Cap Removal Tool
GENERAL DISASSEMBLY
1. REMOVE THE SPRINKLER from the ACME thread of
the quick change adapter.
2. SEPARATE THE CAP FROM THE BODY by squeezing
the release points (the words SQUEEZE) while
turning counter-clockwise. For easy removal, use
the #10689 Cap Removal Tool. Position the tool (as
shown on the right) to apply pressure to the words
SQUEEZE.
3. Use the #12260 2TN Nozzle Removal Tool to
REMOVE THE 2TN NOZZLE from the body. Place
the tool at the top of the R2000WF body and press
down. The nozzle should easily pop out.
WARNING: Always use the #12260 tool to remove a 2TN nozzle from a
R2000WF Rotator. Never use a stick, rod, or any other object to push on
the outlet of the 2TN nozzle to remove. This can easily damage the plate
bearing surface and cause rotation failure.
4. REMOVE THE PLATE by placing your fingers in the
open space in the cap (between the washer and
plate). Pull towards you until the plate pops up
away from the cap.
5. REMOVE THE MOTOR from the cap by fitting the
Motor Removal Tool #12215 onto the top of the cap.
(1) Press on the outer ring of the motor removal
tool so it fits tightly against the cap. (2) Press on
the inner circle of the tool so the motor disengages
from the cap. Gently push the motor from the top to
completely remove it from the cap assembly.

GENERAL ASSEMBLY
1. SELECT THE NEW PARTS — nozzle, plate and/or motor that will be used in the assembly.
Always be sure the nozzle size is recommended for the plate and the motor. See graph
on right.
2. While holding the cap in one hand,
INSTALL THE MOTOR by first setting the
diffuser in place (small teeth against the
ridges in the cap) and topping it off with
the washer. Direct the motor into the hole
of the cap assembly. Align the hole of the
Motor Assembly Tool (the disc that ships
with part #12215) on the shaft of the
motor and snap motor into place.
3. Next, ASSEMBLE THE PLATE TO THE CAP
ASSEMBLY. Place the cap assembly in
one hand and the WF Plate in the other.
Orient the two components so the flats
of the motor shaft and plate are parallel
as shown below. Gently push the plate
onto the shaft. The plate is correctly
installed once you have felt two distinct
“clicks” as you push the plate on. Do not
continue pushing after you have felt the
plate snap into place. Damage to the plate
and/or other parts may occur, resulting in
unsatisfactory sprinkler operation.
2. CONNECT THE CAP/PLATE ASSEMBLY TO
THE BODY by holding the body in one
hand and fastening the cap/assembly
with a clockwise turn of the other hand.
3. PLACE A 2TN NOZZLE INTO THE BASE OF
THE WF BODY with the small end of the
nozzle pointed towards the cap.
4. PLACE A QUICK CHANGE ADAPTER INTO THE
BASE OF THE BASE OF THE BODY and turn
clock-wise. Confirm that there is a o-ring
in place. Assembly is now complete.
