seals (26, 30, 31), and the thrust bearing (24). Reinstall all components in reverse order as
disassembly instructions.
Replacing the Inlet Swivel Assembly:
 Order repair kit SWMF-RK4 for 1-1/2" NPT inlet swivel (BL064, BL068, BL072,
BL072NS) or SWMF-RK5 for 1-1/4" NPT inlet swivel (BL062, BL066, BL066NS) or
SWMF-RK6 for 1-1/2" BSPP inlet swivel (BL072-BSPP).
 Order repair kit SWMF-RK42 for 2" NPT inlet swivel (BL920 & BL919) or SWMF-
RK52 for 1-1/2" NPT inlet swivel (BL918) or SWMF-RK62 for 2" BSPP inlet swivel
(BL924) or SWMF-RK72 for 1-1/2" BSPP inlet swivel (BL917).
 Secure the ball nozzle in a bench vice with the inlet end pointing vertically up; this will
prevent loose internal components from falling out.
 Then remove the inlet swivel assembly; DO NOT use a pipe wrench, which can cause
distortion of the swivel body (20) and possible leakage. A spanner or crescent wrench is
recommended. Using a pipe wrench WILL VOID WARRANTY.
 Install replacement inlet swivel; apply a removable thread locker such as Loctite 242 to
the male threads of the swivel body (20) and thread into the body (1). Use a crescent
wrench (NOT a pipe wrench) to tighten until swivel body (20) bottoms out against ball
nozzle body (1).
Changing the Check Valve Pressure Setting:
Repair kit BL-RK11 / BL-RK112 provides to possibility to reset the check valve pressure
setting from the standard 3psi to 5psi.
 Remove the spout adapter (48A/48B) (or swivel nut adapter [46]) from the body outlet
end (1).
 Remove the o-ring seal (43) and the check valve "cartridge" (36, 37, 38, 39A, 40, 41, and
42).
 Decrease the tension from the check valve cartridge by slightly compressing the spring;
carefully remove the retaining ring (41); check valve cartridge will come apart.
 Replace the old spring (39A – set at 3psi) with the new spring (39B – set at 5psi).
 Reassemble the check vale cartridge in reverse order and secure by reinstalling the
retaining ring (41).
 Insert check valve cartridge into body outlet end; insert new o-ring seal (43)
provided in repair kit into groove in check valve bridge (40); apply a removable
thread locker such as Loctite 242 to the male threads of the spout adapter
(48A/48B) (or swivel nut adapter [46]) and thread into the body (1). Use a wrench
to tighten snug; do not over tighten.
