Question: Karcher Gas Pressure Washer Wate...
I have a Karcher pressure washer model # G2650OH part #(11945130) .
My problem is that I have a moderate to heavy water leak out the bottom small hole between the brass pump and the middle housing. Water flow increases with trigger / motor increase in RPM. I opened the three part pump housing assembly and also found the oil in the cast assembly portion to be contaminated with I believe to be water.
What is wrong, and which parts specifically do I need to replace to correct this issue?
Question: Kercher Power Washer Question
I accidentally ran my Kercher power washer G 2650 OH without the water hose attached for a few minutes, while I was testing the carb adjustment. Now I don't have any pressure when I attempt to use the sprayer.
What parts do I need to purchase? 1) A completely new water pump component; 2) a valve/washer kit or 3) each valve internal part separately (hard to tell which parts are needed because none of the parts appear damaged)?
Also what type of oil should I use in the wobbler chamber? (Non-detergent 30W?)
Question: Spill Valve
I have the Karcher G2650 OH. The spill valve does not look like the one in the diagram. When I pulled it out, only got the top part with the green o-ring and the spring. Does this mean that it broke in two? If so, how do I get the bottom part out or do I need to take the assembly apart?
Reply: Spill Valve
I checked with the manufacture about the question you had regarding if the 4.591-040.0 spill valve is the correct one for the model G 2650 OH. They assured me that it is the right one. If the shaft of the spill valve came out when you pulled it out, and the rest of it is still at the bottom. It looks as if you will have to remove that part of the pump to see if you can get the remaining parts out.
