CLUTCH
Adjust the clearance (A) between the clutch booster push
rod and piston as follows:
(1) Measure the dimension (B) between the master cylinder
end face and piston.
NOTE
To obtain (B), first take measurement with a square placed
on the master cylinder end face. Then, subtract the thick-
ness of the square to arrive at (B).
(2) Obtain the dimension (C) between the clutch booster
mounting surface on the master cylinder and the end
face.

(3) Measure the dimension (D) between the master cylinder
mounting surface on clutch booster and the push rod
end.
NOTE
To obtain (D), first take measurement with a square placed
on the clutch booster. Then, subtract the thickness of
the square to arrive at (D).
(4) Using the measured values obtained in (1) through (3),
obtain the clearance (A) between the clutch booster push
00002196
rod and piston.
[When the clutch booster negative pressure of 66.7 kPa
(9.7 psi) is applied, the clearance (A) becomes 0.1 to
0.3 mm (-0039 to .0118 in.).]
