NOTE; All replacement piston pins are overslze.
2. Zero the dial indicator to the piston pin diameter'
Measure the diameter of the piston pin.

3. Measure the piston pin-to-piston clearance.
NOTE: Check the piston for distortion or cracks.
lf the piston pin clearance is greater than 0.024 mm
(0.0009 jn), remeasure using an oversized piston
pin.
Piston Pin-to-Piston Clearance:
Standard (New): 0.010 - 0.022 mm

Check the difference between the piston pin diame-
ter and the connecting rod small end diameter'

Piston Rings
End Gap
1.Using a piston, push a new ring into the cylinderbore 15 - 20 mm (0.6 - 0.8 in) from the bottom.
Measure the piston ring end-gap with a feeler gauge:
. lf the gap is too small, check to see if you have
the proper rings for your engine.. lf the gap is too large. recheck the cylinder borediameter against the wear limits on page 7-16,
lf the bore is over the service limit, the cvlinderblock must be rebored.

Replacement
1.Using a ring expander. remove the old piston rings.
Clean all ring grooves thoroughly.
NOTE:
. Use a squared-off broken ring or ring groove
cleaner with blade to fit piston grooves.
o Top ring groove is 1.0 mm (0.039 in)wide.. Second ring groove is 1.2 mm (0.047 in) wide.. Oil ring groove is 2,8 mm (0.11 in) wide.. File down the blade if necessary.
CAUTION: Do noi use a wire blush to clean ringlands. or cut ring lands deepol with cleaning tool.
NOTE: lfthe piston is to be separated from the con-necting rod, do not install new rings yet.
3. Install new rings in the proper sequence and posi-
taon (see page 7-22).
NOTE: Do not reuse old piston rings.

lnstallation
Before installing the pistons, apply a coat of
engine oil to the ring grooves and cylinder
bores.
lf the crankshaft is already installed:
. Set the crankshaft to BDC for each cylinder.
. Remove the connecting rod caps, and slip short
sections of rubber hose over the threaded ends
of the connecting rod bolts.
. lnstall the ring compressor. check that the bear-
ing is securely in place, then position the piston
in the cylinder, and tap it in using the wooden
handle of a hammer.
o Stop after the ring compressor pops free, and
check the connecting rod-to-crank journal align-
ment before pushing the piston into place
. Apply engine oil to the bolt threads. Install the
rod caps with bearings, and torque the nuts to:
815A2 engine:
40 N.m {,1.1 kgf.m, 30 lbf'ft|
D16Y5, D16Y7, D16Y8 engines:
31 N.m (3.2 kgf'm,23 lbf'ft)
lf the crankshaft is not installed:
. Remove the rod caps and bearings, install the ring
compressor, then position the piston in the cylin-
der, and tap it in using the wooden handle of a
hammer.
. Position all Distons at top dead center.

NOTE: Maintain downward force on the ring com-
pressor to prevent the rings from expanding before
entering the cylinder bore.

lnstallation
Before installing the crankshaft, apply a coat of
engine oil to the main bearings and rod bearings.
Insert the bearing halves into the cylinder block and
connecting rods.
Hold the crankshaft so the rod journals for cylinders
No.2 and No. 3 are straight down.
Lower the crankshaft into the block, seating the rod
journals into connecting rods No. 2 and No. 3, and
install the rod caps and nuts finger-tight.

Grooved sides faceoulward.Botate the crankshaft clockwise, seat journals into
connecting rods No, 1 and No.4, and install the rod
caps and nuts finger-tight.
NOTE: Install caps so the bearing recess is on the
same side as the recess in the rod.
Check rod bearing clearance with plastigage (see
page 7-11), then torque the capnuts. Apply engine
oil to the bolt threads.

NOTE: Reference numbers on connecting rod are
for big-end bore tolerance and do not indicate the
position of piston in the engine.
Line up the marks wheninstalling the connectrng rod
