Adjust Clevis on Thoracic/Lumbar Push Cylinders
To Resolve: Cushion does not stay up when weight is on the cushion:
Use a small screwdriver to pull the retaining clip off the clevis pin at the location of the arrow. Push the pin out of the clevis.
Select the drop. Step on the pedal to extend the cylinder.
Wrap a rag around the rod to protect it and then clamp pliers to hold the cylinder rod from rotating as the clevis is turned.
Unthread the clevis three full turns and replace the pin. This adds 1/8" to the length. Test the drop.
Return the retaining pin by pushing it into the groove on the pin.
