Camshaft Removal; Automatic Compression Release Inspection - Polaris Outlaw 500 Service Manual

4. To retract the plunger, rotate the special tool clockwise
while holding the tensioner stationary. You may also hold
the special tool stationary and rotate the tensioner assembly
counterclockwise if desired.
IMPORTANT: Do not grind edges of key flange into
tensioner to prevent damage to the tool or locking
guides during plunger retraction.
5. Once retraction is complete, lock the tool into the 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 (Page 3.3). Remove the special tool and
replace the tensioner cap.
