A. Remove the crankshaft damper bolt. (A fac-

tory tool may be used to keep the engine

from rotating or carefully use a pry tool to

keep the damper from rotating.)

B. Install the supplied drill guide with the raised

section piloting in the damper bore. 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). See

Fig. 2-a.

C. Using a small drill motor (right angle pneu-

matic works well), mark a 1/4” drill bit with

electrical tape or a drill stop so that the hole

will be deep enough for the supplied 1/2” long

dowel pin. See Fig. 2-b.

D. Drill hole in damper/crankshaft.

E. Remove the socket head cap screw.

F. Clean area of metal chips and install the sup-

plied dowel pin in the drilled hole making sure

that it does not protrude past the damper

face.

G. Install and tighten the crankshaft damper bolt

to 129 ft-lbs (176 Nm).

1” MINIMUM

NOTE: The purpose of this section is to provide access to the har-

monic damper bolt area so that the crankshaft can be pinned

to the damper to prevent the damper from spinning on the

crankshaft. The following steps will work on all or most appli-

cations. If it is not possible to get adequate clearance by per-

forming the following steps, follow the manufacturer’s steps

for removing the harmonic damper until there is sufficient

room to work in.
