  2. Modification Overview • Production of the 009 began in 1989 and is current. • A lead free (LF) version was introduced in 2010. The leaded bronze parts were replaced with plastic or stainless steel.

  3. Single Access Cover Removal • Cover is o-ring sealed. • 009 cover has spring load from the RV spring. * Remove bolts while holding cover down. * RV Stem may come out with cover. • Lift cover straight off.

  4. Check Valve Removal • Check valve modules. • Modules sealed by o-ring and secured by a retainer. • Slide retainer straight out of body. • Modules can now be removed by hand or with a screwdriver flat.

  5. Check Seat Removal • Check seats are part of each module. • Check seats are attached to the cage with a bayonet type locking system. * Check spring is contained. * Hold the cage in one hand, push the seat inward and rotate counter-clockwise.

  6. Check Disc Replacement • Remove retaining nut from disc holder and replace rubber.

  7. Check Valve Reassembly Notes • Reassemble in reverse order. • Apply lubricant to o-rings. • If check retainer does not slide into place easily, make sure check valves are seated properly.

  8. RV Stem Removal • The RV Stem and spring are situated between the check valves and are free once the single access cover is removed.

  9. RV Seat Removal • Unless damaged, there is no need to remove RV seat. • The seat is pushed firmly into the body and is o-ring sealed.

  10. RV Rubber Replacement • The RV molded disc is on the lower stem. Simply unscrew the nut from the guide. * Replace the o-ring behind the disc. • The diaphragm is on the upper stem. Simply unscrew the stem cap from the stem.

  11. RV Reassembly Notes • Center the spring on the seat and insert the cover and stem assembly as a unit straight into the body. • Make sure that the lower guide on the RV stem goes through the guide hole in the seat. • If the cover will not press flat against body, the stem is crooked and must be realigned.
