[3] -4. Replacing Torque Limiter Complete

6) Assemble slider support to gear housing cover complete as illustrated in Fig. 22.

1) After removing insulation cover and shoe, separate gear housing cover complete from gear housing. (Fig. 15)
    It is not necessary to remove lever 20 and pin 7.
2) Remove bearing box from gear housing by unscrewing three M5x16 pan head screws (adhesive-coated),
    then the hexagon hole of torque limiter will be visible. (Fig. 23)
3) Secure crank cam complete in vise, then insert hex wrench into the hexagon hole.  By turning the hex wrench
     counterclockwise, torque limiter can be disconnected from crank base complete of the crank section. (Fig. 24)
    CAUTION:
    Never use impact driver for turning the hexagonal hole of torque limiter or you may alter the factory-adjusted
    torque setting.
4) Separate crank cam complete and crank base complete from torque limiter.
