Need pump rebuild kit and cash box.

Your Doughboy machine more than likely needs more than a repair kit. The problem most of the time, is that the top cover on the hydraulic clock/pump is rather thin and the area where the main shaft comes through (the bearing area) becomes worn and elongated from the constant movement of the shaft and consequently will not seal, and the fluid in the pump leaks out. The solution is to bore that area out and refit it with a new bearing. This is a very common problem with that type of clock mechanism on the Caille machines.
