Looking at JDParts, it is very clear the part substitute PN is only a short block. See attachment. JD has no right to call this a substitution as it clearly is not a substitute for the complete engine.
If you consulted with your local dealer I'd be taking the issue up with them.
It doesn't surprise me that Kawasaki doesn't want to help. JD strategically requires their suppliers to adhere to very strict supplier business rules requiring all replacement work and support to be through JD. They have done this to effectively reduce competition and to protect the very profitable replacement parts business. This allows them price freedom and disregard quality or lack of meaningful warranties.
Wish you the best of luck coming to a satisfactory resolution.
