There's getting to be a lot of interst on this board on SC's. I really didn't have much intrest in them untill I picked up a 41 two summers ago. Since then my stable has grown to 7 units - three running, one project and three donors. There have been several posts about 41's. I'd like to hear from those of you who have one and what you serial number is. My serial number is 4501360. I've got it back to origional with the exception of the air cleaner (I think I found one last weekend) ,one chrome stip for the hood and the rubber grip for the clutch lever. Following is a list of serial number breaks from 41 and early 42 that distinguish those tractors from the later models:
4500001 - shipped to Atlanta, GA on 11/4/40.
4500789 - last unit built in 40, 12/31/40
4501149 - Battery cover and fuel tank bracket change, light mounting change and a shallower sided hood design.
4501845 - spindle lower bushing change.
4503029 - exhaust/air stack moved from center of hood to the outside.
4504858 - change from case to bendix brake design.
4505420 - front wheels changed from stamped steel to cast.
4506573 - choke rod changed to flex cable.
4507452 - operators platform restyled.
4600001 - chrome strips removed from the hood and rear fenders changed to shallower design.
4600728 - rear wheels changed to spoke design.

I have yet to come up with a serial number break for the change from the smooth block to the ribbed block. I know 45001360 is a smooth block, but don't think that there were many more made that way.

Hey guys! I am back... Been along year in school so far. Ya'll know about my '41 SC. It took me almost 4 years to restore. My serial # is 4501960 SC. Here is a list of differences that I found among the early to late SC's:

Most importantly- the bore and stroke was smaller on tractors up to 1951-it changed from 3 1/2" to 3 5/8"??Center Exhuast and air filtration, The air filter assy. had an "S" tube going to the carb rather than just having a box down the side and have a straight hose to the carb which was changed in 1942, some were offered without oil filters on the side of the engine-optional equipment, Larger shelled fenders-they extended further over the rear tire, with a light facing forward, a different front spindle bushing (prior to tractor 4501845) and a light facing rearward, a different gas tank support (up to serial number 4501149) A different fuel strainer bowl-to serial number 500000 , the flat rear wheels were standard until 1945, and then spokes were converted from optional(1942-1945) to standard in 1945, and flat rear wheels were dropped,Steel wheels were offered for all tractors, I have yet to find me a set, the steering wheel prior to tractor 4600001 had 6 spoke, instead of 3, a variation of clutch levers were used, mine for instance is similar to what you described, only it comes to a point on top, and is more narrow of a handle. They also had a thottle lever prior to tractor 4600001 that came straight up rather than curved over the seat mount which they droppd because they had complaints of trouble getting into first gear when tractor is at idle because the lever is in the way. These are just some of the changes. They had a variation of different parts- hitch styles, etc. that were put onto these old SC's. No SC could ever be exactly the same. Too many little differences. Talk to you later. It's been a while since I posted something in here!

I've got a '41 thats awaiting restoration. Its serial # is 4508365SC. It has a non-ribbed block. Flat wheels, good rims. Gave $100 for it several years ago@ an estate sale. Story @ sale was that owner took it apart, couldn't find mains & just stuck it back together to keep parts from getting lost. Its all there, I think. Gotta get at it, as I've found a place where I can get the main bearings re-babbited. (My $0.02 worth. jal-SD)

Fascinating info, Don H. I see you've been reading "Full Steam Ahead" as well! (grin)

Thank you for sharing the info. I'm keeping track of 1944 S-series serial numbers to try and figure out when the wartime bronze brake pedal variation started and stopped. No particular reason... I just started saving the info after people on this board started discussing it.

I saw something in Full Steam Ahead on the D-series that I was wondering about: According to the book, running engineering changes were noted on the build sheet for the tractor at which they occurred... and then these numbers were transferred to an index that catologued the changes and the numbers.

On page 242- it lists the 1949 engineering changes to the D-series, and it says that a change in production to a high capacity radiator was made at Tractor No. 5313086.

Well, the build sheet for my '49 DC-3 shows the installation of a high-capacity radiator at model #5303113DC- earlier by 9,973 tractors (spread across all model series.)

It's just got me wondering if my tractor really just had a "special order" option on it, or if this is actually where the engineering change took place.

Anyway- keep us posted on what you find out about those '41s.

Regards, -Schotte

Mike,
One thing I've learned over the years (I've worked for Case for 25 years now) is that you have to take the old serial number breaks with a grain of salt. Tractors would get held over and re-numbered. Case in point the VAC's and I'm sure it happened on the Racine built tractors too. The breaks in the books are close, but never exact. That just adds to the fun of our hobby. In the 30's and 40's Case would build a one of a kind tractor if some one ordered it that way. That just adds to the confusion today. The best bet is to try and get the build sheet for your tractor.

I've got a 44 in the yard as a future project. I'll have to get the paint off the brake pedals and let you know they are made of.
