Flywheel
If ring gear is damaged, cracked or worn, replace flywheel.
If the surface contacting clutch disc is damaged, or exces-
sively worn, replace flywheel.
Check flywheel for face runout with a dial gauge.
If runout exceeds its limit, replace flywheel.
Flywheel runout
Limit : 0.2 mm (0.0079 in.)
Sensor Plate
Check sensor plate for crack or damage. If malcondition is
found, replace it.
Cylinder Block
Distortion of gasketed surface
Using straightedge and thickness gauge, check gasketed
surface for distortion and, if flatness exceeds its limit, correct
it.
Cylinder block flatness
Limit : 0.05 mm (0.0020 in.)
Honing or reboring cylinders
1) When any cylinder needs reboring, all other cylinders must
also be rebored at the same time.
2) Select oversized piston according to amount of cylinder
wear.

On-Vehicle Service
Accelerator cable adjustment
1) With throttle valve closed, check accelerator pedal play
which should be within following specification.
If measured value is out of specification, adjust it to specifi-
cation with cable adjusting nut (1).
Accelerator pedal play
“a” : 2 – 7 mm (0.08 – 0.27 in.)
2) With accelerator pedal depressed fully, check clearance
between throttle lever (2) and lever stopper (3) (throttle
body) which should be within following specification.
If measured value is out of specification, adjust it to specifi-
cation by changing height of pedal stopper bolt (1).
Accelerator cable adjustment clearance
(With pedal depressed fully)
“a” : 0.5 – 2.0 mm (0.02 – 0.07 in.)
Idle speed / idle air control (IAC) duty inspection
Before idle speed / IAC duty check, make sure of the following.
Lead wires and hoses of Electronic Fuel Injection and engine
emission control systems are connected securely.
Accelerator cable has some play, that is, it is not tight.
Valve lash is checked and adjusted according to mainte-
nance schedule.
Ignition timing is within specification.
All accessories (wipers, heater, lights, A/C, etc.) are out of
service.
Air cleaner has been properly installed and is in good condi-
tion.
No abnormal air inhaling from air intake system.
After above items are all confirmed, check idle speed and IAC
duty as follows.
NOTE:
Before starting engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
vehicle), and set parking brake and block drive wheels.
