Strange 1940? Chassis VIN number

[Cometeguy]

I bought as chassis a few years ago with a very strange VIN number. It appears to be a 1939 to 1941 pickup. VIN is stamped in the normal place on the left frame rail, but the number very clearly reads" *9T 570*. This does not correspond to the coding for 85 hp, 95 hp, 60 hp or the numbers used on other 4 or 6 cylinder chassis. Also, it doesn't appear to be Canadian.

Anyone seen this before or have any answers?

got any pics of the cross members? I have a very strange 40 frame, but is a full gauge thicker everywhere, and the crossmembers are .125 thicker, with reinforcements, and sit 2 inches deeper (so car sits 2 inches higher) there was also some special adapters for the front fender "wishbone" odd lengths. Ive seen one other front cross member like it, but it was bolted in, mine is factory rivets, never seen another rear like it tho.

My serial started BB18- which is also odd.

Looking for some 18inch "wide 5" rims for this chassis, got a high clearance chassis, would like some high clearance rims to go with it

Any chance the thicker deeper frame was special for something like the Marmon Herrington vehicles?

I have a 1941 pu complete chassis with 9n tractor 4 cyl .
SN *9c-25##* four digits: trans # matches

Do you know where a 4 cyl SN list is?

Can you read the SN on left mid frame or back cross member?
Does chassis have 5 wide brk drums
A 39 Merc with original 81T head could have been installed with 3 or 4 spd trans
in special 39 1/2 t commercial car chassis --4 digit SN fits 39 99 block--though
prefix appears mis stamped.
239 not supposed to be in 1/2 t---but! Gene

It had no drums on it, but did had the Early 40 sway bar set up, and also had a 4 speed. Also had a much larger master cylinder, and an oil bath aircleaner. 21A (reconditioned tag, but couldnt read any of it) motor. It came under my coupe (which had an early dash as well), it was so nice, I used it, cause its what I had, but would like to build the right chassis for the coupe, and use this one under a 39 sedan delivery or PU. Unfortunatly, the trans was split in two, and I never looked to see if the numbers matched, and its gone now. There was no serial other than the front one on mine. It came out of Nebraska I believe. Im a bit tired of the massive wheel gap! Lots of differences in frame, difference size and location of holes in X member, also had different "webs" from the front cross member to the frame, the center box of the X was a bit different. It would take special spring u bolts as well, cant remember what was off tho, i think the threads didnt raise high enough, and required washers to fill the gap (think I eneded up getting modern ugly ones because they were full thread), and even the cross piece wouldnt fit right, at least not with the 40 spring I put in it, guess I should go count how many leave the spring that was in it had (i think its still together, somewhere in the shop). Needed the longest shock links I could find as well.


edit: BUT it did have 39 rear fenders on it, and a steering tube unlike any I had seen, looks like a 40, but all steel (not that die cast top) with NO column shift stuff. bigger top than what I think is the 39 column I have. It also had a single horn mount on the frame, instead of the inner fender panel.

PS Sorry for the Hijack, But was just wondering if your odd serial frame looked like my odd serialed, ODD frame

Thanks to all for the responses. Still haven't figured out the riddle. It appears G32s response about his serial number 9C for 9n tactor is the most similiar. Way closer than 18, 99, or the others for earlier 4 cylinder or 6 cyloinder.

Any other ideas out there?

18 is for 85 hp engines, 99 for 100hp engine, G for 6 sylinder also H for later 6 cyl, N is for 4 cylinder tractor engine--T for truck, C for commercial 1/2 ton. I also have a 4 cylinder tractor engined 1/2 ton 1941 pick up.

[Cometeguy]

Thanks Alan. What is prefix on your 4 cylinder pickup? NC? 9C?

Still like to have a (9n) 4 cyl SN list ---actually only 41 & 42

A 1/2 41 or 42 PU with optional 4 spd truck trans might 9T SN.
There have been 41 PU for sale with 3 & 4 spds.
Need chassis evidence of 9n or 239 engine.
Dual pipes--cross over pipe--v8. 9n had rt side 1 1/2 ft down pipe.
v8 fuel line goes up firewall to rear top of engine.
9n fuel line goes along left frame & across front crossmember to rt front
side of block mounted fuel pump.

9T 3XX on my 41 truck 1/2 ton

[agshelby]

Responding to this 6 year old thread. My 1941 Truck as a clean serial number stamped on the frame that reads 9C 32xx (x- represent numbers, don't want to post my entire serial number). The frame on this truck is very clean with no rust or evidence of repair and the title matches that serial number.

This is a V8 truck with a columbia overdrive. Any ideas on why the serial number is so unusual ?

3 speed or 4 speed trans? think 3speed used C and 4 speed used T

[Mac VP]

The 3 speed versions had the usual top loader gearbox with the 78 case and the 81A-7222 double detent shifter tower. However, inside was a special low ratio gearset (with the good 39-48 type synchronizer) that Ford developed for use with that little 4 cylinder flathead. I forget the actual ratio but it used a 14 tooth drive gear against a 29 tooth cluster gear.

[rotorwrench]

The 9N engine didn't develop enough horse power for most folks and I'd be relatively certain that that one ended up with a V8 due to that. If they changed the engine then they likely changed the transmission as well. There was a change in Pickup frames in 1941 that came somewhere in mid year so that the G series 6-cylinder could be used. It was basically just a cross member change. Other than that, the frames were about the same as the 1940 pickup. The cars in 1941 had a different frame so they don't interchange.

You might just consider starting a new thread for stuff like this. A person can always link an old thread on if they feel it is relevant.

Any chance it is a 4 cyl from Canada, hence the 9C? I once bought a $100 41 pickup for a friend that had a 4 cyl. That was 40 years ago and I never even looked at the VIN.

[alanwoodieman]

both of my 41, 4 cylinder pu's had 4 speed trans

Mike....As far as I know (for what little that's worth), that first letter AFTER the number denotes vehicle-type application, i.e. "C" equates to "Commercial", or "T" means "TRUCK", or "A" signifies "Passenger car" as primary use. That FIRST number is usually some sort of "year" identifier. Canadian stuff usually starts-off with a big "C" at the very beginning of the sequence, but WTF do I know? DD

Benson has a wealth of interviews from fords employees on file. Seems like one of the engineers talked briefly about a frame with a heavier gauge steel. I will look to see if I can find the reference.
