• It is important that the 7148 and 7158
are installed so that the mechanical
feedback linkage between the rudder
stock and the Power Follow-Up unit will
be square in mid-position, and that the
strokes will allow the rudder to go hardover
to hardover using all of the available
stroke from the Power Follow-Up unit.
• The foundation plate must be flat,
vibration free and securely attached to
the ship’s hull. The oil supply pressure
enters port “P”. The fitting provided at
port “P” should not be removed or turned.
The Helm Pump lines are connected
on the underside of the units. The two
outgoing lines “A” and “B” to the main
steering cylinder must be connected in
accordance with the drawings provided.
If these lines are incorrectly connected,
the Power Follow-Up will shift the rudder
hardover to one side and it will remain
there. Crossing the lines to the main
cylinder will cure this problem.
• Any lost motion in either the main
steering system (Tiller Arm, Rod Ends,
loose Rudder Stock etc.) or in the feedback
linkage will cause the steering system
to be inaccurate and to “hunt”. It is
extremely important that all connection
points are tight without lost motion.
• For specifics, please contact Kobelt
Manufacturing.
