Karcher Pressure Washer Control Head Conversion Kit 9.002-011.0

Description is a bit misleading as its Direct swap for original part on K4 . Be careful to keep the pump assembly upright when dismantling otherwise oil will leak from the motor drive casing. Be sure to transfer other internal valve parts from original unit. It restored my K4 unit to full operation.

My washer sprung leaks from both the control head and the bit beneath with three chambers. If Karcher wanted a product that would last they'd have made both from metal but that is just my opinion. It wasn't clear to me which control head I needed as both appeared to do the job and this one was called the conversion kit. I couldn't find information anywhere about why the conversion was needed so I chose this control head only because it looked like the one with a leak. Fitting is fairly straight forward but be careful to keep hold of all the spacers and fiddly bits attached when you take it apart! I lost one for a week and found it at the end of my workbench. Then tightening the whole assembly needs three hands! I have a torque wrench and tightened the screws down to the same torque as I used in days past on car cylinder heads. All fixed now and the washer is much more vigorous that I recall! It must have been leaking for a long time.

Exactly what was needed , The parts replaced the existing one perfectly and I now have a fully functioning machine after a little bit of tweaking. Well worth the effort. I will definitely use ransom spares again.
