Install a wave washer onto the adjuster shaft and slide
the adjuster shaft into the flange bushings in the cutting
unit frame (Figure 33).

Secure the bedbar to each side plate with the bedbar
bolts (nuts on bolts) and 6 washers. A nylon washer is
to be positioned on each side of side plate boss. Place a
steel washer outside each of the nylon washers (Figure
33). Torque bedbar bolts to 27-36 N-m (240–320
in-lb). Tighten locknuts until the outside steel washer
stops rotating and end play is removed but do not
overtighten or deflect side plates. Washers on inside
may have a gap (Figure 31).

Tighten the nut on each bedbar adjuster assembly
until the compression spring is fully compressed, then
