I hated to break up the pump that I had taken off to fix it, as it had a good pressure, in the end, I did it because the long wait to rise annoyed me.
A big press can do anything.




[edited to improve translation]
I do not know what you mean by "sugar", maybe polishing?, also not sure about "steamer"?When I opened the pump the intention was to check the valves, the pump had good pressure despite a lot of worn discs, a valve. I turned them on to the other side that was straight and I just wiped them up in a small amount of sugar, the head where the valve valves were only slightly processed by the steamer, did not have the need to grind as the bearing.
