3. VALVE GUIDE
1) Check the clearance between valve guide and stem.
The clearance can be checked by measuring the outside
diameter of valve stem and the inside diameter of valve
guide with outside and inside micrometers respectively.
Clearance between the valve guide and valve stem:
Standard
Intake
0.035—0.062 mm (0.0014—0.0024 in)
Exhaust
0.040—0.067 mm (0.0016—0.0026 in)
Limit
0.15 mm (0.0059 in)
Valve guide inner diameter:
6.000—6.012 mm (0.2362—0.2367 in)
Valve stem outer diameters:
Intake
5.950—5.965 mm (0.2343—0.2348 in)
Exhaust
5.945—5.960 mm (0.2341—0.2346 in)
G2M0150
2) If the clearance between valve guide and stem exceeds
the specification, replace guide as follows:
(1) Place cylinder head on ST1 with the combustion
chamber upward so that valve guides enter the holes
in ST1.
(2) Insert ST2 into valve guide and press it down to
remove valve guide.

(4) Before installing new oversize valve guide, make
sure that neither scratches nor damages exist on the
inside surface of the valve guide holes in cylinder head.
(5) Put new valve guide, coated with sufficient oil, in
cylinder, and insert ST1 into valve guide. Press in until
the valve guide upper end is flush with the upper sur-
face of ST2.

(6) Check the valve guide protrusion.
Valve guide protrusion: L
12.0—12.4 mm (0.472—0.488 in)
(7) Ream the inside of valve guide with ST. Gently
rotate the reamer clockwise while pressing it lightly into
valve guide, and return it also rotating clockwise. After
reaming, clean valve guide to remove chips.
ST 499767400 VALVE GUIDE REAMER
CAUTION:
Apply engine oil to the reamer when reaming.
If the inner surface of the valve guide is torn, the
edge of the reamer should be slightly ground with an
oil stone.
If the inner surface of the valve guide becomes lus-
trous and the reamer does not chips, use a new reamer
or remedy the reamer.
(8) Recheck the contact condition between valve and
valve seat after replacing valve guide.

B: POINTS TO CHECK
1) Check striker for bending or abnormal wear.
2) Check safety lever for improper movement.
3) Check other levers and spring for rust formation and
unsmooth movement.
G5M0141
C: INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
With buffer protruding about 18 mm (0.71 in) beyond
radiator panel, make sure that:

No clearance exists between buffer and inner hood.

Hood main lock is applied when hood is released at
a height of approximately 10 cm (3.94 in) above the
closed position.
G5M0142
NOTE:

Align the center of striker with lock during installation.
Make sure safety lever is properly caught by striker under
the hood’s own weight.

Route hood lock release cable and hold with clips.

After installing release cable, ensure it operates
smoothly.

Apply grease to sliding surfaces of parts.
B5M0268A
D: ADJUSTMENT
1) Fore-aft and left-right adjustments
Loosen striker mounting bolts and adjust fore-and-aft posi-
tion of striker.
CAUTION:
Do not adjust striker position using the lock. Doing so
may result in a misaligned front grille.
2) Up-down adjustment
Make up-and-down adjustment of striker only when hood
does not properly contact buffer or hood is not flush with
fender, or when release cable does not properly operate.
Adjustment can be made by adjusting the stroke length of
striker after lock assembly mounting screws are removed.

3. DEEP DAMAGE SUCH AS A BREAK OR HOLE
THAT REQUIRES FILLING
Much of the peripheral grained surface must be sacrificed
for repair, and the degree of restoration is not really worth
the expense. (The surface, however, will become almost
flush with adjacent areas.)
Recommended repair kit: PP Part Repair Kit (NRM)
Process
No.Process name Job contents
1 Bumper removal Remove bumper as required.
2 Parts removal Remove parts built into bumper as required.
3 Bumper placementPlace bumper on a paint work table as required.
It is recommended that contour of work table
accommodates internal shape of bumper.
G5M0164
4 Surface preparationRemove dust, oil, etc. from areas to be repaired and surrounding areas, using a suitable solvent
(NRM No. 900 precleno, white gasoline, or alcohol).
5 CuttingIf nature of damage are cracks or holes, cut a
guide slit of 20 to 30 mm (0.79 to 1.18 in) in
length along the crack or hole up to the bumper’s
base surface. Then, bevel or“vee-out”the
affected area using a knife or grinder.
G5M0165
6 Sanding (I) Grind beveled surface with sand paper (#40 to #60) to smooth finish.
7 Cleaning Clean the sanded surface with the same solvent as used in process No. 4.
8 Temporary weldingGrind the side just opposite the beveled area with sand paper (#40 to #60) and clean using a sol-
vent.
Temporarily spot-weld the side, using a PP welding rod and heater gun.
G5M0166
NOTE:

Do not melt welding rod until it flows out. This results in reduced strength.

Leave the welded spot unattended until it cools completely.
