Replacement and Conversion Checks
The 1NCJ / 12T designation is a supplier configuration reference, not a claim that these machines originally used the same Kawasaki pump. Check the existing pump model and any previous conversion before choosing an assembly.
Confirm the 12-tooth shaft dimensions, coupling, mounting, regulator signal and port arrangement. A conversion may require additional installation work; this listing does not promise a bolt-on replacement.
