Z1361 Service Guide
Step 1: Shutting Off the Water Supply to the Hydrant
Locate the supply shut-off valve and rotate until water
supply is off.
Step 2: Removing the Face Nut and Adjacent Components
Using crescent wrench or 1-1/2 inch open-end wrench,
remove the face nut (4) from head (1) by turning counter
clockwise.
Step 3: Removing the Internal Operating Assembly
The internal operating assembly (5-11 and 17) can be
removed by gripping the square end of the operating screw
(5) with a pair of pliers and pulling straight out.
If the operating screw “O” ring was not the reason for
service - skip to step 5.
Step 4: Replacing the Operating Screw “O” Ring
Remove the operating screw (5) from operating coupling
(7) by turning clockwise and slip the old “O” ring (6) off, and
replace with new “O” ring (6). Reinstall operating screw (5)
into operating coupling (7) by turning counter clockwise.
(NOTE: Lubricate the operating screw (5) threads and the
“O” Ring (6) with Lubriplate FGL-2 if needed.)
If the hydrant shutoff washer and washer guide “O” rings
were not the reason for service - skip to step 8.
Step 5: Replacing the Hydrant Shutoff
Washer and Washer Guide “O” Rings
Remove #10 - 24 NC x 3/8 screw (11) using a flat
screwdriver and turning screw (11) counter clockwise,
remove washer (10) and replace with new washer (10) and
new screw (11) turning screw clockwise until tight. Remove
old “O” rings (17) and replace with new “O” rings (17).
(NOTE: Lubricate the “O” rings (17) with Lubriplate FGL-2
if needed.)
Step 6: Replacing the Internal Operating Assembly
There is a flat or a V-notched boss inside of the hydrant
head (1) that keeps the operating coupling (7) from rotating
when hydrant is turned on and off. With operating screw
(5) turned counter clockwise into operating coupling (7)
until it stops, and making sure that a flat side or corner
of operating coupling (7) lines up with appropriate boss,
reinsert the internal operating assembly into the hydrant.
Step 7: Replacing the Face Nut
Insert face nut (4) into head (1), and rotate clockwise until
hand tight, then using a crescent wrench or 1-1/2 inch open
end wrench, snug nut (4) tight.
Step 8: Turning On the Water Supply
Locate the water supply shut-off valve and rotate until water
supply is on.
