5.6 Power Steering System Diagram
The power assist unit provides automobile like steering on your catamaran. The unit is installed in the
console between the helm and steering rams. The power for the unit is connected to the port and starboard
key switch. If you choose to troll with only one engine your power assist will still be operational.
NOTICE
If possible, have your dealer or trained marine technician perform routine maintenance or repairs on
your steering system. Replace faulty parts immediately.
5.6.1 Power Steering System - Bleeding Instructions
Reference the bleeding instructions provided by the SeaStar Solutions
®
owner’s manual, which is included
in your Owner’s Portfolio. Use them in conjunction with the instructions and diagram below to bleed the
steering system. This should be done annually or when air is detected in the system.
Step 1
•
With the Power Purge turned "OFF", attach helm fitting and leads.
•
Attach one of the leads to the bleeder valve on the Power Assist Pump.
•
Open the bleeder valve using a 5/8" wrench.
•
Turn the Power Purge unit "ON".
•
Watch for air bubbles in the clear hydraulic lines. Once no more bubbles can
be
seen and there is a steady flow of hydraulic fluid through the lines, allow
the Power Purge to run for an additional 60 seconds.
•
The helm is now full of fluid. Turn Power Purge "OFF". Close bleeder valve and
disconnect line from the Power Assist Pump. Place dust cap back on bleeder
valve.
Step 2
•
Attach the four lines to each of the bleeder valves on the
steering cylinders.
•
Open each of the four bleeder valves.
•
Turn Power Purge "ON".
•
Turn the steering wheel slowly 20 times clockwise, then
slowly 20 times counter-clockwise.
Step 3
•
With Power Purge turned "ON", move both engines through their
full range of motion
(This will help remove any air bubbles still trapped inside the
cylinders).
•
As a final precautionary step, pull on the engines firmly at the ends
of their normal range of motion
(This will also help to insure all of
the air is out of the cylinders).
Step 4
•
Turn the ignition key for the port engine "ON". This will turn
the Power Assist Pump "ON”.
•
Repeat "Step 2".
•
If no more bubbles can be seen then the bleeding is complete. Turn
the
Power Purge 'OFF". Close all four bleeder valves. Disconnect the
four lines
from the cylinders and both lines from the helm. Remove
the helm fitting
and replace it with vent cap.
•
If bubbles are still present in lines, then bleeding was
not successful. Repeat entire process.
