Most likely it is a Bosch and the JD # would TY24486. But ask for a Lester # 12373. I do not know why JD insisted on using junk and odd ball alternators and starters so much. Bosch and Denso are not popular while Delco were available from many stores. It will be 120 amp and should cost about $120.
We convert any JD engine to Delco with some mods on the alternator to get the main bolt to 3/8 in rather than MM.
