FASTENERS
Proper fastener selection and installation is important to ensure the motorcycle
operates as designed and can be serviced efficiently. The choice of original equipment
fasteners is not arrived at by chance. Make sure replacement fasteners meet all the
same requirements as the originals
Many screws. Bolts and studs are combined with nuts to secure particular
components. to indicate the size of a nut. Manufactures specify the internal diameter
and the thread pitch
The measurement across two flats on a nut or bolt indicates the wrench size
WARNING
Do not install fasteners with a
strength classification lower than
what was originally installed by the
manufacturer doing so may cause
equipment failure and or damage
Torque Specifications
The material used in the manufacturing of the EV may be subjected to uneven
stresses if the fasteners of the various subassemblies are not installed and tightened
correctly. Fasteners that are improperly installed or work loose can cause extensive
damage. it is essential to use an accurate torque wrench as described in this chapter
Self-Locking Fasteners
Several types of bolts. Screws and nuts incorporate a system that creates
interference between the two fasteners. Interference is achieved in various ways. The
most common types are the nylon insert nut and a dry adhesive coating on the threads
of a blot.
Self-locking fasteners offer greater holding strength than standard fasteners, which
improves their resistance to vibration. All self-locking fasteners cannot be reused. The
