Servicing the First and Second Check Valves
1.
Remove cover bolts and cover.
2.
Remove the retainer from the body bore. The check valve modules can now be
removed from the valve by hand or with a screwdriver.
3.
The check seats are attached to the cage with a bayonet type locking arrange-
ment. Holding the cage in one hand, push the seat inward and rotate counter-
clockwise against the cage. The seat, spring cage, spring and disc assembly are
now individual components.
4.
The disc assembly may now be cleaned and reassemble or depending on its con-
dition, may be discarded and replaced with a new assembly from the repair kit. O-
rings should be cleaned or replaced as necessary.
5.
Reassemble the check valve modules. Check modules are installed in the valve
body with the seats facing the valve inlet. The modules must be securely in place
before the retainer can be replaced.
NOTE: No special tools required to service Model 3000B.
