pressure washer unloader image
johnborgli
Engine runs fine. Very low pressure comes out of the hose. I think it's something to do with the pump. Can I adjust or remove something to get more pressure.
Answer
Check your water inlet to the pressure washer. If water is restricted it cannot build pressure
Make sure you have the right tip and it is working properly. A pressure washer is designed to put x amount of gallons through x size hole to produce pressure.
Try adjustment near number 26 which appears to be an unloader. Line drawing is very poor best guess.
The valve would be under a hex nut on the pump head and if debris is in them pressure will fail. They are a spring seated assembly. they come out after the cap is off with a pair of needle nose pliers
With a better line drawing I could offer more advice but again the drawing is very poor.
I would not recommend try to remove the pump from the motor as it appears to be a wobble plate which are spring loaded and difficult for an experienced repairman to reassemble

Water in oil - pressure washer pump?
eight_kind
I have got water in my pressure washer pump oil. Im sure this means the seals are gone, but why isnt it leaking water out from between the head the the crankcase and onto the ground? But yet it can still push water into the crankcase? I dont understand that part. Do i have a problem other than the seals? The pressure is kinda low, 4000psi unit, 4gpm and only running 2300 psi or so with a 4.5 nozzle. Should be about 3500 i think with that nozzle. I did adjust the engine speed down a little but not too much. Pressure does build up to a little over 4000 psi according to the gauge when the trigger is released and the unloader goes to bypass mode. Please help!?
Answer
the crank case it self is a two piece unit and there is a gasket there
