318 Load Unit
This section describes how to align a force transducer with the load unit actuator.
The load units shown may vary from what you may have.
The 318.10 and some 318.25 Load Units come with two types of transducer
mounting hardware. One preloads the force transducer with a hex nut; the other
uses a preloader collar with jackbolts or captive set screws.
The 318.50 and some 318.25 Load Units use a preloader collar with six or eight
internal jackbolts to preload the force transducer.
