HEAD SECTION REMOVAL PROCEDURE
(Refer to drawing number 1068–232–10 pages 43.2 & 43.3 for part reference)
1. Raise the bed to a comfortable working height.
2. Remove the plastic neck piece cover (item X). Rotate the neck piece so it is parallel to the ground.
3. Using the 1/8” roll pin punch, punch out the 1/8” roll pin (item AX) in the back of the anti–rotation gear
(item K).
4. To loosen the anti–rotation adjustment wedge, use the screwdriver to hold the anti–rotation adjustment
screw (item M) from underneath the neck section and, using the 3/8” wrench or socket, loosen the lock
nut on top (item AK) by turning it counterclockwise. (It is not necessary to remove the lock nut or adjust-
ment screw).
5. Allow the head and neck assembly to drop down for easier access to the jam nuts (item AL) and flange
nuts (item AF) on the neck pivot rod (item T). Loosen the jam nut and the flange nut closest to the left
side (the gear and wedge side) on the pivot rod and spin the nuts as far to the left as possible.
WARNING
Support the head/neck assembly to prevent it from falling and causing damage or injury during the removal
of the neck pivot rod.
6. From the left side, push the neck pivot rod (item T) as far right as possible. A thin nylon washer (item
AT may fall out from between the neck assembly and the Fowler adapter bracket on the right.
7. Spin the jam nut and flange nut that were loosened in step 5 to the left and remove them from the rod.
Remove the second jam nut and flange nut. Being sure to support the head/neck assembly, push
the pivot rod out to the right. Another thin nylon washer may fall out from between the neck assembly
and the Fowler adapter bracket on the right.
