DRILL BIT MARKED
AT 3.85" FROM TIP
D. After the new damper is fully seated, remove
the installation tool.
E. Install the supplied drill guide with the raised
section piloting in the damper bore.
Temporarily secure in place by installing the
supplied socket head cap screw. Do not
over-tighten the screw as it may distort the
drill guide (its purpose is just to hold the guide
in place while drilling).
F. Mark the supplied ¼” drill bit with tape or use
a drill stop at a point 3.85” from the tip as
shown in Fig. 2J.
G. Using an angle drill or small drill motor, drill
into the crankshaft/damper hub assembly
through the bushing in the drill guide, taking
care to keep the tool perpendicular to the
damper. Stop when the mark on the drill bit is
even with the face of the damper – this will
yield a hole depth of ½”. See Figures 2I &
2J.
