Introduction
Read all of the instructions before proceeding.
Refer to Kadant Johnson assembly drawing for part
identification and to drawing A37640 for torque
specifications. For easy identification, parts used in
individual steps are often accompanied with their
position in the assembly drawing [e.g. gasket (8B)].
Tighten all fasteners in a star pattern. Certified
drawings are available upon request. Dimensions
are for reference only and subject to change.
Safety
This safety symbol alerts you to risk of death or injury if the instructions
are not followed. In all steps, death or injury may result if the machine is
not de-energized, depressurized, cooled, and stopped. Death or injury
may occur if the product is operated with a fluid type or at a pressure,
temperature, or speed that do not meet its specifications. Death or
injury may occur if heavy parts and pinch hazards are not handled
properly. Follow your company’s safety procedures.
Step 1
Disconnect the piping and anti-rotation device.
Remove the head.
Equipment must be cooled and free of pressure.
Step 2
Remove the pressure plate and split rings.
Important: Mark the end of the horizontal pipe
where it passes through the pressure plate or
measure and record the distance it is protruding
out. Refer to either during installation.
Note: In some instances a horizontal pipe handling
tool will be needed. Contact Kadant Johnson if one
is needed.
Step 3
Loosen and remove the nipple flange and slide the
rotary joint away from the journal. Remove the
metal gasket (8Q) from the journal flange and
discard. Remove the split wedges and nipple flange
and save for reuse.
Step 4 - SERVICING THE ROTARY
JOINT
Remove the wedge plate and assembly plate by
loosening the two cap screws (31A).
Spring force present during wedge plate removal.
Step 5
Remove the front guide and assembly consisting of
the nipple, spring shoulder, spring, and seal ring.
Note: The spring shoulder may be stuck on the
nipple. Separate the two parts.
Note: ELS rotary joints that are 3 1/2" and larger, the
front guide is contained in the assembly plate and
is removed with it.
Step 6
Separate the wear plate form the body. Remove the
back guide by removing the retaining ring.
Step 7
Discard the seal ring, gaskets, guides, and O-rings.
Inspect and clean all gasket, O-ring, and sealing
surfaces. Replace any damaged parts.
Step 8
Install a new back guide into the wear plate and
secure with the retaining ring. Using a new gasket,
install the wear plate on the body.
Step9
Turn the rotary joint upright and install a new seal
ring, with the concave side facing outward. Install
the nipple into the body followed by the spring.
Step10
Install a new O-ring into the spring shoulder. Install
over the nipple by aligning the keys with the spring
shoulder keyways.
Step11
Install the front guide over the nipple with the two
pin holes facing outward.
Step12
Install a new O-ring into the assembly plate and two
new O-rings into the wedge plate. Using two new
gaskets, install the assembly plate and wedge plate
while lining up the pins with the corresponding
holes in the guide.
Step13 - REINSTALLATION
Slide the nipple flange over the rotary joint nipple
with the taper facing out. Place the split wedges
into the recess of the nipple. Slide the nipple flange
over the wedges.
Step14
Place metal gasket into the journal flange. Lift the
rotary joint up, slide over the horizontal pipe and
into the journal flange. Secure to studs with nuts. An
even gap of 1/8" to 3/16" (3 to 5 mm) should remain
in between the journal flange and nipple flange.
Step15
Place the split rings into the wedge plate. Install the
pressure plate over the split rings and hand tighten.
Position the horizontal pipe as it was in step 2.
Tighten cap screws evenly to 8 ft-lbs (11 Nm). Tap the
pressure plate with a soft-faced hammer to seat the
split wedges. Tighten cap screws evenly to 16 ft-lbs
(22 Nm).
Step16
Install the head using a new gasket. Reinstall the
piping and anti-rotation device.
