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.


1250V & 1275V Helm Pumps

1350 Helm 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.
