Piston Pins
lMeasure the diameter of the piston pin.
Piston Pin Diameter:
Standard lNewl: 20.996 - 21.000 mm
{0.8266 - 0.8268 in}
20.998 - 21.002 mm(0.8267 - 0.8268 in)
Inspection

Oversize:
2. Zeto the dial indicator to the piston pin diameter.
7-16
3. Measure the piston pin to piston clearance. lf the
piston pin clearance is greater than 0.024 mm
(0.0009 inL remeasure using an oversized piston pin.
NOIE: All replacement piston pins are oversize.
Piston Pin-to-Piston Clearance:
Standard lNewl: 0.010 - 0.017 mm
10.0004 - 0.0007 in)
Check the difference betlveen the piston pin diame-
ter and the connecting rod small end diameter.
Piston Pin-to-Connecting Rod Interference:
Standard (New): 0.015 - 0.032 mm(0.0006 - 0.0013 inl

Piston Rings
2.
Replacement
1.Using a ring expander, remove the old piston rings.
Clean all the ring grooves thoroughly with a
squared-off broken ring or a ring gtoove cleaner
with a blade to fit the piston grooves.
The top ring groove is 1.2 mm (0.042 in) wide, rhe
second ring groove is 1.2 mm (0.042 in) wide, and
the oil ring groove is 2.8 mm (0.11 in) wide. File
down a blade if necessary.
Do not use a wire brush to clean ring lands, or cutring lands deeper with cleaning tool.
3. Install the new rings in the proper sequence andposition (shown in the right column).
NOTE: lfthe piston is to be separated from the con-
necting rod, do not install new rings yet.

Installation
1. Apply a coat of engine oil to the ring grooves andcylinder bores.
It the crankshaft is already installed.
2. Set the crankshatt to BDC for each cylinder.3. Remove the connecting rod caps, and slip short sections of rubber hose over the threaded ends of theconnecting rod bolts.
4. lnstall the ring compressor, and check that the bear-ang is securely in place.
5. Position the piston in the cylinder, and tap it in usingthe wooden handle of a hammer. Maintain down-ward force on the ring compressor to prevent ringstrom expanding before entering the cylinder bore.6. Stop after the ring compressor pops free, and checkthe connecting rod-to-crank journal alignmentbefore pushing piston into place.
7. Install the rod caps with bearings, and torque theNUIS IO:

Installation
Apply a coat of engine oil to the main bearings androd bearings.
Insert the bearing halves in the cylinder block andconnect|ng rods.
Hold the crankshaft so the rod journals for cylindersNo.2 and No. 3 are straight down.
Lower the crankshaft into the block, seating the rodjournals into connecting rods No.2 and No.3.Install the rod caps and nuts finger tight.

Rotate the crankshaft clockwise, and seat the jour
nals into connecting rods No. 1 and No. 4, Install
the rod caps and nuts finger-tight. Install the capsso the bearing recess is on the same side as therecess an the rod.
Check the rod bearing clearance with plastigage(see page 7 8). then lorque the capnuts.

NOTE: Whenever any crankshaft or connecting rod
bearing is replaced, it is necessary after reassembly
to run the engine at idling speed until it reaches
normal operating temperature, then continue to run
it for approximatelY 15 minutes.
10.Clean and dry the right side cover mating surfaces.
Apply liquid gasket, part No. 08718 - 0001 or 08718
- 0003, evenly to the block mating surface of the
right side cover and to the inner threads of the bolt
holes. Install it on the cylind€r block

NOTE:
. Do not install the parts if five minutes or more
have elapsed since applying the liquid gasket.
Instead, reapply liquid gasket after removing the
old residue.
. After assembly, wait at least 30 minutes before
filling the engine with oil.

Engine Coolant Refilling and Bleeding (cont'dl
Mix the recommended antifreeze with an equal
amount of water in a clean container.

For best corrosion protection, the coolant con-
centration must be maintained year-round at50% minimum. Coolant concentrations less than
50% may not provide sufficient protection against
corrosion or freezing. Coolant concentrationsgreater than 60% will impair cooling efficiency
and are not recommended.
Do not use additional rust inhibitors or anti-rustproducts; they may not be compatible with the
coolant.

9. Pour coolant into the radiator uD to the base of the
filler neck. When pouring engine coolant. do not let
coolant spill on any electrical pans or the paint. lf
any coolant spills, rinse it oft immediately.
Start the engine, and let it run until it warms up (the
radiator fan comes on at least twice).
Turn off the engine. Check the level in the radiator,
add coolant if needed.
Put the radiator cap on tightly. then run the engine
again and check for leaks.
