A tool is provided for adjusting the loading of the isolators using the wedgemounts. The tool is a 7/16
(11.1 mm) hex rod 5.75” (146 mm) long. There is an oval hole on the side of the top cover of the isolator
where the tool can be inserted to engage the wedgemount. There are three notches on the rod to
indicate the position (height) of the wedgemount. When the tool is fully inserted into the wedgemount, the
position of the notches relative to the outer surface of the isolator indicates the height as follows:
Figure 9: Wedgemount Access Hole
Figure 10: Load Adjustment Tool
Tool Notch Location Relative to
Isolator Outer Surface
Wedgemount Position
Inner notch is flush
fully down (minimum usable height)
Center notch is flush
mid height position
Outer notch is flush
fully up (maximum usable height)
To adjust the load on the isolators, proceed as follows:
A) Confirm that all of the wedgemounts are at their mid height position.
B) Depending on the displacement reading (refer to the previous section on displaying the reading on
the controller LCD), increase the loading of the isolators by turning the tool clockwise (the
displacement value increases)) or decrease the loading by turning the tool counterclockwise (the
displacement value decreases) until all isolators are loaded within the proper displacement range for
the weight of the supported payload
The following procedure applies only to a 4-isolator system.
When performing the load adjustment procedure, the cable to the HVA connector
(bottom of the Isolator) must be disconnected.
