Replacing Pins

Removing

If the groove of the anchor pin is
worn, install a new pin.
Drive out the pin in the direction of
the arrow so as not to damage the
annular bead which was formed in
the engine housing bore when the
pin was originally installed. The new
anchor pin will not otherwise fit
properly and the brake spring will
not be held securely.
