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 on 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 large cylinders. When machining a split Tiller Arm, it is important that shims are placed between the 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 our 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.
