4.7 HOSE ROUTING – BOOM TO VALVE
•
Connect the RED colour coded hoses to the green boom hoses at the base end of the boom.
•
Route the hoses through to the pump compartment towards the control valve following the existing
hose routing from the boom end.
•
Trace the hoses from the quick coupler cylinder right through to the end where they connect to the
valve to determine the correct hose for each port position on the valve.
•
Connect the hose ends to the control valve ensuring that they are connected to their respective port
positions relative to the cylinder.
•
Cable tie Boom to Valve hoses to existing hoses where appropriate and coil any excess hose in the
pump compartment. Ensure that the hoses are not bound up or under any strain.
•
Tighten all hose joints and fittings between the lower boom end and the control valve.
4.8 HOSE ROUTING – VALVE TO PUMP / TANK
•
Using the BLACK colour coded hoses connect the hose ends to the valve ports marked P (Pump)
and T (Tank)
•
Utilizing a “TEST PORT” on the pump that delivers hydraulic pressure to the crowd cylinder (see 4.3
above) connect the hose from the “P” port to the test port.
•
Locate an existing “RETURN” hose on the main return manifold or hydraulic tank. Disconnect the
existing hose and install a tee fitting.
•
Reinstall the existing hose onto one end of the tee and then connect the new return hose from the
control valve “T port to the other end of the tee.
•
Cable tie hoses to existing hoses where appropriate and coil any excess hose if required. Ensure
that the hoses are not bound up or under any strain.
•
Tighten all hose joints and fittings between the control valve and the pump and tank.
NOTE 1: Wedgelock has endeavoured to supply the majority of the fittings required to carry out a complete
install of an I-Lock Coupler, however due to the vast array of different carrier machines, fitting types and
port sizes, not all circumstances may be accounted for. In instances where the fittings supplied do not
match the port size or the type of carrier machine please contact your nearest machinery dealer or
hydraulic fittings provider for the additional appropriate component(s).
