Preliminary Steps
1.
Verify all the parts listed before installing
the linkage.
2.
Choose an actuator from one of the series
listed below. There is a torque reduction
when using the ZG-JSL linkage. Verify
application requirements before use.
* ZG-121 adapter must be used with EF.
** GM/GK not for use with 1/2" shafts.
*** K6-1 clamp must be used with LF.
3.
Determine proper location to install the
linkage onto the damper’s jackshaft. Verify
that there are no obstructions and that the
damper blades do not collide with the
linkage. If available, refer to the damper
manufacturer’s dimensional drawings; the
dimensions of the shaft bearings and
damper blades are usually published.
