Serial Numbers

[Paul Heise]

Hello all, I found a census number on the side of my doors ( 42 F15a ).* I also don't have a serial number on the frame or on the gear box (must be a rebuilt?).* Can anyone tell me the relationship between the census number and the serial number, if any, and if they could be the same.* The number that I found was 55-XXX, only a five diget number.With all that in mind, does anyone know where I can get a set (x3) data plates, new or used? or someone that makes them for a Ford.

[Jim Price]

Can somebody give me some information on this number found on the front cross member of my F 8, O1T (first line) 5020 (second line)? See picture.

Thanks!
Jim

The 01T5020 is a Ford part number for a cross member. The first part of the number, 01, is a code which will tell you the year the part is introduced. The T will be for truck. The second part of the number (5020) is the Ford group number for a #1 crossmember. My manuals give a newer number than this, so possibly there was a production change.

Ford part numbers system did not change since the mid 30s, and was still using this basic system when I was dealing with commercial Fords in the late 90s. One must note that on most newer Ford parts, the number, while looking very much like these part numbers, may only be an engineering number,and require that the proper part number be looked up in the catalogs.


Paul: There is no correlation between the serial number, the earlier DND number (ie: 42-1-101), and the later style numbering system (55-123). The change occurred somewhere late in 42/early 43, and trucks numbered under the old system were re-numbered into the new system.

By what little research I did at the Shilo museum years back, it would seem the earlier numbers were applied to whatever vehicles were in an area. I found records of many trucks and staff cars which were within a few digits of my DND number, and they were of entirely different vehicle types.

For the cab 13 F15cwts, the serial number was usually on the rear left frame near the spring hanger. But there seems to be a period in late 42 where they weren't doing this yet, I have only seen 1943 trucks done this way.

The part numbers are civilian Ford standard codes relating to the Ford model code for each chassis ... e.g. 1 ton or 3 ton or whatever.

I know that the 01Y prefix = 1940 1 ton chassis 122" w.b.

I think 01T = the 3 ton model .

They may have used the front crossmember from the civilian 3 ton model on the F8.. maybe you can find a 1940 or 41 3 ton truck and compare the crossmembers .

Thanks, Rob and Mike!
Am I to assume that my F 8 is more than likely a 1940 "model"?

Well, they may have used 1940 civilian parts in it here and there. I am not that sure on F8's, having never seen one. We got the superior version out here ! Even then , they were tainted with Ford parts in the cab area.

Jim, all the Cab 11s should be 1940 models. The Cab 12 came in in late 1940 (Nov or Dec). Having said that I suppose there could have been a few that got assembled with 11 Cab parts after that but who knows? On my Cab 11 F15A the serial number is stamped in the vertical part of the frame under the passengers door. Any Cab 11 or 12 Fords I've looked at had the number there. On these trucks the serial number is the same as the engine serial number.

So far as Chevrolets were concerned ALL British orders were '1941' Models, with production starting in September 1940, BUT run-out Canadian orders were '1940 Models'. The change-over was possibly at # 084XX04002 AND 184XX05004.

Fords started their British production at the very end of August, a few days before GM. There were definitely # 11 Cab British 1941 Chevrolets because of the differentiation by Oshawa. Now I am put on the spot I assumed that the same applied to Fords. So I checked the 1940-41 Ford monthly engine #s and the last 1940 '1G' prefixed were as at October 1st, and there was a very short overlap I think with the 1941 Model '2G' series which officially also started October 1st 1940. It is just possible that '1940' production continued whilst '1941' engines were produced to meet contractual requirements.

On the basis that Windsor production started in early Autumn, there must have been '1940' Model British # 11 Cabs, although internally they may have been classified as '1941'. At the time of course the engine # was the identifier for Fords. There were definitely 1940-built # 11 cabs for the British and as suggested by D.P. there may have been '1941' # 11 cabs Ford for either countries.

I must add that this amazing overlpa of Model Years was to remain unique.

David:
Thanks for clearing that up! Although there had been references to the serial number being stamped on the frame under the door on the passenger side, I had assumned that it was under the floor on the top edge of the frame. Will check out that vertical location tomorrow!

David (Hayward):
Thanks for your input on my question regarding the number on the front cross member of my F8. When I checked my parts manual dated January 1942, the front cross member in it was numbered 5019 not 5020. Interesting!?!? Wonder if my part came from civilian stock?

Regards,
Jim

David (Haward):
Got under the door on the passenger side and wire-brushed the frame. Lo and behold, there was this number: 1G-6461 F* Also looked at the motor block and it was numbered C69A on the bell housing.

Thanks again!

Jim

Jim, I'd guess with that motor number that it would have been made in June of 1940. It must have been one of the first ones with the cab vents. My F15A is 1G-10495 and it would have been made in August 1940.

[rob love]

Rick Yuke from MooseJaw had a F15 that was just a bit under the 6000 serial number if I recall, and he did not have the vents, so cletrac's timelines are right on. I had F-15A serial 1G10616 as my first CMP restoration.

If someone has Peter Ford's old infoex data, Rick's serial number was in there. I believe his truck was sold to Alberta, mind you.

The C69A engine block casting is a postwar 1946 model. The engine number itself is found in a variety of places, like the flats of the Inlet Manifold surface, and sometimes not even on the engine itself (ie: Could be on the bellhousing)! Look in these locations for the number:

Thanks, David, Tony and Rob for your input on the serial and engine block numbers! The historical info adds to the story of my truck!
