Servicing Sprinkler Mechanism and Valve Assembly

(Refer to Figure 8 for the following procedure.)

1.Remove rubber cap plug (1) if installed.

2.Remove machine screw (2) and cap (4).

3.Using snap ring pliers (P/N 995-07), remove head snap ring (11).

4.Grasping nozzle base (9), pull sprinkler mechanism out of body.

Note: Due to O-ring seal compression between drive assembly and body, considerable resistance may be felt when removing sprinkler mechanism.

5.Unhook and remove retraction springs (6) from spring strap (5) and spring collar (14).

6.To remove nozzle base assembly, hold riser and riser pliers (P/N 995-17) and turn nozzle base assembly counterclockwise.

7.Using appropriate size end wrenches, turn nozzles counterclockwise to remove from nozzle base.

8.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
