5. Loosen and remove the whisker retaining screws,
remove the retaining plates then pull the regulator
and whisker free. Use caution not to lose the whisker
spacers. The rubber whisker is removed by stretch-

regulator "whisker flange". The "whisker flange"
forms the exhaust valve seat and surrounds the regu-

whisker flange., To remove it, pull the whisker free.
6. Clean the valve and valve land area of the regula-
tor body.
Note: Whenever the whisker is removed or replaced,
the exhaust valve should be carefully cleaned and
inspected. Replace the valve if any damage or de-

replaced during scheduled overhauls or at least
once a year.
Note: Before removing the regulator exhaust valve,
carefully inspect the area around the edges to as-
sure the silicone exhaust valve is in contact with
the regulator body. Ensure the spokes that hold
the exhaust valve are smooth, even and not bent.
The exhaust valve seating area should be free of

and seal properly. The metal cross-area of the body
under the valve could be slightly bent out resulting
in the rubber valve not sealing.
