Installation guide

18 MK II Wheel Drive

Horizontal alignment

When viewed from above (as shown in the illustration above):

• the sensor arm must be between 75 mm (3 in) and 310 mm (12 in) from the tiller arm

• with the rudder amidships, the sensor arm should be at 90° to the connecting rod and

directly opposite the cable entry point on the sensor body

• when the rudder moves from hardover to hardover:

• the sensor arm and the tiller arm must remain parallel to each other at all times

• sensor arm movement must not exceed +/- 60°: if the steering system drives the sen-

sor arm beyond these limits it will damage the rudder position sensor
