CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result. Do not compress the ratchet

3. While holding the ratchet mechanism, push the ratchet arm back into the tensioner housing.
4. Install a paper clip into the hole in the tensioner housing to hold the ratchet assembly and plunger in during installation.
