Carefully pull stream straightener (8) out of nozzle base using needle nose pliers. 9. To remove stator (15), insert screwdriver blade between stator and drive assembly housing (13) and pry apart. Note: A small notch for screwdriver blade insertion is provided on edge of stator. 10. Thoroughly clean and inspect all parts. Replace parts as required. Note: If changing nozzle to a different size, appropriate stator must also be installed to ensure proper rotation speed and coverage. WARNING POSITIVELY SHUT OFF WATER SUPPLY AT SOURCE PRIOR TO REMOVING VALVE ASSEMBLY. BLEED ALL PRESSURE FROM SYSTEM INCLUDING CONTROL TUBES. FAILURE TO DEPRESSURIZE SYSTEM PRIOR TO SNAP RING REMOVAL COULD CAUSE VALVE MECHANISM TO EJECT FROM SPRINKLER BODY UNDER PRESSURE RESULTING IN POSSIBLE SERIOUS INJURY TO PERSONNEL. 11. To remove valve assembly, squeeze ears of snap ring together with snap ring pliers (P/N 995-07) and remove snap ring from sprinkler body. (See Figure 4). CAUTION If snap ring is difficult to remove, there may be residual water pressure in the system. Recheck the water supply to insure it is turned off and all pressure has been totally eliminated before removing the snap ring and valve. 12. Use valve removal tool (P/N 995-08) to remove valve assembly from base of sprinkler body. Valve Removal Tool is inserted into sprinkler body and pushed through valve ribs to the underside of valve. A slight twist will lock tool to valve enabling removal by pulling straight up and out. (See Figure 5.) NOTE: If valve removal tool is not available, use snap ring pliers to grasp rib of valve assembly and pull up and out of sprinkler body. 6 13. To reinstall valve assembly with snap ring and to prevent damage to the communication tube in sprinkler body, use valve insertion tool (P/N 995-11). Valve insertion tool will automatically line up valve assembly with sprinkler body communication tube and correctly seat the snap ring. (See Figure 6). NOTE: It is possible to install the snap ring backwards (upside down). See inset in Figure 6 to insure that snap ring is installed in the correct manner. Figure 4 Using Snap Ring Pliers to Remove Snap Ring Figure 5 Using Valve Removal Tool to Remove Valve Assembly Figure 6 Using Valve Insertion Tool to Install Valve Assembly with Snap Ring Pliers 7 Servicing Pilot Valve Assembly Note: Assure water supply to sprinkler is positively shut off and all residual pressure has been bled. If sprinkler is pressurized, main valve will open when the pilot valve control tube is disconnected. Refer to Figure 7 for the following procedure. 1. Carefully remove turf and soil from side of sprinkler to expose pilot valve and control tubing. 2. Remove two retaining screws from pilot valve housing. 3. Pull pilot valve assembly away from sprinkler body and cut control tubing just below tube retainer. Unless pilot valve has been previously removed, control tubing length will be sufficient for re-connection. 4. Remove tube retainer and remaining piece of control tubing from valve body fitting. 5. Remove solenoid (1) or NC adapter (2) by turning it counterclockwise. 6. Pull pilot valve body assembly (4–12) out of housing. 7. Remove diaphragm assembly (12), piston (11) and spring (10). 8. Remove selector (7) and plunger assembly (5 or 6). Selector retains plunger in body. 9. Thoroughly clean and inspect all parts. Replace damaged parts as necessary and reassemble in reverse order. 8 Figure 7 Pilot Valve, Current 1 4 9 12 10 8 11 3 5 6 2 7 1 4 9 12 10 8 11 3 5 6 2 7 Item No. Part No. Nomenclature Quantity Per Assy. 1 89-1905 Solenoid, Pilot Valve & Valve 1 2 89-6005 Adapter, Pilot Valve, NC 1 3 89-0001 Housing, Pilot Valve 1 4 360-0220 O-Ring, .070" x .551" x .691" 1 5 35-9993 Plunger Assy., Elec. 1 6 89-6003 Plunger Assy., NC 1 7 - - - - Selector (See Service Parts and Assemblies below) 1 8 1-2035 O-Ring, .070" x .114" x .254" 1 9 89-6004 Body Assy., Pilot Valve 1 10 35-9970 Spring, 50 lbs., Black 1 10 35-9971 Spring, 65 lbs., Green 1 10 35-9972 Spring, 80 lbs., Red 1 10 35-9973 Spring, 100 lbs., Blue 1 11 89-0029 Piston 1 12 89-0005 89-0009 89-0010 89-0011 89-0012 89-3918 89-3919 89-7125 89-7126 89-0998 89-0999 89-1000 89-1001 102-0343 Diaphragm Assembly SERVICE PARTS AND ASSEMBLIES Pilot Valve Assy., 50 lbs., Elec.
