Disassembling and assembling PAHT and PAHT G 256-308

1. Push a screwdriver into the hole between

cylinder barrel and valve plate. Carefully

push downward the screwdriver so that it

makes a gap between cylinder barrel and

valve plate. Use this gap to put in another

screwdriver and loosen the valve plate

from the cylinder barrel.

3. Lubricate the new O-rings/back-up rings

and the liners in the cylinder barrel with

clean filtered water. Lower the valve plate

upside down on the cylinder barrel. Place

tool set) like on the picture. Screw the bolt

into the shaft of the cylinder barrel. Turn

the nut slowly clockwise. The valve plate

must slide carefully into the cylinder

barrel. Stop when the gap between

cylinder barrel and valve plate is 1-2 mm.
