super c year

Is it the engine your and your questioning whether it belongs in the Super C. Well the part number 354898 R1 is indeed a Super C engine block. It is also a Super A engine block after serial number 310300. The only difference in the two applications will be the Super C has 3-1/8" bore sleeves and matching pistons, while the Super A will have thicker wall 3" bore sleeves and matching pistons. If that is what your trying to figure out, shut down the computer and grab the wrenches, as that is the only way your going to find out for certain. Take the head off.

You'll have to find the block date code to be sure which of 51, 52, 53 or 54 the block was cast. That engine may well be in a C now, but it did not come in a C.

If most of the major castings on the tractor have a similar date code ending in "X" then it's a safe bet that the tractor was built in 1952.

However, if the major castings have different date codes, you have a "mutt" built from parts tractors.

The number ending in R1 is the part number for the part. That tells you nothing about the date of manufacture.

Look on the side of the tool box under the seat for an aluminum plate about 3 inches X 4 inches. It should have the serial number stamped on it. Then click on the "Serial Numbers" link at the left and look up the year.

If it is a 100,000 or higher, it is a Super C, if it is 5 digits or less, it is a Straight C.
