To remove the exhaust body you must remove the
three screws inside the helmet shell.
7.10 Water Dump Exhaust Body
The water dump exhaust assembly is mounted onto
the bottom of the helmet by three screws that are
installed on the inside of the helmet shell. RTV sili-
cone sealant is used to seal the water dump body to
the helmet shell.
7.10.1 Water Dump Valve Removal
Tools Required:
Flat Blade Screwdriver
1) The Quad Valve cover can be removed by unscrew-
ing the two screws. If the cover is badly dented so
that it interferes with the performance of the exhaust
valve it should be replaced.
2) The rubber exhaust valve should be replaced at the
slightest sign of deterioration or aging of the rubber.
Simply grasp the valve and pull to remove.
7.10.3 Water Dump Valve Body Removal
1) The water dump body should never need servicing.
If it is to be removed, you must first remove the three
screws inside the helmet shell.
After this is done, gently twist the valve body off of
the helmet shell. A putty knife may be used to slide
between the valve body and the shell to break the
RTV sealant.
7.10.4 Water Dump Valve Body Remounting
1) To replace the main exhaust body, first be sure to
clean the helmet and the main exhaust body of the
old silicone sealant prior to remounting.
Place a coating of RTV silicone sealant on the
mounting surfaces and around the mounting holes,
and mate the body to the helmet and start to tighten
the mount screws on the interior of the helmet. Wipe
off the excess RTV silicone sealant that is squeezed
out. Tighten the screws to 12 inch pounds.
7.10.2 Water Dump Valve Replacement
1) The rubber exhaust valve is installed by inserting
the center stem through the exhaust body then pull-
ing from the inside of the helmet shell until it snaps
into place.
2) When installing the quad exhaust cover be sure
to never use longer screws that would protrude into
the interior of the exhaust body as this would interfere
with the operation of the rubber exhaust valve .
also cause long term damage to body tis-
sue. Read and follow all precautions listed
on the silicone sealant tube and Material
Safety Data Sheet.
