SECTION 6 - OPTION NOTES AND INSTRUCTIONS
6.10
6.14. REMOTE PILOT OPERATED CHECK VALVE PACKAGE
For option # 8L1430 (JIC) & 8L1432 (NPT)
1. Locate hydraulic lines coming from ports “I” and “F” on hydraulic block.
2. Trace lines back to just behind the slow moving emblem where the lines tee off.
3. Install pilot check valve (8L0036) in those lines. Lines coming from summers block will attach to ports
v1 and v2.
4. The lines coming from cylinders will route to c1 and c2 and will attach to block with tee.
5. Care must be maintained to insure that the “I” hose will still route to the rod side of the cylinders
through the V1-C1 or V2-C2 path. The other “F” hose will go to the remaining port series either 1 or 2
so we don’t have hose crossing.
6. Tighten all fi ttings and reinstall the slow moving emblem.
7. Locate the pressure relief cartridge in the summer’s hydraulic block and replace it with new one from
package.
8. Locate cartridge “F” and replace it with one of the new cartridges in the kit.
9. Replace the original coil on “F” with one of the new e coils in the package.
10. Hook up coil to original wire using wetherpack to deutsch adapter harness if required.
11. Locate cartridge “I” and replace it with remaining new cartridges from the kit.
12. Use care when removing existing cartridge because there is an orifi ce under the cartridge that can fall
out. Replace the original orifi ce with an offset orifi ce from the package.
13. Reinstall the “I” cartridge and replace coil with new e coil.
14. Hook up coil using wiring adaptor.
15. Test the system for proper operation in full extension or full retraction of part 1 cylinders.
16. Inspect for hydraulic leaks
17. Verify the boom drift to forward position is gone and boom remains where it was left by operator.
These instructions should help you install the pilot operated check valve package. The pilot check valve will
prevent the booms from moving forward while sprayer is in use. They will also permit the relief valve to func-
tion properly if the booms have not been lifted from the transport cradle prior to any unfolding operations. The
relief valve will protect the eye bolts from being broken during unfolding. The relief valve will be isolated
from the rest of the circuit during spraying operations and boom drift should be eliminated.
