INTRODUCTION
Capilano
Helms and Cylinders are engineered and manufactured for heavy duty marine
usage, and are suitable for commercial, work boat and pleaseure boat applications.
Capilano Hydraulic Steering has been designed to meet ABS, Lloyds and
DNV specifications.
For
all Pleasure and Work Boat applications 38ft. (11.5m) and smaller with
some exceptions, please refer to our SeaStar
range of Inboard Steering Systems.

SELECTION
GUIDE
This
selection guide is designed to assist in selecting a Capilano
Steering System. Teleflex (Canada) Limited cannot anticipate all the variables
in boat-rudder design that affect steering loads. If the required information
is not available, e-mail the Technical
Service Department with rudder dimensions, vessel size and anticipated
maximum vessel speed.

CYLINDER INSTALLATION
|
|
| |
Features |
-
Regular duty aluminum cylinders.
-
Heavy duty brass cylinders.
-
Easy installation for single and
dual rudder vessels.
-
Cylinders supplied with bleeder
fittings.
-
Two axis articulation.
-
Easy autopilot interface.
|
|
|
|
|
| Proper
cylinder installation is the key to the successful operation of the hydraulic
steering system. An incorrectly installed cylinder is subject to rapid
seal and bearing wear and non-repairable damage.
An
imaginary line drawn through the tiller arm hole at both hard over positions
will create the cylinder centre line. With tiller arm at hard over positions,
angle X and Y should be the same. Select the diagram
and dimensional data that corresponds with your cylinder model.
Not all possible cylinder mounting configurations are shown, however,
all necessary dimensions are shown regardless of mounting configurations.

CAPILANO HELM PUMPS 1250V,
1275V & 1350
A
unique variable displacement feature on the 1250V and 1275V helms allows
the helms-person to adjust the amount of steering wheel turns to their
preference within a predetermined range. The 1350 helm is a fixed displacement
pump.

TUBING, HOSES & FITTING KITS
The use of seamless soft annealed refrigeration copper tubing, type L
is recommended. If flexible hose is required, use hose that has a minimum
operating pressure of 1000PSI, a burst pressure of 5000PSI and the lowest
available expansion factor. The 1250V requires the use of 1/2" OD
copper tube while the 1275V requires the use of 5/8" OD copper tube.
The 1350 Helm Pump requires the use of 3/4" OD copper tube.
|
Cylinder
Hoses
|
|
Steering systems installed with copper
tubing require short pieces of flexible hose to accommodate slight
cylinder movement. Hoses are supplied with 1/2" swivel flare nuts
on each end. Hoses are sold as a pair for single cylinder applications
and separately for the variables of twin cylinder installations.
| The
following hoses are for single cylinder applications. |
