Clean the damper with a solvent cleaner.
The viscous damper is filled with a silicone fluid. After
many hours or use, the silicone fluid may become
thicker and expand. To determine if the damper
thickness is correct, remove the paint from the damper
in four locations on either side of the damper. Measure
and record the thickness of the damper in four places.
Measure the thickness 3.175mm [0.125 inch] from the
out side of the damper. Replace the damper if its
thickness varies by more than 0.25 mm [0.010 inch].
Spray the damper with spot check developer, Type
SKD-NF or its equivalent. Heat the damper in an oven
(rolled lip side down) at 93C [200F] for 2 hours.
WARNING
Wear protective gloves to prevent personal
injury when handling parts that have been
heated.
Remove the damper from the oven and check for fluid
leakage. If there is leakage, replace the damper.
