(2) Remove the thrust holding screw  C   (for easier removing wipe off the thread lock).
(3) Remove the two motor fitting screws M1.4  D  , and replace the motor  E  . Motor is replaced in the state while the worm  F  is

kept press-fitted to the output shaft.

Note: When installing the motor, take care so that the worm does not damage the ANG  B  hole.
(4) Screw in the thrust holding screw  C  , adjust the worm front end clearance to 0 to 0.1 mm, and apply screw lock.

6. Disassembling the mechanism chassis from the moving chassis

(1) Remove the insulator  B  (2 pcs. at the right side in diagram) parallel in the arrow direction.

(At this time it is better to insert the fine head of screw driver at the ID side of insulator and to move in the arrow direction, which
facilitates removal.)

(2) Remove the mechanism chassis in the arrow direction, pulling upward aslant.

At this time take care so that the insulator  C  (left side, 2 pcs.) is not damaged. (Do not put at once the mechanism chassis
assembly.)
