If nubs in the water cavity are severely cor-
roded, wear plates may not be properly sup-
ported. 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. These surfaces
should be free of nicks and scratches to prevent
leaks. Minor nicks and scratches may be filled with
Loctite Superflex
®
#596 Sealant during assembly.
4.6.5
Apply a uniform bead of Loctite Superflex
®
#596 Seal-
ant in the grooves of the pressure plate, reaction
plate(s) and/or mounting flange. Recommended 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 pro-
cedure. 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 approxi-
mately 10 minutes. The wear plate must be
fastened to the mating component within 10
minutes of applying 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 seal-
ant, 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.
