Selection Guide
Helm Options
Four helms are offered in 3 displacements, as noted in the chart at right.
The H-21 helm has a 1" straight wheel shaft; H-25 has a 3/4" tapered
shaft. The H-42 and H-41 helms both have a 1" straight wheel shaft.
Tubing/Hose Options
Use soft refrigeration type copper tubing for optimum performance. For
tube-to-cylinder flex hoses, select a hydraulic hose rated for 1000 PSI (70
bar) working pressure, and with a very low volumetric expansion rating.
Cylinder Options
Cylinders are made from brass & stainless steel. Available with stainless rod
& ball joint (TMB models) or stainless rod & bronze clevis (TMC models.)
Cylinders with ball joints have 2-axis articulation.
The K-31 is an optional pivot mount cylinder which can be used in the systems
numbered "8a" and "8b" on the opposite page. With this cylinder, the number
of wheel turns becomes 6.4 (using the H-42 helm) or 4.6 (H-41 helm).
The application guide on page 6-3 should be used with discretion. The
chart is only a guide to selecting a steering system. A steering system
manufacturer cannot anticipate all the variables in boat-rudder design
that affect the steering loads. It is the final responsibility of the boat
builder/designer to specify maximum expected steering loads. If the
required information is not available, please see the Displacement and
Planning Hull data sheets on page 10-21 and page 10-22. These
sheets after being completely filled out can be faxed to Teleflex
Technical Support at 604-279-2202.
