Check Valve Service
The ProPass control manifold includes four (4) check
valves used for circuit control. Check valve location is
identified in Figure 37. Remove check valves from mani-
fold for cleaning or replacement. Replace seal kit on
check valves if removed from manifold. Torque check
valves from 12 to 14 ft- -lb (16 to 18 N- -m) when in-
stalling them into manifold.
NOTE: Check valves CV3 and CV4 are not used in the
ProPass 200 hydraulic system.
Refer to Hydraulic Schematics in this chapter for circuit
location of check valves.
Orifice Service
The control manifold includes four (4) orifice fittings that
thread into specific manifold ports. Access to these ori-
fice plugs requires removal of the manifold plug. Orifice
locations are shown in Figure 38.
NOTE: Orifice fitting ORF3 is not used in the ProPass
200 hydraulic system.
Refer to Hydraulic Schematics in this chapter for circuit
location of the orifice fittings.
