Timing Chain Assembly: Installation

1. Insert the screw, spring pin and tension rod into tensioner body.
2. While depressing the tensioner onto rubber mat, twist it to shorten tension rod. Then insert the thin pin into the hole between tension rod and tension body to keep it.
   NOTE: Work on the rubber mat or other anti-skid materials.
