My hydraulic pump quit and I got the rebuild kit from NH. I put some witness marks so it goes together the same. Everything looks worn. I'm not sure how it goes back together as the plastic pieces on mine are worn. Also I didn't undo the nut as I'm not sure if I need more witness marks. Anyone have advice or pictures of their pump?

Witness marks are not needed, and could be a problem on the impeller if they interfere with end gap. Do you have a manual with clearances and end gap dimensions? Main thing is to clean very good, look for scored worn areas, check clearances, measure diameters of shafts and bores.

The witness marks are on the outside. The only specs I have are in the picture I attached. Ill clean it up good and ho from there.

If all that came in the "rebuild" kit are the plastic seals and rubber O-rings it looks more like a reseal kit,
if the issue was the pump being worn it would be gear to pocket wear.
I wish you luck with your project and hope it works for you.
