4.5.6.4 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 13. A second
bead of sealant 0.060" - 0.090" (1,5 mm - 2,3 mm) in
size should then be applied in the shallow groove.
See Figure 14.

Inspect the new wear plates (3) and remove any
scratches or raised edges with very fine sandpaper or
steel wool. Position the smoothest side of the wear
plate on the sealing surface, being careful to align the
holes with those in the IRON.
4.5.8
Position the support rings (50) & (51) over the holes
in the wear plates (3) and install the new hex head
screws (4) and locknuts (5) provided, securing them
finger tight.
Caution
To prevent excessive warping of the wear plate and
to endure a good seal, the following torque tightening
procedure must be followed.
4.5.9
For each wear plate being replaced, the torque
tightening instructions are as follows:
Note: The torque of the screws & nuts (4) (5) that attach the wear
plate (3) to the mounting flange (1), reaction plate (30) & pressure
plate (13) is a four step process.
(a)
For the first 16 screws, bring the initial torque of
each screw up to 33% of the torque value shown in
Table 2 using the tightening sequence shown in
Figure 15. Install and torque the remaining screws
in any reasonable crosswise pattern to 33% of the
torque value shown in Table 2.
(b)
Repeat the sequence of torque tightening on the
first 16 screws as shown in Figure 15 and bring each
screw up to 66% of the torque value shown in
Table 2. Torque the remaining screws in any
reasonable crosswise pattern to 66% of the torque
value shown in Table 2.
(c)
Repeat the sequence of torque tightening on the
first 16 screws as shown in Figure 15 and bring each
screw up to 100% of the torque value shown in
Table 2. Torque the remaining screws in any
reasonable crosswise pattern to 100% of the torque
value shown in Table 2
(d)
Finish torque tightening by selecting a starting
position (usually at the 12 o’clock position) and check
the 100% torque of each screw going in a sequential
clockwise or counterclockwise rotation. Mark or
highlight screw head or nut & shank after final torque
check as a visual indication that the screw/nut has
been tightened to specification shown in Table 2.
Caution
Allow the Loctite Superflex
®
#596 Sealant 24 hours
to completely cure before performing the following
leak test procedure
