Here is my research on the available drawings on 9N front wheel hubs and hub bolts:

Hub assy 9N-1104-A1 included parts 9N-1106-A1 hub, 78-1107 bolt, cup B-1217(outer) and cup B-1202 (inner). All hubs used same cups, so I will not repeat. The –A1 hub was made of malleable cast iron or optional cast steel and had three straight radial ribs ½ inch high from depth of valley of dish. It is the only hub with ribs inside between the bearings. Earliest date on print is 4/13/39. 1 inch diameter raised bosses were under bolt heads.

Hub assy 9N-1104-A2 included parts 9N-1106-A2 hub and 9N-1107-A bolt. The –A2 hub was a steel forging and had no reinforcing ribs except for a small drive lug (for machining) between hub and dish. (You wouldn’t need the ribs with a steel forging). Earliest date on hub print is 7/7/39, but assy was not released until 11/42.

Hub assy 9N-1104-A3 included parts 9N-1106-A3 hub and 78-1107 bolt. The –A3 hub was made of cast iron and had five fairly deep s-shaped ribs. Because of the s shape, these ribs would probably not have been so good for machining drive lugs, so there were two rectangular lugs on the wheel side for this purpose. Earliest date is release date of 2/44.

Hub assy 9N-1104-A4 included parts 9N-1106-A4 hub and 9N-1107-B bolt. The –A4 hub was made of low carbon steel plate and has a Kelsey-Hayes number in the border. Drawing was completed in 6/44 and released 10/44. The holes for the hub bolts are bigger (.592/.602) than any of the others and would, therefore require another hub bolt.

Hub 9N-1106-A5 does not seem to have had an assembly drawing, as the 78-1107 hub bolts are called out on the machined part drawing, whereas, on the others, they are called out on the assembly drawing and only referenced on the machined part drawing. The part was made of malleable iron and had five straight radial ribs with large radius tops to them. There were 1 1/8 diameter raised bosses under the bolt heads.

All versions specified swaging or staking the hub bolts into place in the hub flange. All versions except –A4 reamed .562\.563 holes to press in the hub bolts.

Now for the hub bolts: 78-1107 came from 1937 passenger cars and had 1.46 overall length (OAL). The head was to be stamped with F for Ford, K for Kelsey, etc., depending who made it and the neck was smooth. Released 2/38.

9N-1107-A was 1.29 OAL and head stamping was not required. The neck was smooth and was released 7/7/39.

9N-1107-B was 1.27 OAL and head stamping was not required. The neck was ribbed or fluted with 39 flutes which had a diameter of .6125/.6225 inch. Head stamping was not required. Kelsey-Hayes number 27991 is on drawing. Released in 10/44 but not drawn until 3/46.

2NAN-1107-A1 was 1.72 OAL and head stamping was required. The neck was smooth, and was released 11/42. Note on print says Used With 9N-1106-A1, A3 Designs Only.

2NAN-1107-A2 was 1.55 OAL and head stamping was required. The neck was smooth and was released 11/42. Note on print says Used With 9N-1106-A2 Design Only.

All hub bolts were zinc plated.

There is one more hub assembly I cannot read completely yet, but it is 2N-1104, released 4/46. Will post its contents as a followup when I am sure of the numbers.
I have not found a drawing of a hub with three s-shaped ribs as in Stumpy’s pictures of 2/28/06. There will always be some unknowns.

The 2N-1104 front wheel hub assembly is unlike all the other hub assembly drawings. It is a typed list of components only, on a drawing form. It shows
(1) 7N-1106 HUB-FRONT WHEEL
(1) B-1202 CUP-FRONT WHEEL INNER BEARING
(1) B-1217 CUP-OUTER BEARING
(6) 7N-1107 BOLT-WHEEL

It was drawn in 11/45, and released 4/4/46 and never revised other than the "R" being added to border indicating it was used for repairs only from that point onward. That action is not dated on many prints, so the engineering information sheets would have to be consulted to see if this was a service part only from the very beginning. We do not have any 7N part drawings that I know of. It will be unexplained until we do more research.

Randy, as you probably know, the B-1201 brg; B-1202 cup; B-1216 brg; and B-1217 cup came from the 1932 B Model car front wheel bearings and were used through 1954 I think. I found a K-2 stamping on the forged hub with no reinforcements which would fall in line with your November 1942 release.....Kelly.

Do any prints say Budd Co.? Some hubs have a casting date around 1943 and Budd on the inside.

Scott , I have a set of hubs with Budd stamped in them!

Stumpy

No such luck. I think the basic policy was not to put suppliers' names on prints, so it is the exception when this is found.

Randy, thanks much for doing this. This answers the question why the lug bolts I replaced didn't fit. I have several different front hubs, I'll try to identify using your report and take some pictures when the weather warms....thanks again, Kelly.

Randy.....thanks for the correct info and for the time you spent going thru your drawings.Do you happen to have any info on the Ford headlights? don b

Yes I can find some, but where do your interests lie? Are you looking for release dates, markings and finishes or ???

Randy....according to the prints I have,Ford made headlights[non-sealedbeam],obsoleted,and went to sealedbeam.These lights looked like the Tract-O-lite lights.The last change date I can find on the prints was 2-13-47.I suspect the Ford lights were used on the 2N and early 8N's [48-49].My questions are:
How long did Ford make these lights?
What year models were they used on?
How were they stamped?
Did Ford produce them or have them produced?
Was Tract-O-Lite a company name or a trademark?
Was Duolamp a company name or trademark?
When was the Tract-O-Lite headlights installed on the 8n's?
When was the Duolamp taillight installed on the 8n's?
Who made the 8n implement light,how was it stamped?

Many thanks for you response.........don b
