(1) To remove lumbar cushion assembly (Refer to Figure 6002)
The lumbar cushion assembly, P/N 48210213 (Longhaul), consists of fabric support (non-procurable part), lumbar bladder, and valve actuator assembly.
(a)
Remove the fabric support (1) from lumbar bladder (2) by unfastening hook-and-pile.
(b)
Remove the valve actuator assembly (3) from bladder by pulling out the valve actuator to overcome the friction seal of the lumbar bladder.
NOTE: Older style lumbar valve assemblies (as pictured) are no longer available from the manufacturer. New replacement valve assemblies are modular and do not disassemble.
(2) To install lumbar cushion assembly (Refer to Figure 6002)
(a)
Install valve actuator assembly (3) into lumbar bladder (2) by pushing the valve actuator assembly into the bladder actuator opening located on the side of the bladder. Apply sufficient pushing force so as to allow a friction seal to occur.
NOTE: Failure to properly install the valve actuator assembly (3) into the bladder may cause the lumbar cushion assembly not to operate properly.
(b)
Restore to operation and test function.
D. Remove and Install Recline Control Hydrolok and Adjust Back Recline
