clockwise while holding the tensioner stationary.
You may also hold the special tool stationary and
rotate the tensioner assembly counter--clockwise
if desired. IMPORTANT : Do not grind edges of
key flange into tensioner to prevent damage to the
tool or locking guides during plunger retraction.

tensioner guides. This holds the spring and
plunger in place for reassembly. Use caution not
to disturb the tool during tensioner installation.
6. Reinstall the tensioner assembly, torquing the
bolts to specification (Pg 3.2). Remove the
special tool and replace the tensioner cap.
