Solenoid Valve SV10 and SV11 Service (RM 6700-D Only)
Removal
Note: Solenoid valvesSV10 andSV11provideoilflow
to the reel motors of cutting units #6 & 7 (see Hydraulic
Schematics and Flow Diagrams in this section of this
manual).
Note: Read the General Precautions for Removing
and Installing Hydraulic System Components at the be-
ginning of the Service and Repairs section of this chap-
ter.
1. Make sure the area around the valve is clean before
removing the valve.
2. Disconnect the electrical connector from the sole-
noid valve.
3. Disconnect all hydraulic tubes and hoses.
4. Remove solenoid valve from the frame.
Inspection (Fig. 64)
1. Remove solenoid coil nut and coil.
Note: Use care when handling the cartridge valve.
Slight bending or distortion of the tube assembly can
cause binding and valve malfunction.
2. Remove the adapter, tube assembly, and spool from
the valve body. R ecord the spool orientation for correct
reassembly.
3. Cleanadapter,tubeassembly,spool,andvalvebody
in clean mineral spiritsto flush out contamination.Clean
and dry with compressed air.
CAUTION
Use eye protection such as goggles when using
compressed air.
4. Visually inspect all ports for damage to the sealing
surfaces, damaged threads, and contamination.
A. Contamination may cause valvesto s tick or hang
up.Contaminationcanbecomelodgedinsmallvalve
orifices or seal areas causing malfunction.
B. If sealing surfaces appearpitted or damaged, the
hydraulic system may be overheating or there may
be water in the system.

5. Lubricate new O-rings of seal kitwith clean hydraulic
oil and install.
6. Install adapter and spool in valve body.
7. Thread tube assembly carefully into valve body.
8. Installsolenoid coil. Apply ”Loctite242” or equivalent
to the threads of the coil nut and tighten to 15 in-lbs.
9. If problems still exit, remove valve and clean again
or replace valve.
Installation
1. Install solenoid to the frame.
2. Connect all hydraulic tubes and hoses.
3. Connect electrical c onnector to solenoid valve (see
Hydraulic Valve Solenoids in Chapter 5 - Electrical Sys-
tem).
