One thing that sticks out is 3000 with aluminum hood and grill. Actually there were two different Grills, but only one aluminum hood. There were some 700 to 800 aluminum hoods built. The aluminum hood can easily be checked out by the top bars are flat and the complete grill is back spaced into the cavity. Where the steel hood grill is flush with the down legs and kicks up at each corner. The aluminum grill for the aluminum hood has three tabs on each side, while the steel hood grill has a bolt on each corner at the bottom.

Hey Dan...nice comprehensive list you've got going there. Are you planning to add & expand the list for the changes made in 1947(for the '48 model)?

Jeff

I HAVE A 1940 9N WITH A ALUMIMUM DASH STEERING AND BATTERY HOLDER.
THE HOOD IS STEEL WITH A VERTICAL GRILL. ALSO HAS A FOOT STARTER.IT HAS A 2N RELPACEMENT ENGINE WITH 90 SLEEVES BUT THE REST IS ORIGNAL.
THE GREASE ZERTS ARE IN THE FRONT AND HAS I-BEAM SIDES. IT WAS PAINTED GRAY AND RED YEARS AGO. IS THIS CORRECT? I DONT MEAN THE PAINT.

1953
Running board get built in tool box

LET ME KNOW IF SOMETHING AIN'T RIGHT OKAY?

Dan....here's a start on a list for the changes made starting w/ the 1st 8N in 1947:

4-speed transmission;
clutch pedal changed to front pivot w/ a paw-&-screw linkage;
both brake pedals moved to the right side;
brake assemblies changed to duo-servo type;
hinged seat;
hinged grill;
running boards become standard equipment;
integrated position control added to hydraulic lift;
embossed "Ford" script added to hood;
chrome & red enamel hood badge;
toolbox moved under hood, bolted to back of dash;
air cleaner door, screen, funnel integrated into hood;
oil-bath air cleaner changed to accommodate new hood;
steering box changed to automotive type(ball-nut & sectors);
longer life water pump;
metallic(sintered bronze)drain added to carb;
throttle assembly, governer, & linkage changed;
dish-style rear wheel centers w/ standard 6-lug pattern;
front rims/hubs changed to 6-lug pattern;
heavier front axle casting;
differential housing casting & rocker pin changed for longpin;
thicker housing/drilled & tapped for swinging drawbar clevis;

These were all starting w/ *8N 1*. Trying to nail down when the clutch linkage was changed to the screw-&-eye casting. Seems to me the lower link pivot mounts were different too. The axle bell casting shape maybe, to make it stronger.

Jeff

If I look in the Master Parts Catalog it shows several changes and gives serial numbers but they don't match up. Am I reading this wrong? It tells me the Ford script was added to fender at 273,000 +-?

Dan...I would tend to go w/ Smith's data on the fender script, started at 273,178.

Jeff

Well I guess if I got the 9N and 2N looking good I could expand to cover the 8N. I'll need some help with that though. I have a 9N so I tend to remember more stuff about them than the 8N or NAA.

Dan, that is a lot of time in putting this together and I didn't see anything out of place.
Dan 2N

Dan,
My 42 is 90600

It has the dog legs without holes, they mount from the inside.

Sometimes it seems like it has 400 HP and others more like 23 :)

Joe

• Good reference info

My 1940 9N35971 has dog legs that I found came off a 8N. Look at how the dog leg bolts to your frame. Should be a bracket in there that is home made like mine. I'll try to get a picture from the parts manual. These old machines change alot over the years. Mine has an 8n Center Housing because they are stronger (I broke the original) and one peace aluminum governor and TSX 241B carb. None of this is original to a 1940 9N. I didn't know this till I started looking at several others and got myself imbarrised a few times.

Lets all look into the dog leg and see what we can find out for sure.

Thanks

Dan:
I do not know how accurate this list is but it sure looks impressive. There are so many things to digest on these old girls that it would take months to put together a comprehensive, easy to understand, list like your's.
Thanks,
