DISASSEMBLY: To remove impeller, apply localized heat to the impeller hub to a tem­perature between 150oC - 250oC if needed. Heat Impeller hub for 1-3 minutes. This
will decrease the breakloose strength of the Loctite 243 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 243 medium strength threadlocker to shaft threads and 2 drops
to the impeller threads. Tighten impeller to 144 lb-in or 12 lb-ft. No Jam nut needed.
Allow impeller to cure for 30 minutes before testing or running.
