Wiz or anyone,
Ive got a Rk-21 and the problem Im having is pump pulsation. Not a lot but enough to be annoying. The unit has a general 2021 belt drive. 3000/5.5. If you put your foot on the hose while under pressure you feel some pulsation. Ive replaced packings and check valves and orings and still get pulsation. I have other machines with this same pump and they dont do this. It does it at all psi settings, less noticeable at 3000psi though. Any tips, hints or tricks? I cant figure it out. Im creating a bald spot on this one so please help before I run out of hair.
