BLEEDING THE HYDRAULIC CLUTCH
SYSTEM (FJR1300AS)
WARNING
EWA13000
Bleed the hydraulic clutch system whenever:
• the system was disassembled,
• a clutch hose was loosened or removed,
• the clutch fluid level is very low,
• clutch operation is faulty.
NOTE:
• Before bleeding the hydraulic clutch system,
shift the transmission into neutral to engage
the clutch.
• Be careful not to spill any clutch fluid or allow
the clutch fluid reservoir to overflow.
• When bleeding the hydraulic clutch system,
make sure that there is always enough clutch
fluid in the reservoir before pumping out the flu-
id using the vacuum/pressure gauge set. Ig-
noring this precaution could allow air to enter
the hydraulic clutch system, considerably
lengthening the bleeding procedure.
• If bleeding is difficult, it may be necessary to let
the clutch fluid settle for a few hours. Repeat
the bleeding procedure when the tiny bubbles
in the hose have disappeared.
1. Remove:
• Air filter case
Refer to “GENERAL CHASSIS” on page 4-1.
• Rear wheel
Refer to “REAR WHEEL” on page 4-25.
