Angier,

I=E2=80=99= m not sure what you mean by this.

If it is a= cylinder, don't forget about the sealing washer under the piston nut.=E2=80= =9D

OK, hear=E2=80=99s a dumb question for y= ou=E2=80=A6.

I have no external leaks so, i= f there is an internal leak in one of the actuators(I mean cylinders for gea= r and doors, , and as the high pressure begins to drop, should we not see a c= orresponding
increase in pressure on the low side?
As for the dump valve, I trashed that which came wit= h the kit in favor of higher quality. I don=E2=80=99t think I have a dump va= lve issue.

Hoping this does not screw up my= plans for KRDM.
