To Install The FB40-29T Teflon Packing

The teflon (#6) ring must be thoroughly moistened before tightening up the housing, either by soaking the teflon ring in a cup of water (soak for about 45 minutes) before assembling.

OR

Install the packing parts as above, but DO NOT tighten the nut and let it run for about 45 minutes before tightening the force head nut. ALWAYS TIGHTEN UP THE FORCE HEAD NUT BY HAND – NEVER WITH A MONKEY WRENCH. If the nut is over tightened the force head rod will wear. Give the packing a few drops of oil every two weeks or so.
