The Tiller Arm serves a very important function. It converts
the linear motion on a steering cylinder into the rotary
motion of the rudder stock.
It is, therefore, very important that the Tiller Arm is
of sufficient strength to withstand all the pounding,
mechanical and hydraulic force imposed upon it under
severe conditions.
Stock Tiller Arms are available from Kobelt in many shapes
and sizes. We also manufacture custom made Tiller Arms,
especially for bigger applications, where we are working to
specific rudder stock dimensions and larger cylinders.
When machining a Split Tiller Arm, it is important that
shims are placed between the two halves. This will allow the
clamping pressures to be applied to the rudder stock. The
keyways must also be machined on size and parallel to the
shaft. No lost motion should exist between the Tiller Arm
and the rudder stock.
This is especially important when a Full Power Follow-Up
Hydraulic system is installed such as the Model 7148. It is
recommended to periodically check all bolts pertaining to the
Tiller Arm and Steering Cylinder to ensure that they are tight
and that all components are in good working order.
Custom hole sizes are available.
