1.

  At ALL times protect cylinder shafts from nicks and scratches. A 

damaged cylinder shaft cannot be repaired and MUST be replaced.

2.

  To achieve MAXIMUM performance, cylinder is to be mounted at 

a right angle (90°) to the rudder arm when in the center position 
(refer to Figure A below).

3.

  Ball joint connections allow for no-load pivoting and minor 

misalignment. Ball joint connections are NOT designed to handle 
steering loads when significantly misaligned.

4.

  Mounting area MUST be able to withstand significant forces in 

excess of 

2000 lb

. There must be NO binding or interference of 

the ball joints at any point in the steering arc.
