DISASSEMBLY: To remove impeller, apply localized heat to the impeller hub to a
temperature between 150oC - 250oC. Heat Impeller hub for 1-3 minutes. This will
decrease the breakloose strength of the Loctite 271 and allow for easy removal.
ASSEMBLY: To install impeller clean shaft thoroughly with denatured alcohol let dry.
Apply Loctite 7649 primer to shaft, impeller threads and allow 3-5 minutes to dry.
Apply 3 drops of Loctite 271 high strength threadlocker to shaft threads and 2 drops to
the impeller threads. Tighten impeller and jam nut to 144 lb-in or 12 lb-ft. Allow
impeller to cure for 30 minutes before testing or running.
