1) watched several (multiple times) You Tube videos to understand the inside workings.
2) worked at removing the Actuation Housing. I realized that the key was probably rusted, and with some lubricant removed the housing.
3) Had to get Karcher USA to email me the owners manual and parts lists. (very timely/responsive).
4) three different orders placed, after realizing parts needed replaced.
5) Did not understand when replacing shaft seals (pt no 6.365.393.0) if the groove was to be oriented up or down.
6) Same thing for groove ring (pt no 6.365.394.0)
7) Assembled with new parts, but water still spews out between the 2 housing halves.
8) Water mixed with oil is still present. I will need to disassemble, clean, and consider other part replacement. The PW worked fine with wand activation at the startup, but the water side seems to be leaking into the oil reservoir and forcing oil out. I was surprised to see behind the swash plate (wobble plate). May have to disassemble the to place the seal ring (pt no 7.367-018.0).
