19 Backrest Damper - Replacement
This section describes how to replace the backrest damper. Reference is made throughout this section
to Figure 3 on page 29.
19.1 Removal
To remove the backrest damper:
19.1.1 Raise the backrest to maximum height. If the backrest actuator (Fig 3, Item 7) has been
removed, use the hoist to support the backrest in position.
19.1.2 Pry off and discard both starlocks (Fig 3, Item 10) and remove the backrest damper
(Fig 3, Item 2).
19.2 Installation
To install the backrest damper:
19.2.1 Assemble the new backrest damper (Fig 3, Item 2) onto the brackets on the backrest
(Fig 3, Item 1) and sub-frame assembly (Fig 3, Item 11), adjusting the angle of the backrest as
necessary. Note that the damper piston (ram) must point towards the head end of the bed.
19.2.2 Secure the damper with two new starlocks (Fig 3, Item 10); make sure the damper is free to
pivot on the brackets but is not too loose.
