3. Remove the four bolts, nuts and washers holding the Front Wire Guard and remove the wire guard. Retain

these parts for re-installation later. See Figure 1.

4. Locate the Damper Ring Assembly (52"/6403-3151, 36"/6403-3165,48”/6403-2705), the Top Ring Bracket

(52"/0404-8016, 36"/0404-10185, 48”/0404-10814), the two Side Ring Brackets (52"/0404-8017, 36"/0404-
