May 31, 2022
The cranker is 31/2 " across in width and 3" in length vertically from the top of the round part. long from end to end and the hole that is in the middle is about 1/2 inches. The total length of the thingy with the round hole is about 4 1/2 inches. Please let me know of you have the correct replacement part/parts

Do I also need part 39-557?

Hello!

This reminds me of our 39-329 ROTO operator which is compatible with the 39-232 handle. Compare our dimensions with yours to confirm they match up. 

You won't need the 39-557. This is designed for our 39-091 and 39-092.
