That motor is non-reversible. (At least without reconnecting the winding inside). As was posted earlier, many offshore motors are manufactured for a set rotation.

I don't mind if you repost the list. Maybe a disclaimer it may not be 100% accurate. I spent a few years in the motor repair business and used to see a little bit of this stuff. :lol:
I know GE motors can be hard to accurately date. I only know some codes from those old Triclads from working...
I've compiled a list to the best of my knowledge. If anyone knows something different, let me know. Century currently uses a different serial numbering system.
Year Code
1938 R
1939 S
1940 T
1941 U
1942 W
1943 X
1944 Y...
I should compile my notes better, but V is the letter that is skipped. They used the two character code until the early 60's and then reverted to the single character again. In the early to mid 80's they went back to two characters again. I'm not sure the exact years but I have it somewhere...
You are correct for the 1948. If you work back you'll see that they used AA for 1946, AB for 1947, etc. They seem to have ended their original run of single digits in 1945 with Z. In 1938 the year code was R, but I haven't been able to make sense of serial numbers before this. I have another...
David,
Your 3HP Century was built in October, 1948. The 1/4HP is indeed a pre-1938. I have the identical motor in my collection with a CF6 serial number. I'm sure someone from the 40's or 50's knew these serial codes, but I'm afraid they may be lost forever.

I don't have a list per se, but if you have a date code I can probably decipher it. Century motors manufactured before 1938 have straight serial numbers that I can't decode. Date codes will have a month code of 1-12 and a year code consisting of one or two letters. They can be in any order and...
They were very quiet and extremely smooth running. The date comes from the No. XV.
In GE's date codes X is October and V is 1961. I have repaired many of that style, they were used extensively on Brunswick bowling ball returns and Dairy Queen ice cream machines.
