AR RCV3G27 pump off Vortexx Pressure Washer Troubleshoot and repair

I purchased a Vortexx Pressure Washer with a Honda GX200 Motor, this original AR RCV3G27 Pump and a Mi-T-M pump.  Both pumps were not working.  Here is the troubleshoot and repair video for the AR Pump.  This repair was pretty simple, the unloader was stuck from rust/corrosion and the pistons were cracked.  I cleaned the unloader and replaced all 3 pistons even though only 2  were cracked.
