HYDRAULIC INSTALLATION
NPK HYDRAULIC INSTALLATION KITS
NPK Hydraulic Installation Kits are available for virtually all compatible backhoe and
excavator models. The kits include all parts and complete instructions for the hydraulic
installation, including valves, electrical or manual controls, hoses and fittings, boom and
stick piping and clamps.
See your NPK dealer for details or call NPK direct at 1-800-225-4379.
HYDRAULIC LINES
Typically, the pressure line is arranged on the left side of the boom and the return line is
on the right side.
SHUT-OFF VALVES
Most NPK Hydraulic Installation Kits use two shut-off valves (k4) on the dipper stick (k1)
of the carrier. These valves control the hydraulic oil going to the pressure side (m3) and
returning (m4) from the Compactor/Driver. (NOTE: Some smaller carriers utilize a
check valve on the return side.)
