3 - 5
If pressures are not as specified in Figure 3-5, check for:
1.
Improper pilot supply pressure.
2.
Malfunctioning solenoid valve.
3.
Leaking pressure hoses or fittings.
4. Restriction in pressure hose or manifold port.
LINE-IN Pressure Check
With the engine shut off, connect a 1000 psi pressure
gauge in line on the RI hose at the logic control manifold.
Start the engine and measure pressure with the control
lever in the
LINE-IN
position. Pressure should be as
specified in Figure 3-5.
If the line in pressure is not as specified in Figure 3-5,
check for:
1.
Improper pilot supply pressure.
2.
Malfunctioning control lever.
3.
Leaking pressure hoses or fittings
4. Restriction in pressure hose or manifold port
LINE-OUT Pressure Check
With the engine shut off, connect a 1000 psi pressure gauge
in line on the RO hose at the logic control manifold. Start
the engine and measure pressure with the control lever in
the
LINE-OUT
position. Pressure should be as specified
in Figure 3-5.
If the line out pressure is not as specified in Figure 3-5,
check for:
1.
Improper pilot supply pressure.
2.
Malfunctioning control lever.
3.
Leaking pressure hoses or fittings.
4. Restriction in pressure hose or manifold port.
Valve Setting Procedures
Brake release valve
Connect a 1000-psi gauge at the brake test port and
another 1000-psi gauge at the RI (reel-in) test port. At
engine idle, slowly meter control lever into the reel-in
position while monitoring both gauges. Increase control
lever stroke until the RI gauge reaches 130-150 psi; brake
pressure should jump to full pilot supply pressure (275-650
psi) at this point. If the brake pressure jumps up before
the pressure at RI reaches 130-150 psi, adjust valve in
until the increase occurs at 130-150 psi. Similarly, if the
spike does not occur until the pressure at RI is more than
130-150 psi, adjust valve out until it occurs at 130-150 psi.
Pilot supply reducing valve
