48" LT Deck DOM

[wex005]

I have a 2165 with a 48" deck that needs the double pulley bearings replaced. It looks like there are two options depending on the deck dom.

Cub Cadet 741-0524
Bearing, Ball, .62 ID x 1.57 x .44 Thk
(Mfg. Date H140 and Before)
Cub Cadet 941-0524A
Alternative for 741-0524: BEARINGBALL


Cub Cadet 741-1122
Bearing, Ball, .625 ID x 1.574 x .470 Thk
(Mfg. Date H150 and After)

I am not able to find either of these (H140 or H150) dom. My deck has MFG. Date tag with E23664.

Does any one know how to determine the dom of the deck?

Thanks,
