Figure 8.1  Good force measurement practice

Center the load

on the shackle pin.

Use spacers to

insure centering

where applicable.

Use only with

a pin of the 

same diameter

and hardness

as the original 

factory equipment.

Do not torque, 

bend or 

sideload.

Use hardware that allows

single point attachment 

and freedom of alignment.

Do not use hardware that 

is undersize or restricts

self-alignment. This results in

poor measurement 

performance and possible 

dangerous safety conditions.

Be sure fixturing does 

not bind between the 

body of the EDjr and 

the shackle!
