Glearance
1.To check main bearing-to-journal oil clearance.
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main jour-
na l.
NOTE: lf the engine is still in the car when you bolt
the main cap down to check clearance, the weight
of the crankshaft and flvwheel will flaften the plasti-
gage further than just the torque on the cap bolt.
and give you an incorrect reading. For an accurate
reading, support the crank with a jack under the
counterweights and check only one bearing at a
time,
Reinstall the bearings and caps, then torque the
bolts.

lf the plastigage measures too wide or too narrow,
(remove the engine if it's still in the car), remove the
crankshaft, and remove the upper half of the bear-
ing. Install a new. complete bearing with the same
color code {select the color as shown on the next
page), and rechsck the clearance.
CAUTION: Do nol fil€, shim, or scrape the bearings
or tho cap3 to adiust cleatanc€.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again
NOTE: lf the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.

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:

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.

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.

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.

. Check that the mating surfaces are clean and dry
before apPlying liquid gasket.
. Apply liquid gasket as an even bead, centered
between the edges ol the mating surface'
. To prevent leakage of oil, apply liquid gasket to
the inner threads of the bolt holes
. Do not install the parts if five minutes or more
have elapsed since applying the liquid gasket
lnstead, reapply liquid gasket after removing the
old residue
. After assembly, wait at least 30 minutes before
filling the engine with oil.

Inspection
1.Remove the oil jet (see page 8-3) and inspect it asfollows.
Make sure that a 1.1 mm (0.04 in) diameter drillwill go through the nozzte hole (j.2 mm (0.05 in)diameter).
Insert the other end of the same 1.1 mm (0.04 in)drill into rhe oil intake (i.2 mm (0.05 in) diame_ter).
Make sure the check ball moves smoothly andhas a stroke of approximately 4.0 mm (0.16 in).Check the oil jet operation with an air nozzle. ltshould take at least 200 kPa (2.0 kgf/cm,, 28 psi)to unseat the check ball.
NOTE: Replace the oil jet assembly if the nozzlers damaged or bent.
