Piston Rings
To measure end gap, insert piston ring (3) into cylinder bore and
then measure the gap by using thickness gauge (2).
If measured gap is out of specification, replace ring.
NOTE:
Decarbon and clean top of cylinder bore before inserting pis-
ton ring.

Crank Pin and Connecting Rod Bearings

Inspect crank pin for uneven wear or damage. Measure crank pin
for out-of-round or taper with a micrometer. If crank pin is dam-
aged, or out-of-round or taper is out of limit, replace crankshaft or
regrind crank pin to undersize and use undersize bearing.

Out-of-round and taper limit: 0.01 mm (0.0004 in.)

Rod bearing:
Inspect bearing shells for signs of fusion, pitting, burn or flaking
and observe contact pattern. Bearing shells found in defective
condition must be replaced.
Two kinds of rod bearing are available; standard size bearing and
0.25 mm undersize bearing. To distinguish them, 0. 25 mm under-
size bearing has the stamped number (US025) on its backside as
indicated in figure, but standard size one has no number.

Rod bearing clearance:
1) Before checking bearing clearance, clean bearing and crank
pin.
2) Install bearing in connecting rod and bearing cap.
3) Place a piece of gaging plastic (1) to full width of crankpin as
contacted by bearing (parallel to crankshaft), avoiding oil hole.
4) Install rod bearing cap (1) to connecting rod.
When installing cap, be sure to point arrow mark (2) on cap to
crankshaft pulley side (3), as shown in figure. After applying
engine oil to rod bolts, tighten cap nuts to specified torque. DO
NOT turn crankshaft with gaging plastic installed.

5) Remove cap and using a scale (2) on gaging plastic (1) enve-
lope, measure gaging plastic width at the widest point (clear-
ance).
If clearance exceeds its limit, use a new standard size bearing
and remeasure clearance.

a new standard size bearing, regrind crankpin to undersize
and use 0.25 mm undersize bearing.
ASSEMBLY
NOTE:
Two sizes of piston are available as standard size spare part
so as to ensure proper piston-to-cylinder clearance. When
installing a standard size piston, make sure to match piston
with cylinder as follows.
a) Each piston has stamped number 1 or 2 as shown. It represents
outer diameter of piston.
b) There are also stamped numbers of 1 and 2 on the cylinder block
as shown. The first number represents inner diameter of No.1
cylinder, the second number of No.2 cylinder, the third number
of No.3 cylinder and the fourth number of No.4 cylinder.

correspond. That is, install number 2 stamped piston to cylinder
which is identified with number 2 and a number 1 piston to cylin-
der with number 1.

Also, a letter A, B or C is stamped on piston head but ordinarily
it is not necessary to discriminate each piston by this letter.
1) Install piston pin to piston (1) and connecting rod (3):
After applying engine oil to piston pin and piston pin holes in pis-
ton and connecting rod, fit connecting rod to piston as shown in
figure and insert piston pin to piston and connecting rod, and
install piston pin circlips.
NOTE:
Circlip should be installed with its cut part facing either up
or down as shown in figure.
2) Install piston rings to piston:

As indicated in figure, 1st and 2nd rings have “RN” or “R” mark
respectively. When installing these piston rings to piston, di-
rect marked side of each ring toward top of piston.

1st ring (1) difffers from 2nd ring (2) in thickness, shape and
color of surface contacting cylinder wall.
Distinguish 1st ring from 2nd ring by referring to figure.

When installing oil ring (3), install spacer first and then two
rails.
3) After installing three rings (1st, 2nd and oil rings), distribute their
end gaps as shown in figure.

A: Crankshaft pulley side
B: Flywheel side
6A1-62 ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE)
INSTALLATION OR CONNECTION
1) Apply engine oil to pistons, rings, cylinder walls, connecting rod
bearings and crankpins.
NOTE:
Do not apply oil between connecting rod and bearing or be-
tween bearing cap and bearing.
2) Install guide hoses over connecting rod bolts.
These guide hoses protect crankpin and threads of rod bolt from
damage during installation of connecting rod and piston assem-
bly.
3) When installing piston and connecting rod assembly into cylin-
der bore, point arrow mark on piston head to crankshaft pulley
side.
4) Install piston and connecting rod assembly into cylinder bore.
Use special tool (Piston ring compressor) to compress rings.
Guide connecting rod into place on crankshaft.
Using a hammer handle, tap piston head to install piston into
bore. Hold ring compressor firmly against cylinder block until all
piston rings have entered cylinder bore.
