1. After removing the cylinder head assembly (retainer jig
and chuck assembly jig attached) from under the
press, remove the retainer from the cylinder head and,
grasping both sides of the cylinder head, move it to
another place.
2. Remove the chuck assembly with bushing attached
and move to the work bench.
1. Place the chuck assembly with bushing (jig) on the
work bench horizontally and insert the Allen wrench
into the chuck assembly adjuster head section. At the
same time insert a lever into the round hole of the
chuck assembly rear section.
2. Use the lever and Allen wrench so they are pushed
down front and back and loosen the adjuster.
3. Place the chuck assembly vertically and turn the
adjuster with your finger until the wedge rises about 5
mm.
4. After confirming that the bushing is not touching the
chuck blade section, gently remove the bushing from
the chuck assembly.
Keep the work bench clean so that no dust or foreign
matter adheres to or damages the bottom surface of the
chuck or the outer periphery. Also be sure that the work
bench is level.
