Hi pressure pump

Hi All,my hi pressure washer stopped working,no pressure, it's a Annovi Reverberi Mdl RMV 2.5G27D I have disassembled the wetend of the pump and everything is clean and free,my only question is there are 3 stainless steel pistons on the opposite end ,should I be able to push them in?
Thanks Geo

If you are pushing from the outside in, no, they won't push in because the spring is already holding them in. They should move as you rotate the engine though.

So if I remove the wet end and reinstall the pump and crank the motor with the rope I hold see them move .

I usually just start about halfway and fine tune one way or the other depending on if it's chugging too hard before it unloads when I release the handle. If so, lighten up on the spring tension a little.
