Description:
This is a genuine item that is specially designed for use with Karcher pressure washers. It is supplied by the original equipment manufacturer. The oil helps to lubricate internal components of the pump to ensure it runs properly. Check the oil level regularly. Oil level should always be between the “FULL” and “ADD” level marks on the dipstick. Be sure the machine is level when checking the oil level. This will prevent them from wearing out. Refer to the owners manual of your model for the correct application of this oil. This synthetic 15W40 oil is sold in a single 1-liter container.

Questions & Answers

How many ounces of oil does this pump require ?
Cecil Hindman for model number G 2400 HH asked on 2019-05-01
Hi Cecil and thank you for your questions. Just to the bottom of the filler hole. Hope this helps.
Pump Oil 4.591-040.0 I need to replace the pump oil on my machine. My question is-- how much oil does it take to fill the pump? I do not have a sight glass or any other indicator that I can find. Thanks in advance. Jerry
Jerry for model number Karcher K2400HH asked on 2020-03-19
Hi Jerry, Thank you for your question. The oil level should be level with the bottom of the oil filler neck. When you check the oil level on your pressure washer, make sure that it is on a level surface. We hope this helps. Thank you and have a great day.
Where do you find the port to add oil to the pump
Clide asked on 2019-11-10
Hi Clide, We would be happy to do some research to find you the correct parts. However, we need your model number and the brand name to locate any information on this. Model numbers can be short or long, and could have a mixture of numbers and letters. Thank you for your question and good luck with your repair!
How much pump oil (6.288-050.0) does the pump hold? Is more than one (1) container needed? I didn't notice a servicing port...if one exist where is it?
Denis for model number K 2300 G asked on 2019-08-27
Hello Denis, Thank you for your question. When you fill the pump oil, fill to the neck of the oil filter. The container has 1 liter, so you shouldn't need more than one bottle right away. Hope this helps!
I asked a previous question concerning the oil level. This is not and engine oil level question. The oil level I am asking about is the pump itself. The engine is a Honda. The pump is a Karcher. I'm questioning the oil level in the karcher pressure washer pump. As I said previously I have replaced parts in the pump and need to replace the oil that was lost during the repairs of the pump not the engine driving the pump
R for model number G 2650 OH asked on 2019-08-11
Hello R and thank you for writing Here is the link to your manual , this should help https://www.manualslib.com/manual/795633/K-Rcher-G-2650-Oh.html?page=11
Replaced some valves and need oil capacity for reassembly
Ronald Mace for model number Jar her G 2650 OH PUMP asked on 2019-08-11
Hi Ronald, all I could find was this in the manual Oil level should always be between the ?FULL? and ?ADD? marks on the dipstick. Any other information we would recommend contacting the manufacturer directly for. Thank you for your question and good luck with your repair!
Type of pump oil and types of motor oil?
Dave c. for model number G2600 gas karcher power washer asked on 2019-07-28
Hi Dave, the part 6.288-050.0 is the correct pump oil, however you would need the engine model number to research the correct engine oil. Thank you for your question and good luck with your repair!

Pressure washer pressure pulsing very fast with high pressure
1. Purchased all most likely parts likely to cause problem: valves, seals & springs.
2. Disassembled pump. No oil in wobble plate housing - only some water. (Probably piston seal?)
3. Cleaned housings, reused parts with carb cleaner. Added 15-40w oil. Reassembled & installed.
4. Works better than when I bought it, (was rebuilt unit.)
5. I found seals a little tricky to install as they are flared out & you'll probably try to use a screwdriver to install - careful, easy to damage seal.
6.Also, check the spill valve before you remove pump - it can cause erratic (as well as low) pressure.

Pressure washer lost pressure
I followed the instructional video for my model of pressure washer step by step and the repair went very easily. I removed the pump from the drive shaft and took it apart, removed all of the parts that needed to be replaced, cleaned the pump housing parts, put in the new parts, filled it with new pump oil, reassembled the pump and connected it to the power shaft.

It now runs like new.

I found the instructional video a great help and couldn't have done it in the short time it took.
