XII. Reassembly
(For parts identification refer to Figures 1 to 4)
1. Before reassembly, all parts should be cleaned.
All burrs on guiding surfaces should be carefully
removed.
2. Put a small amount of KOPR-Kote™ on the
spindle tip and on the lower spring washer
bearing. Thread the disc on the spindle and
assemble spring and spring washers on the
spindle.
3. Insert disc, spindle, spring and spring washer
assembly into the bonnet.
4. Assemble adjusting ring to base (top of
adjusting ring to be flush with seat). Place a new
bonnet gasket on the base.
5. Place a small amount of KOPR-Kote™ on the
ball end of the adjusting screw.
6. Holding bonnet and spindle (so that disc will not
drop) install bonnet assembly to base. Tighten
bonnet on base with strap wrench.
7. Assemble adjusting screw and reestablish
spring compression by first turning down the
adjusting screw to take out all play and then
add the same number of turns that it took to
relieve the compression when the valve was
disassembled.
8. Reestablish position of adjusting ring as follows:
a. Using a pointed tool, turn the adjusting ring
to the right slowly, thus raising the ring until it
touches the disc.
b Then, counting the notches, turn the
adjusting ring to the left, thereby lowering the
ring, until the original position is established.
9. Test valve per instructions outlined under
“Testing” (Section XIII).
