(inside diameter).

: Use a suitable punch to drive the
anchor pin (1) out of the
crankcase in the direction of the
arrow.
Do not drive out the pin in the other
direction as this would damage the
annular bead which was formed in
the crankcase bore when the pin
was originally installed. In such a
4 case neither the new anchor pin nor
the brake spring would locate
2
properly. Furthermore, the
crankcase could be damaged in this
way and possibly impair correct
operation of the chain brake.
