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.

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.

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.

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.

Make certain that the oil level indicated on the dip-stick is between the upper and lower marks. Insertthe dipstick carefully to avoid bending it.
lf the level has dropped close to the lower mark,add oil until it reaches the upper mark.

you the oil's SAE viscosity or weighl. Select the oil for
your vehicle according to this chart:
Ambient Temperature
100 F

An oil with a viscosity of 5 W - 30 is preferred for
improved fuel economy and year-round protection in
the vehicle. You may use a 10 W - 30 oil if the climate in
your area is limited to the temperature range shown on
the chart.
