release cylinder and all the circumferential surfaces of the
piston and piston cup, insert the piston and piston cup into
the cylinder.

INSPECTION
RELEASE CYLINDER
Check the inside wall surface of the release cylinder for rust
and damage.
Using a cylinder gauge, measure the inside diameter of the
release cylinder at about three positions (the deepest, middle
and brim positions). If the clearance from the outside diameter
of the piston exceeds the limit, replace the release cylinder
as an assembly.
Limit: 0.15 mm

4.
Measure the clutch pedal play.
Standard value (B): 1 – 3 mm
5.
If the clutch pedal play is not within the standard value,
loosen the setting nut and move the push rod to adjust.
Caution
Do not push in the master cylinder push rod at this
time.
6.
After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between the clutch pedal (the face of
the pedal pad) and the toeboard when the clutch is
disengaged are within the standard value ranges.
Standard value (C): 6– 13 mm
Standard value (D): 85 mm or more
7.
If the clutch pedal free play and the distance between
the clutch pedal and the toeboard when the clutch is
disengaged do not agree with the standard values, it
is probably the result of either air in the hydraulic system
or a faulty master cylinder or clutch. Bleed the air, or
disassembly and inspect the master cylinder or clutch.
8.
Turn back the carpet, etc.
