JIS Equivalent

[Tempel294]

I have a Japanese hydraulic pump that has an unknown input spline size. I have searched though the ISO 4156:2005(E) & ANSI B92.2M-1980 standards yet have not been able to locate the proper dimensions. I am starting to think that it is a JIS spec shaft. Does anyone have access to a copy of JIS standards they could possibly verify this for me.

17 teeth
47mm major diameter
Approximately 41.25mm minor diameter

Thanks for you time.
