WARNING
EW1D71006
• Before installation, all internal clutch com-
ponents must be cleaned and lubricated

to swell and distort.
• Whenever a clutch release cylinder is dis-
assembled, replace the piston seal.

INSTALLING THE CLUTCH RELEASE
CYLINDER
1. Install:
• Copper washers
• Clutch pipe “1”
• Clutch pipe union bolt “2”
WARNING
EWA1D77009
Proper clutch pipe routing is essential to in-
sure safe vehicle operation. Refer to “CABLE
ROUTING (for XV19S(C)/ XV19M(C)/
XV19CTS(C)/ XV19CTM(C))” on page 2-51
and “CABLE ROUTING (for XV19CS(C)/
XV19C(C))” on page 2-67.
CAUTION:
EC1D71005
When installing the clutch pipe onto the
clutch release cylinder, make sure the pipe
“a” touches the projection “b” on the clutch
release cylinder.
2. Fill:
• Clutch master cylinder reservoir
(with the specified amount of the recom-
mended clutch fluid)
WARNING
EWA13370
• Use only the designated clutch fluid. Other
clutch fluids may cause the rubber seals to
deteriorate, causing leakage and poor
clutch performance.
• Refill with the same type of clutch fluid that
is already in the system. Mixing clutch flu-
ids may result in a harmful chemical reac-
tion, leading to poor clutch performance.
• When refilling, be careful that water does
not enter the clutch fluid reservoir. Water
will significantly lower the boiling point of
the clutch fluid and could cause vapor lock.
CAUTION:
ECA13420
Clutch fluid may damage painted surfaces or
plastic parts. Therefore, always clean up any
spilt clutch fluid immediately.
NOTE:
In order to ensure a correct reading of the clutch
fluid level, make sure that the top of the reservoir
is horizontal.
3. Bleed:
• Clutch system
Refer to “BLEEDING THE HYDRAULIC
CLUTCH SYSTEM” on page 3-15.
4. Check:
• Clutch fluid level
Below the minimum level mark “a”
→
Add the
recommended clutch fluid to the proper level.
Refer to “CHECKING THE CLUTCH FLUID
LEVEL” on page 3-14.
