Note: The ports on the manifold are marked for easy
identification of components. Examples: BV is the deck
circuit braking valve and P1 is the gear pump connection
port. (See Hydraulic Schematics to identify the function
of the hydraulic lines and cartridge valves at each port
location).
SRV Cartridge Valve (Fig. 92 and 93)
1. Make sure the manifold is clean before removing the
cartridge valve.
2. Remove nut securing solenoid to the SRV cartridge
valve. Slide solenoid off the valve.
IMPORTANT: Use care when hand ling the cartridge
valve. Slight bending or distortion of the stem tube
can cause binding and malfunction.
3. Remove SRV cartridge valve from port R1 using a
deep socket wrench.
