Servicing the Valve Assembly
Should the valve fail, remove it for servicing. A replacement Paddlewheel & Valve Kit
33-415 is available.
1.
Remove the short emergency plug from the safety wire (see Figure 2).
Warning: The O-ring must be intact and well lubricated to make a watertight seal.
2.
'Inspect (replace if necessary) and lubricate the O-ring with silicone lubricant or
petroleum jelly (Vaseline ® ).
WARNING: When the valve assembly is removed, always insert the short
emergency plug with the cap nut and safety wire for a watertight seal.
Unscrew the cap nut. With the short emergency plug ready in one hand, remove
3.
the paddlewheel insert and valve assembly as one unit by pulling upward on the
pull ring. Rapidly insert the short emergency plug to minimize the flow of water
into the boat.
Note: The plug is not secure until the cap nut is in place.
To free the cap nut, remove the paddlewheel insert from the valve assembly by
4.
removing one safety ring and the retaining pin. Grasp the insert by the pull ring
and pull slowly upward.
WARNING: If the insert is caught in the valve assembly trapping the cap nut,
TEMPORARILY hold the short emergency plug in place with the safety wire.
Then, separate the insert from the valve assembly. If they cannot be separated
and the sensor must be left unattended, cut the cable [a minimum of 1m (3') from
the insert] to free the cap nut.
Warning: Always use the cap nut and safety wire to secure the short emergency
plug for a watertight seal.
5.
Secure the short emergency plug with the cap nut. Hand-tighten only. Do not
overtighten. Re-attach the safety wire.
6.
Separate the valve assembly from the paddlewheel insert.
7.
Clean, repair, or replace the valve assembly, so the flap valve moves freely and
seats against the valve housing (see Figure 5).
Warning: The O-rings must be intact and well lubricated to make a watertight seal.
