cam assembly slightly downstream so that the clapper is

now parallel to the valve body. Now bring the cam assembly

through the check retaining wall. Leave the cam assembly

clapper parallel to the valve body. Pull the cam assembly

through the access port.

Using a

" nut driver or a piece of small diameter pipe,

place on the cam arm torsion spring and move away from

and around the torsion spring retaining bracket so as to

relieve the torsion spring tension. (See Figure 4.) This will

allow the cam arm to move freely, enabling you to inspect

the clapper face and cam seat. Thoroughly clean the seat

area and clapper sealing surfaces, cam arms, and O-rings

for damage, nicks, and debris. If damaged, install a new

check assembly O-ring, or washer, shutoff disk.

Before reinstallation of check assembly, thoroughly clean O-ring

groove and lubricate O-ring with F.D.A. approved lubricant.
