13.6 Regrease the head spindle
Over time the turn knob may become harder to turn, which may be remedied by regreasing the threaded
part of the turn knob. Perform the following steps to take the valve head apart after having separated it
from the valve body as explained in chapter 13.3:
• Set the valve head in CLOSED position
• Pull off the membrane
• Remove the bushing
• Fix the lower stem in a vice using soft jaws
• Unscrew the valve head top using the tommy bar (hold it back when it gets loose, as the spring
will push it out)
• Pull by the knob to separate it from the union nut
• Unscrew the upper stem from the turn knob
• Lubricate the upper stem’s threaded part in contact with the turn knob
Assembly is the same in reverse order, but please note:
• Discard the membrane and replace with a new one
• Push the membrane and the bushing together so that the membrane is situated against the
shoulder of the bushing
