Cub letters did 1947 have any -tell what letter you are

[wjw777]

Hello
no serial number on tractor but because of the R1 on engine it sounds like a 1947 so I want to buy parts to start fixing the ole girl up. but in catalogs it ask for type of cub the mention A;B;C: and so on what are these and what decals do I buy thank you

A Cub is a F CUB or a low boy a 154 and 184. Go to bottom of page click on TM tractor parts and go to how to ID tractor. a picture is worth a thousand words.

edit A,B and C are full size tractors

Cub is the model. International also made models names A, B, C, etc but these are larger tractors. Check out our sponsors for parts listed below at the center bottom of the page. Both TM and Hamilton Bob have new parts. TM lists decals and many have recommended Maple Hunter. Do your research on decals as they changed them several times and kits often have a mish mash of decals that come from different years. On TM's site, there is a link on how to identify your tractor. You can find casting dates on all the castings and that will help pinpoint approximate production date. A database is available with casting dates of early tractors and you may be able to come up with a range yours falls within.

I suggest this as a starting point since you are not too familiar with cubs. Don't forget page 2

Before you go too far and before you amass a bunch of irrelevant information I would suggest that you read the Owner's Manual ... McCormick-Deering Farmall Cub Owner's Manual 5-23-47. Once you have that digested .. then it would be apropos to start looking at what is wrong/needs fixin etc...

1947 would be a Q code on the castings.

If you really think it is a 47 look at the engine serial number. It might give you a close area to look for more information.

Could the A B C be referring to piston size?

[Eugene]

A, B, & C are tractor model numbers, as previously indicated.

It is true that the IH engine factory stamped bore sizes on the top of the block using letters (A,B,C, etc.) to indicate cylinder bore size. The difference between an A and a B cylinder bore and pistons is probably .0001".

Also, on my Cub's engine the letters were only visible after pulling the head. They were stamped on the rims of each cylinder.

I knew that A B & C were also tractor models, but, because he said "in the catalog" and "type of cub," I thought perhaps they might have actually listed different pistons to match the different bore sizes in the parts catalog. Should have just looked at the parts catalog before posting.

Hey wjw777,

What catalogs are you looking at?

There are some parts that fit multiple tractors. Not many, but some. Also sometimes to save space they lump everything together and you have to call in and specify which tractor you have to get the correct item. For example, "We sell engine rebuild kits for the Cub, A, B, C, blah blah blah. Call for price."
