Caution:
It is important to note that the hydraulic linear actuator can exert a
thrust of upto 2700 Ibs - this is the equivalent weight of a large
family saloon car. If there is any doubt about the strength of the
existing tiller arm or quadrant the steering gear manufacturer
must be consulted. Also, the mounting foot should be bolted to a
substantial member and always over engineer to ensure reliability
and maintenance of correct alignment.
