Assembling the chassis assembly (2-1)

3-1

Installing the lens barrel assembly (7-23) on the chassis

Insert the interlock rod assembly (7-121) into the hole on the positioning plate

assembly (7-113), apply grease (FHA-054) to the Bteel ball (7-122) slightly, fit the lens

barrel assembly (7-23) to the chassis, and secure it tightly with four screws (1-7).

(Rated tightening torque: 4r6kg-cm)

Checking the flange for flatness

Remove the front lens assembly (7-4), screw a jig into the lens threads taking place of

the front lens assembly, turn the chassis up side down, and measure four comers of the

rail plane with a dial gauge to insure that the difference among four measured values is

within 0.06mm.

When the difference exceeds 0.05mm, apply a washer or tin foil to the lens barrel

installing plane to adjust the difference so that it is within 0.06mm.

Out of four positions, one position must not use washer or tin foil (highest position).

NOTE:

To check flange plane, an optical type parallelism checker may be used.
