Rudder Angle Sensor Installation - Yamaha Enduro 8 Manual

Rudder Angle Sensor
Installation
Standard version for mounting on
the cylinder piston rod
The rudder angle
sensor must pick up
the rudder move-
ment without any
play.
ATTENTION: The hook length must be
adjusted so as not to interfere with the cylin-
der, when the piston is fully retracted!
To adjust the hook length, proceed as fol-
lows:
1. Remove the lid on top of the Sensor
2. Unscrew the hook
3. Adjust the hook length and tighten the
hook screws
4. Close the lid
The hook must be bent so as to guarantee
a firm grip of the piston rod, even when it is
moving vertically! There must be absolutely
no play.
WARNING: make sure the hook does not
interfere with the rudder arm at full rudder
deflection!!!
The sensor is supplied with a hook. The
hook is properly bent for a piston rod of 16
mm (5/8") diameter.
A hole (6,5 mm / 2/8" diameter and 10 mm
/ 3/8" deep) should be drilled along the axis of
the bolt. A second hole with a 3 mm (1/8")
thread is required to fix the shaft of the poten-
tiometer in the bolt. For different conditions,
the wire hook may be bent as required.
If the linear drive unit has been supplied by
TECNAUTIC, the bolt with properly drilled
holes is provided by the factory.
