You will install guide bars and drive
shafts that match the lens of your

guide bars, drive shafts and port
rings to use for your lens is

Secure Guide Bars. Insert the guide bars by threading them into the front
bulkhead. Tighten firmly by hand
– no tools are required but wrench flats are
provided on the guide bars should this be necessary.

Install Drive Shafts. These
are ¼” black delrin and have a flat spot milled into
one end. This end inserts into the drive coupler at the face of the front bulkhead.
Secure gently with the set screw on the coupler. Do not overtighten.

LGD’s mounting. Install the LGD’s in their proper orientation with pivot gear
screws facing forward. Slide it onto the guide bar and drive shaft, then line up
the LGD with the lens gear you wish it to access.

LGD’s – 2x CCW and 1x CW.
Insert the drive shaft into the
