Recently overhauled OD when testing the pressure, it measured 500 to 550
psi on the gauge.The book says it should be 470 to 490 PSI and drops about
80 PSI when engaged or disengaged and jumps back up to 470 PSI very
quickly.
Question is " should I be concerned about the high numbers I am
experiencing ?

THANKS for your input

Dave

Those higher pressures show a healthy OD and you are probably using=0Ath=
e modern rubber O-rings rather than the steel originals. However,=0Aone=
 thing to check is the bleed down-release of pressure. If after=0Astoppi=

rked the lever a few times it would bleed out. If that does not=0Ahappen=

 function properly. If left unattended, the unit will not=0Acome out of=
