TORSIONAL DAMPER
N O T I C E :
The inertia weight section of the
torsional damper is assembled to the hub with a
rubber sleeve. The removal and installation
procedures (with proper tools) must be followed or
movement of the inertia weight section on the hub
will destroy the tuning of the torsional damper,
and the engine timing reference.
The torsional damper has (3) timing notches on
the inertia ring. The # 1 cylinder timing reference
mark will be identified by a dab of white paint in
production. If a new damper assembly is installed,
mark the new assembly in the same location for future
reference. # 1 cylinder reference is the first mark
clockwise from the keyway when viewing the engine
from the front.
