Cylinder Block
MECHANICAL
E: INSPECTION
1. CYLINDER BLOCK
1) Visually check for cracks and damage. Especial-
ly, inspect the important parts using liquid pene-
trant tester.
2) Check the oil passages for clogging.
3) Inspect the crankcase surface that mates with
cylinder head for warping by using a straight edge.
Standard height of cylinder block:
202 mm (7.95 in)
2. CYLINDER AND PISTON
1) The cylinder bore size is stamped on the front
upper face of the cylinder block.
NOTE:
•Measurement should be performed at a temper-
ature of 20°C (68°F).
•Standard sized pistons are classified into two
grades, “A” and “B”. These grades should be used
as guide lines in selecting a standard piston.
Standard diameter:
A: 89.205 — 89.215 mm (3.5120 — 3.5124 in)
B: 89.195 — 89.205 mm (3.5116 — 3.5120 in)
2) How to measure the inner diameter of each cyl-
inder:
Measure the inner diameter of each cylinder in both
the thrust and piston pin directions at the heights as
shown in the figure, using a cylinder bore gauge.
NOTE:
Measurement should be performed at a tempera-
ture of 20°C (68°F).
Cylindricality:
Standard
0.030 mm (0.0012 in)
Out-of-roundness:
Standard
0.010 mm (0.0004 in)
3) When the piston is to be replaced due to general
or cylinder wear, determine a suitable sized piston
by measuring the piston clearance.

Brake Line
PERIODIC MAINTENANCE SERVICES
13.Brake Line
A: INSPECTION
1. BRAKE LINE
1) Check for scratches, swelling, corrosion, traces
of fluid leakage on the brake hoses or pipe joints.
2) Check the possibility of adjacent parts interfering
with brake pipes/hoses during driving, and loose
connections/clamps.
3) Check any trace of fluid leakage, scratches, etc.
on master cylinder, wheel cylinder and pressure
control valve.
NOTE:
•When the brake fluid level in the reservoir tank is
lower than specified limit, the brake warning light
on the combination meter will come on.
•Visually check the brake hose for damage. (Use
a mirror where it is difficult to see)
2. SERVICE BRAKE
1) Check the free play of brake pedal with pulling
up the force of less than 10 N (1 kgf, 2 lb).
Brake pedal free play (Pulling up direction of
pedal)
0.5 — 2.0 mm (0.02 — 0.08 in)
2) If the free play is out of specifications above, ad-
just the brake pedal as follows.
(1) Make sure the engine is off. (No vacuum is
applied to brake booster.)
(2) There should be play between brake boost-
er clevis and pin at brake pedal installing por-
tion. [Pulling up the brake pedal pad with a force
of less than 10 N (1 kgf, 2 lb) to a stroke of 0.5
to 2.0 mm (0.02 to 0.08 in).]
(3) If there is no free play between clevis pin
and clevis, turn brake switch adjusting nut until
the clearance between stopper and screw of
brake switch becomes 0.8 mm (0.031 in).

(2) Front brake pipe
