Can anyone clarify difference in waterpumps for the d2200. My hd4 pump need rebuild and all I can find is pumps with threaded lower fitting, mine is blocked off. Can I just plug hole? its 7/8 npt I think. My pump appears to have a xpansion plug and probably not threaded. My casting #4028128 and this is the pump for sale from this site.

your water pump is the same on a 190. only difference is the original h4 had an o ring and the 190 has a gasket. I had to replace mine. quite a few things on h 190 motor are the same.
