: Drive the pin (1) out of the
crankcase with a drift in the
direction indicated.
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
case neither the new anchor pin nor
the brake spring would locate
properly. Furthermore, the
crankcase could be damaged in this
way and possibly impair correct
operation of the chain brake.
– Before installing the new pin,
coat its knurled shank with
Loctite – b 16.
– Position the new pin in the bore
so that the knurling on the pin
meshes with the existing knurling
in the bore. Turn pin back and
forth as necessary.
: Carefully tap home the pin
squarely to obtain dimension "a"
(about 4.3–4.7 mm)
(0.17–0.19 in).
The pin must be driven home
absolutely square.
