Mounting
When siting the linear drive unit, the following points should be noted:
• The drive unit mounting bracket can be attached to any horizontal or
vertical surface. Also, the drive unit can be mounted upside down if
required.
• The ball end fitting will allow up to 5 degrees misalignment between the
pushrod and tiller arm plane of rotation. Accurate angular alignment is
extremely important and, therefore, under no circumstances should this
limit be exceeded.
• The drive unit must be at right angles to the tiller arm when the rudder is
amidships.
• The drive is clear of any bilge water.

• The mounting bracket should be bolted to a substantial frame member.
Always over-engineer to ensure reliability and maintenance of
correct alignment.
The pushrod ball end must be attached to the tiller arm, using the adaptor
pin (supplied), with its flange positioned between the ball end and the tiller
arm. It is vitally important that the lock washer (supplied) is used and that
the nut is tightened fully.
The mounting bracket should be attached with four stainless steel 3/8in.
bolts and locknuts/lock washers.
Having installed the drive unit, turn the steering wheel from hardover to
hardover and check that:
• no part of the drive unit fouls the vessels structure.
• the mechanical limit stop on the vessels steering system is reached
before the actuator reaches its mechanical limit.
• angular movement of the ball end fitting is less that 5 degrees.
