(b) Align the oil holes of a new bushing and the connecting
rod.
(c) Using SST and a press, press in the bushing.
SST 09207−76010
(d) Using a pin hole grinder, hone the bushing to obtain the
standard specified clearance (see step 14 above) be-
tween the bushing and piston pin.
(e) Check the piston pin fit at normal room temperature. Coat
the piston pin with engine oil, and push it into the connect-
ing rod with your thumb.
16. INSPECT CONNECTING ROD BOLTS
(a) Install the cap nut to the connecting rod bolt. Check that
the cap nut can be turned easily by hand to the end of the
thread.
(b) If the cap nut cannot be turned easily, measure the mini-
mum outside diameter of the connecting rod bolt with ver-
nier calipers.
Standard outside diameter:
7.80 − 7.90 mm (0.3071 − 0.3110 in.)
Minimum outside diameter:
7.60 mm (0.2992 in.)
HINT:
If the location of minimum diameter cannot be judged by
visual inspect ion, measure the outer diameter at the loca-
tion shown in the illustration.
If the outside diameter is less than limit, replace the con-
necting rod bolt and nut as a set.

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. REMOVE HIGH−TENSION CORDS WITH IGNITION
COILS (See page IG−1)
3. REMOVE SPARK PLUGS
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Compression pressure:
1,200 kPa (12.2 kgf/cm
2, 174 psi) or more
Minimum pressure:
1,000 kPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 15 psi) or less
(e) If the cylinder compression in 1 or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (c) for
cylinders with low compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS
