The Cylinder Alignment Valve (part # HA5471-2) will allow for the periodic required
realignment of two outboard motors or rudders that are linked together with a
Hydraulic Tie Bar as opposed to a solid link or a Mechanical Tie Bar.
Boats exceeding 55 mph must use the SeaStar Pro Helm Pump (part# HH5770)
and SeaStar Pro Kevlar Hoses.
Due to the potential for leakage across the piston seals, it is possible for the
engines to get out of synchronization. We are unable to predict, due to
circumstances beyond our control, the frequency that misalignment may occur,
therefore Engine alignment should be checked and corrected as required before
leaving the dock.
Referencing the cylinder alignment
valve installation schematic.
• Fill helm with oil and attach filler
device / container to helm
• Open valve
• Open bleed fitting no. 1 and pull
cylinder shaft all the way out on
fitting no. 1 side of cylinder
• Turn steering wheel clockwise until
an air free stream of oil comes
for th from bleed fitting no. 1
• Close bleed fitting no. 1
Cylinder Alignment Valve
Bleeding Instructions
• Open bleed fitting no. 2 and pull
cylinder shaft all the way out on
fitting no. 2 side of cylinder
• Turn steering wheel
counter-clockwise until an air free
stream of oil comes for th from
bleed fitting no. 2, then close
bleed fitting no. 2
• Open bleed fitting no. 3 and pull
cylinder shaft all the way out on
fitting no. 3 side of cylinder
• Turn steering wheel
counter-clockwise until an air free
stream of oil comes for th from
bleed fitting no. 3, then close
bleed fitting no. 3
• Open bleed fitting no. 4 and pull
cylinder shaft all the way out on
fitting no. 4 side of cylinder
• Turn steering wheel
counter-clockwise until an air free
stream of oil comes for th from
bleed fitting no. 4, then close
bleed fitting no. 4
• Turn steering wheel back and for th
from hardover to hardover a couple
of times. Align cylinders by pulling
cylinder rod all the way out on the
same side of each cylinder and
close valve
WARNING
CAUTION
DO NOT allow cylinder body to move
(HC5345), or shaft to move back
into cylinder (HC5370).
DO NOT use a wrench to hold cylinder.
CAUTION
Side Mount or Unbalanced Cylinders,
such as SeaStar cylinder HC5370
can only be used with the valve by
re-orienting the port engine tilt tube,
to allow for mounting cylinder on the
port (left) side of the port engine.
Cylinder rods must face each other.
The use of a standard helm at high
speed (55 mph +) or a high load,
eg: full throttle forward/reverse,
may cause a vacuum in the liquid
tie bar and cause engine/rudders to
misalign, resulting in momentary
loss of steering control. This will not
occur if a SeaStar Pro Helm Pump
(part # HH5770) is used.
If a mechanical tiebar can be used, it is advisable that one is fitted. There is no
substitute for a mechanical tiebar
