JD /Kawasaki parts.

The Kawasaki model number on my JD GT245 doesn't show up in any Kawasaki parts suppliers options. I'm guessing this is because its a proprietary JD number. The # is  FH601V-AS15. I'm trying to figure out what non-JD engine number would match up for parts. Would the AS-14 or CS-15 numbers be a similar engine?
