1. Check liner for cracks and squareness. Wipe the inside of liner with a damp rag or paper towels taped to a stick or handle. This removes dust and adds some moisture which helps the Gorilla Glue or Elmer’s Glue-All Max to cure properly.
2. Dry-fit each of the grains into the case and make sure they slide easily inside the case. If not, sand lightly until they do.
3. Apply Gorilla Glue or Elmer’s Glue-All Max to the outside surface of the forward (uninhibited) grain and install in the nozzle end of liner with a twisting motion.
4. Install the first grain spacer O-ring, placed against the end of the forward grain.
5. 
6. Apply Gorilla Glue or Elmer’s Glue-All Max to the outer surface of the ‘A’ grains, one at a time. Install the first ‘A’ grain into the liner with a twisting motion, with the uninhibited end toward the forward grain.
   1. 
   2. Apply 30-minute epoxy to the pre-inhibited ends of the ‘A’ grains, one at a time.

   

7. Install the second ‘A’ grain into the liner with a twisting motion ,with the pre-inhibited end facing the pre-inhibited end of the first ‘A’ grain.
8. Install the second grain spacer O-ring into the case after the second ‘A’ grain is installed.
9. Repeat steps 5-8 exactly for the ‘B’ and ‘C’ grain sets, except that no grain spacer O-ring is installed after the second ‘C’ grain.
10. Use the nozzle to push the second ‘C’ grain to the proper depth in the case.
11. Clean the nozzle end of the liner and the nozzle flange with acetone to remove all traces of glue.
12. Apply grease to the nozzle end of the liner and nozzle flange to prevent expanding glue from bonding the nozzle to the liner.
13. Follow the included 98mm RMS instructions to complete motor assembly. Stand the finished motor on the nozzle end and allow to cure for 24 hours before use.
