Cleaning and Inspection (1-23)
Clean the damper with hot soapy water and a brush. After
rinsing with clean water, use compressed air to dry.
Check the index lines (A) on the damper hub (B) and
inertia member (C). If the lines are more than 1.59 mm
[1/16 in] out of alignment, replace the damper.
Inspect the rubber member for deterioration and missing
pieces. If pieces of rubber are missing or the member is
more than 3.18 mm [1/8 in] below the metal surface,
replace the damper.
NOTE: Also look for forward movement of the damper ring
on the hub. Replace the damper if any movement has
occured.
