Assembling the GL Block Assembly
1. Attach the tension coil spring to each gear.
To differentiate the S side and T side, the side with more coils
is the T side. The S side has less coils. Face the ends of the
spring towards you, the tip of the coil (lower side) is positioned
at the right for the S side and at the left for the T side.
2. Hook the spring to the GL arm, and rotate in the ,2 direction
until the claw of the GL arm passes over the part, and the
becomes visible. When the GL arm is completely inserted, the
GL arm claw will pass below the part by the tension of the
spring (,3).
