Refer to Figures 1 & 2 for part locations. 1. For TitanHT™/MXT models only, using a permanent marker, make a reference mark on the pressure adjusting nut and the pod body to show factory set location. 2. Remove the stator screws using the hex key provided by loosening 1/4 turn at a time in a sequential fashion (for 3 stator screws) or in a diagonal fashion (for 4 or 5 stator screws). 3. Remove the stator and stator face assembly (if present). The stator face assembly may remain on the stator. 4. Remove the stator ring screws (if present). 5. Remove the stator ring (if present). 6. If valve contains an isolation seal, remove it and replace with new seal if it appears damaged. 7. Pull the rotor seal off the pins. If needed you may use a small flathead screwdriver to pry off the rotor seal. 8. Mount the new rotor seal with the grooves facing the stator. The pins on the shaft assembly fit into the mating holes in the rotor seal only one way (see Figure 3). 9. Replace the stator ring (if present) so that the pins on the ring enter the mating holes in the body. 10. Replace the stator ring screws (if present). 11. Mount the new stator face assembly (if
included) on the stator. If the assembly has 3 pins it can mount only one way. If the assembly has two pins, it is symmetrical and may be installed in either orientation. 12. For valves with no stator face assembly, clean the stator sealing surface by rubbing approximately 20X with isopropyl alcohol on a soft cloth. For TitanHT valves with the SupraLife™ material combination more rigorous cleaning of the stator surface is essential for proper sealing, use of a cotton swab with isopropyl alcohol and a microscope is recommended. 13. Replace the stator and stator face assembly (if present) on the valve so that the pin in the stator ring enters the mating hole in the stator. 14. If you are rebuilding a TitanHT/MXT make sure that the marks you made on the pressure adjusting nut and the valve body line up. 15. Replace the stator screws. Tighten each screw a 1/4 turn at a time to keep the stator and rotor seal surfaces parallel. For valves with 3 screws tighten sequentially. For valves with 4 or 5 screws tighten in a diagonal fashion. For stator screw torques see www.idex-hs.com/products/rhebuildkit.
