BRAKES 5-9
EXCESSIVE PEDAL TRAVEL INSPECTION
1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 30 kg (66
lbs) load, measure brake pedal to wall (dash panel silencer)
clearance “a”.
If clearance “a” is less than specification, the most possible
cause is either rear brake shoes are worn out beyond limit or
air is in lines.
Should clearance “a” remain less than specification even
after replacement of brake shoes and bleeding of system,
other possible but infrequent cause is malfunction of rear
brake shoe adjusters or booster push rod length out of
adjustment.
–Bleed brake system. Refer to “AIR BLEEDING OF BRAKE
SYSTEM”.
–Remove brake drums for adjuster inspection. (Refer to
“REAR BRAKE”.) If defective, correct or replace.
Clearance “a” between brake pedal and dash panel
silencer
LH steering vehicle : over 135 mm (5.32 in.)
RH steering vehicle : over 140 mm (5.52 in.)
FRONT BRAKE PAD INSPECTION
Inspect pad linings (1) periodically according to maintenance
schedule whenever wheels are removed (for tire rotation or other
reason). Take a look through each end (or hole) of caliper and
check lining thickness of outside and inside pads.
If lining is worn and its thickness (“a” in figure) is less than limit, all
pads must be replaced at the same time.
Front brake pad thickness “a” (lining thickness)
Standard : 10 mm (0.40 in.)
Limit : 2 mm (0.08 in.)
BRAKE DISC INSPECTION
Refer to “BRAKE DISC” for inspection point and procedure.

Valve Guides
Using a micrometer and bore gauge, take diameter readings on
valve stems and guides to check stem-to-guide clearance. Be
sure to take reading at more than one place along the length of
each stem and guide.
If clearance exceeds limit, replace valve and valve guide.

If bore gauge is not available, check end deflection of valve stem
with a dial gauge instead.
Move stem end in directions (1) and (2) to measure end deflec-
tion.

Valve Springs
Referring to data given below, check to be sure that each
spring is in sound condition, free of any evidence of break-
age or weakening. Remember, weakened valve springs can
cause chatter, not to mention possibility of reducing power
output due to gas leakage caused by decreased seating
pressure.

skewness in terms of clearance between end of valve spring
and square. Valve springs found to exhibit a larger clearance
than limit given below must be replaced.

Use a dial gauge to read displacement in axial (thrust) direction of
crankshaft.
If its limit is exceeded, replace thrust bearing with new standard
one or oversize one to obtain standard thrust play.
Crankshaft thrust play
Standard : 0.11 – 0.31 mm (0.0043 – 0.0122 in.)
Limit : 0.35 mm (0.0138 in.)
Out-of-round and taper (uneven wear) of journals
An unevenly worn crankshaft journal shows up as a difference in
diameter at a cross section or along its length (or both). This dif-
ference, if any, is determined by taking micrometer readings. If
any one of journals is badly damaged or if amount of uneven wear
in the sense explained above exceeds its limit, regrind or replace
crankshaft.

Main Bearings
General information
Service main bearings are available in standard size and
0.25 mm (0.0098 in.) undersize, and each of them has 5
kinds of bearings differing in tolerance.
Upper half of bearing (1) has an oil groove (2) as shown in
figure.
Install this half with oil groove to cylinder block.
Lower half of bearing does not have an oil groove.
Visual inspection
Check bearings for pitting, scratches, wear or damage.
If any malcondition is found, replace both upper and lower halves.
Never replace either half without replacing the other half.
Main bearing clearance
Check clearance by using gaging plastic according to the follow-
ing procedure.
1) Remove bearing caps.
2) Clean bearings and main journals.
