YDRAULIC
Three hydraulic connections are required to the pump set. Two lines connect the main
steering lines, and the third line to the header tank of interconnect line which compensates
for thermal expansion of the oil and self bleeds air from the system.
Flexible hose with a pressure rating of minimum 1500 psi working pressure is recommended
for the steering line connections. Flexible hose (min. 250 psi pressure rating) is
recommended for the fill/interconnect line. The hose should be minimum 3/8” inner
diameter.
