Questions & Answers

what type of oil do I use in the wobble pump section ?
mo houston
Hello Mo, thank you for inquiring. The Pump Oil listed for this model is part number 6.288-050.0. Please see the related parts below. Good luck with your repair!
Hello there, I have the K2400HH, while in use pressure goes on and off all the time and it's very annoying.You are forced to stop and wait. The pump does have a small permanent leak, could this be the problem? Air goes in? What would be the solution to fix this ? Thank u.
Jose for model number K2400 HH
Hello Jose, Thank you for the question. If the tank has a leak it can cause the pressure to be off and you would need to wait for it to build back up. Hope this helps!
Will K2400HH pump assembly be used for G2650OH pressure washer. If not, then suggest which assembly can be used for this pressure washer
Shashi for model number G2650OH
Hello Shashi, Thank you for writing. Sadly, the part you are requesting we do not have listed for your model, just the parts to the pump and not the full assembly. We strongly recommend you contact the manufacturer, as they would have this information in their system. Ask them for the part number you require and contact back to see if it is something we carry. Hope this helps!
I took the unloader valve out but when I removed the 2 screws there was no spring under the cap. From the diagram I appear to have version 2. Does that mean I have no spring or is it missing?
Fred for model number K 2400 HH
Hello Fred and thank you for writing We would suggest you would have to purchase a new unloader valve with the spring as a replacement if you do not already have the spring. The part number for the replacement is 4.591-040.0. We do have an article and video on "How to Replace the Spill Valve on a Karcher Pressure Washer" on our site. Just go to the front page of our site and click on Repair Center. Thanks again.

Question: Oil For Pump Housing

Mphelps1369

what type of oil does the pump housing take?? i am replacing the unloader spill valve and don't want to put wrong oil in it.
also, what type of oil does the engine take?? might as well change that too
Hi Mphelps1369 The pump takes Non-detergent oil. Many use SAE 70-90 weight oil. Some of the pumps can run on SAE 30 oil. It has to be non-detergent. As far as the engine, Briggs says SAE straight 30 in warmer temperatures in their engines. 10W-30 for colder temps. If you use synthetic you can run 10W-30 oil. Honda says use 10W-30 in their engines as I recall. When you change your pump oil, the smell and thickness of the old oil will tell you if you can use the heavier gear lube oil or the much thinner viscosity oil.
Question: Drain Plug

1207988

I need to change the valves (part 4.580-330.0) on my Karcher G2400HB. I would also like to inspect the other 3 valves under the brass plate, however am unable to remove the "drain plugs". Any ideas on how to remove? At $9 apiece I sure don't want to damage one.
I just did that. I put my largest flat screwdriver in one of the indentations and turned the drain plug around a few times to loosen it. Then with the indentations running parallel to the channel that they are installed in I used the blade of the same driver as a lever. With the top of the channel being the fulcrum put the blade in the far side indentation from the fulcrum and pry up. You will be able to get it most of the way out then use needle nose pliers.
Hello, This is great repair info for anyone working one one of these heavy duty pumps.
If you are replacing the valves, take apart the pump and pry up the caps from the inside with an L-shaped pick.
Question: Karcher Not Spraying

AJMilheiro

Hi. I have a Karcher K2400 power washer (301.0) model and once I start it, it sprays the first time, but when I release and press the wand again, it does not spray.

I heard it may be the unloader valve that needs replaced. Before I order that part, I was wondering if there may be any other parts that may be causing this not to spray?

Thank you
Armando

Hello Armando,

We have a couple of videos and article that I think will help you with the questions you have. Here are the links to them. How to Diagnose Pressure Washers and How to Replace the Spill Valve on a Karcher Pressure Washer.

I hope these will help,

My guess is that the part number, 4.591-040.0 spill valve or as other people call it, the unloader valve was replaced to take care of his problem.
