the small E model not A model. If you have not heard , you can get some of the information you need form the Mack museum. They work on donations. They are pretty backed up with requests.

Mike Ely Posted June 13, 2023 Share Posted June 13, 2023 I noticed there isn't a listing in the registry for "Type 40". Are these included in the "E" models?
