Robert,

I believe that the information which you are seeking may be found on Chapter 2: Mounting the drive of the Mechanical Linear Drive Installation Instructions. The mid-stroke length may be established with the heim joint rotated fully in and then adjusted to an appropriate orientation to prevent binding when be mated to the tiller pin. After this orientation adjustment has been made, then heim joint's nut may be tightened against to shaft to maintain the desired orientation of the heim joint with respect to the tiller pin. As indicated within the mounting instructions, the linear drive must be installed in a manner such that when it is in the mid-stroke position (consult the manual for the specified mid-stroke length), the rudder is centered.
