PREPARATION FOR SERVICE
AWARNING
Stop the eng ine when refueling or servicing the fuel sys-
tem. Do not smoke or allow open lIame or sparks near
gasoline. Gasoline is extremely flammable and highly
explosive, which could result in death or serious injury.
(00002a)
Good preparation is very important for efficient service work.
A clean work area at the start of each job will allow you to per-
form the repair as easily and quickly as possible, and will
reduce the incidence of misplaced tools and parts . A motorcy-
cle that is excessively dirty should be cleaned before work
starts. Cleani ng will occasionally uncover sources of trouble ,
Tools. instruments and any parts needed for the job should be
gathered before work is started. Interrupting a job to locate
tools or parts is a distraction and causes needless delay. See
APPENDIX A-TOOLS for equipment required for special ser-
vice work.
NOTE
• To avoid unnecessary disassembly. carefully read all rel-
ative service information before repair work is started.
• In ligure legends. the number which follows the name of
a part indicates the quantity necessary for one complete
essemoty:
SERVICE BULLETINS
In addition to the informa tion presented in this Service
Manual. Harfey-Davidson Motor Company will periodically
issue Service Bulletins to Harley dealers. Service Bulletins
