GAS SUPPORT ASSEMBLY
The gas support assemblies used to assist opening
are attached to the lid and the body and are secured by
retaining bolts. The supports are color coded (lettering
on each support) for each option group. The original
gas supports have a specified output level and MUST
be replaced with a gas support with the same color
coded lettering
Removal and Installation
CAUTION:
Do not attempt Po remove
or loosen gas support assembly
attachments with lid in any position
other than fully open as personal
injury may result.
1. Prop lid in full-open position.
2. Remove
electrical connector (if present). While
helper supports lid, disengage gas supports from
lift window assembly (view a and b, Fig. 4).
3. Remove bolt covers, retaining bolts and
disengage gas supports.
4. To install, reverse removal procedure.
When reinstalling gas supports, torque the
support-to-body bolts 20 to 28
N-m (15 to 21
ft-lb). The support-to-lift window bolts should be
torqued 5 to
7 N-m (40 to 60 in-lb).
Testing Procedure
If the compartment lift window will not stay in
the full-open position or does not raise, follow the listed
steps to check if the gas
support(s) is worn.
In extremely cold temperatures, below
-29"C,
-20"F, it is normal for the gas pressure to be reduced
and this results in a decrease in the hold-open force
until warmer weather.
