Since repeated bendinglstraightening
damages the tongue, replace the lock plate
w i t h a new one whenever the lock plate is
removed.
Align the tongue t o the nut in such a manner
that the nut aligns perfectly when proper nut
torque is reached, or so that the nut must be
tightened further t o align the tongue.
Do not align the nut in a position where the
locking tongue aligns, but the nut torque is
less than specified.

RIGHT WRONG
Since repeated bendinglstraightening
damages cotter pins, always use new cotter
pins during assembly.
T i g h t e n the nut to the specified torque. Then
align the next possible pin hole while tighten
ing the nut just beyond the specified torque.
-
Do not align the holes i n a position where
the nut torque is less than the specified
torque.
Bend the cotter pin as shown below.
RIGHT WRONG
.
Since repeated bending /straightening
damages cotter pins, always use new cotter
pins during assembly. Although slip pins can
be used again, replace slip pins with new
ones if they are deformed or fatigued.
When using a cotter pin or slip pin on
suspension and wheel components, install
the pin with the head facing forward. If in-
stalled in the opposite direction, these pins
may be bent and eventually broken and
knocked out due t o hitting stationary objects
or from thrown stones on off-road bikes. Be
