Sorry about all the confusion, it worked fine on the international. Doesn't seem to hit as hard on the belarus. Not sure what the pb valve is? And which nut shouldn't be tight? Lock nut on top or underneath the top of the ram? And yes I switched back to the quick attach hose, , ones up and down, but not with much strength. Thank you all for trying to help me out!

Springs for the HD8, HD10, and HD12 have different part numbers.

PB port is the port that has a large hex plug in it to make the valve an open center valve, a PB valve or a closed center valve. . Picture HD8-25. It is on the same end as the return port.

The cyl rod end top nut is the nut you tighten and then loosen 1/2 turn. Picture HD8-42 in the PDF

Check your valve relief and see if it is set for 1500 psi.

Hydraulic Requirements 3 - 4 GPM at 1500 PSI

Lubricate four guide blocks (A2) with oil
before each daily use and, if necessary,
between post installations.

At the beginning of each day, use the main
hydraulic control lever to cycle the drive ram up
and down 10 to 15 times, without impact with a
post or the ground, to 都eason the drive ram
return springs. Failure to follow this
recommendation can cause damage to the
springs.
