Or sometimes the casting reads as 1827-1R
This is the info I’ve found while trying to fix my Steiner 430 Max which has float issues where the detent is badly worn.
The John Deere AM132338 is I think the same as the Steiner #23-041 available at Messick’s for much less $ than from any green parts store. I cannot find the dukes part number other than as mentioned in the DCV Technical Document PDF mentioned as “Float conversion (add float detent kit A to standard T spool)” but again, I can’t find the OEM float detent kit part number.
