ings (item 14) in side plates for wear or damage. Re-
move bushings and replace if necessary.
Bedbar Installation (Fig. 19)
1. If rubber bushing was removed from either cutting
unit side plate, install a new bushing. The bushing
should be installed flush with the inside of the side plate
(Fig. 20).
2. If removed, install the flange bushings (item 15) with
flange facingoutward. Applyantiseize lubricantto inside
of flange bushing.
3. Apply antiseize lubricant to the bedbar threads and
the shoulder area of each bedbar pivot bolt.
4. Slide one metal washer (item 17) and one plastic
washer (item 16) onto each bedbar pivot bolt.
CAUTION
Contact with the reel, bedknife or other cutting
unit parts can result in personal injury. Use
heavy gloves when handling the bedbar.
5. Position bedbar into cutting unit. Make sure that the
top of each bedbar arm is between washer (item 11) and
adjuster screw flange (item 10).
6. Position a plastic washer between bedbar and each
cutting unit side plate (Fig. 20).
7. Install the bedbar pivot bolt assemblies. Make sure
that plastic washers are not caught on the threads of the
pivot bolts. Tighten each bedbar pivot bolt from 27 to 33
ft--lb (37 to 44 N--m).

washer just stops rotating. Do not over tighten the lock
nuts as this can distort the side plates and affect reel
bearing adjustment. The plastic washer between the
bedbar and side plate should be loose.

er assembly until the adjuster spring is fully com-
pressed, then loosen lock nut 1/2 turn.
