entire length of the piston rod (17) threads. Sealant
must be allowed to cure for a minimum of 12 hours
before use. Screw the rod through the piston and
spacer (44) and into the piston nut (12). Torque the
nut to 95-100 ft-lb (129-135 N•m).
3. With the inlet housing (15) turned upside down,
install the balls (5) and the gaskets (7*).
COMPONENT RUPTURE HAZARD
The relief valve seat (6) must be installed at the fluid
inlet, as shown in F . 6. The relief valve reduces the
