2. In order to secure the plunger, insert a stopper pin with a diameter of 2.5 mm (0.098 in) or a hex wrench with a diameter of 2.5 mm into the stopper pin hole.
NOTE: If the stopper pin hole on the link plate and the stopper pin hole on the chain tensioner are not aligned, check that the first notch of plunger rack (A) is engaged with the stopper tooth (B). If not engaged, retract the plunger a little so that the first notch of plunger rack (A) is engaged with the stopper tooth (B).
