I just got gone with a 4020 PS. When it cam in, PTO pressure was just 53 PSI.
I posted on here about it last fall.
Don't know if anyone before me tried to correct pressure by adding shims to the pressure regulating valve.
Problem was seal wring was in wrong groove, got it back together, and now have 166 PSI, book calls for 150 PSI.
Would you guys leave it as-is, or take shims out to get it closer to factory "spec.", is "more better" or is there a downside to the extra pressure?
Thanks for any opinions on this.
