Follow manufacturer’s instructions and
proper safety precautions for
application of epoxy coatings.
If nubs in the water cavity are severely
corroded, wear plates may not be prop-
erly supported. Replace the pressure
plate, reaction plate or mounting flange,
if necessary.
4.6.4
Clean and completely dry the sealing surfaces
at the I.D. and O.D. on the pressure plate (14),
reaction plate(s) (31) and mounting flange (2).
These surfaces should be free of nicks and
scratches to prevent leaks. Minor nicks and
scratches may be filled with Loctite Super-
flex
®
#596 Sealant during assembly.
4.6.5
Apply a uniform bead of Loctite Superflex
®
#596
Sealant in the grooves of the pressure plate,
reaction plate(s) and/or mounting flange. Rec-
ommended bead diameter is 0.060" - 0.090"
(1,5 mm - 2,3 mm) for all sizes except for size
48WCB2. For size 48, refer to procedure
4.6.5.1 for proper sealant application proce-
dure. For all other sizes, skip to section 4.6.6
after application of sealant.
Loctite Superflex
®
#596 Silicon Sealant
will begin to set up and skin over in
approximately 10 minutes. The wear
plate must be fastened to the mating
component within 10 minutes of apply-
ing the sealant.
4.6.5.1
The 48WCB2 incorporates a dual groove for
both the Superflex
®
#596 Sealant and an
O-ring. An initial bead of sealant .030"-.060"
(0,7 - 1,5mm) in size must be applied to the
bottom of the deep groove in order to hold the
O-ring in place. See Figure 14.
4.6.5.2
Install the O-rings (I.D. and O.D.) on top of
the sealant, working them into position so that
they lay flat in the bottom of the groove. See
Figure 15. A second bead of sealant .060"-.090"
(1,5mm - 2,3mm) in size should then be applied
in the shallow groove. See Figure 16.
