General Description
MECHANICAL
8. ENGINE MOUNTING
C: CAUTION
•Wear work clothing, including a cap, protective
goggles and protective shoes during operation.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust and dirt.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
•Be careful not to burn yourself, because each
part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shop jacks or rigid racks at the specified
points.
•Before disconnecting connectors of sensors or
units, be sure to disconnect the ground cable from
the battery.
•All parts should be thoroughly cleaned, paying
special attention to engine oil passages, pistons
and bearings.
•Rotating parts and sliding parts such as piston,
bearing and gear should be coated with oil prior to
assembly.
•Be careful not to let oil, grease or coolant contact
the timing belt, clutch disc and flywheel.
•All removed parts, if to be reused, should be re-
installed in the original positions and directions.
•Bolts, nuts and washers should be replaced with
new ones as required.
•Even if necessary inspections have been made
in advance, proceed with assembly work while
making rechecks.
•Remove or install the engine in an area where
chain hoists, lifting devices, etc. are available for
ready use.
•Be sure not to damage coated surfaces of body
panels with tools, or not to stain seats and windows
with coolant or oil. Place a cover over fender, as re-
quired, for protection.
•Prior to starting work, prepare the following:
Service tools, clean cloth, containers to catch cool-
ant and oil, wire ropes, chain hoist, transmission
jacks, etc.
•Lift-up or lower the vehicle when necessary.
Make sure to support the correct positions.

Cylinder Head
MECHANICAL
3) Measure the flatness of the cylinder head sur-
face that mates with crankcase using a straight
edge (A) and thickness gauge (B).
Flatness:
Standard
0.02 mm (0.0008 in)
Standard height of cylinder head:
124±0.05 mm (4.88±0.0020 in)
NOTE:
Uneven torque for the cylinder head nuts can
cause warping. When reinstalling, pay special at-
tention to the torque so as to tighten evenly.
2. VALVE SEAT
Inspect the intake and exhaust valve seats, and
correct the contact surfaces with a valve seat cutter
if they are defective or when valve guides are re-
placed.
Valve seat width W:
Intake
Standard
1.0 mm (0.039 in)
Exhaust
Standard
1.5 mm (0.059 in)
3. VALVE GUIDE
1) Check the clearance between valve guide and
stem. The clearance can be checked by measuring
respectively the outer diameter of valve stem and
inner diameter of valve guide with a micrometer.
Clearance between the valve guide and valve
stem:
Standard
Intake
0.030 — 0.057 mm (0.0012 — 0.0022 in)
Exhaust
0.040 — 0.067 mm (0.0016 — 0.0026 in)
2) If the clearance between valve guide and stem
exceeds the standard, replace the valve guide or
valve itself whichever shows greater amount of
wear or damaged and etc. See the following proce-
dure for valve guide replacement.
Valve guide inner diameter:
5.500 — 5.512 mm (0.2165 — 0.2170 in
Valve stem outer diameters:
Intake
5.455 — 5.470 mm (0.2148 — 0.2154 in)
Exhaust
5.445 — 5.460 mm (0.2144 — 0.2150 in)
(1) Place the cylinder head on ST1 with the
combustion chamber upward so that valve
guides fit the holes in ST1.
(2) Insert the ST2 into valve guide and press it
down to remove the valve guide.
