NOTE: End play for th€ connecting rods and crankshaft
should be inspected betore removing the crankshaft.

Remove the baffle plate.
Turn the crankshaft so No.2 and 3 crankpins ar€ at
the bottom.
Remove the right side cover.

CAUTION: To prevent warPag€, unscrew ths bohr
in 3equoncg 1/3 turn at a tim€; rspeat ihe sgquanco
until all bolts are loos€ned.
Remove the cap bridge {818C1 engine only} and
main caps/bearings. Keep all caps/bearings in order.

EndPlay
NOTE; End play should be inspected before removing
crankshaft.
Push the crank firmly awav from the dial indicator, and
zero the dial against the end of the crank. Then pull the
crank firmly back toward the indicator; dial reading
should not exceed service limit.
Crankshaft End Play:
Standard (New): 0.10 - 0.35 mm
(0.04 - 0.01i| inl
S€rvic€ Limit 0.i15 mm (0.018 inl
. lf end play is excessive, inspect the thrust wash€rs
and thrust surface on the crankshaft. Replace pans as
necessary.
NOTE:
Thrust washer thickness is fixed and must not be
changed either by grinding or shimming.
Thrust washers are installed with grooved sides fac-
ing outward.
Crankshaft
lnspection
. Clean the crankshatt oil passages with pipe cleaners
or a suitable brush.
. Check the keyway and threads.
Alignment
Measure runout on all main journals to make sure the
crank is not bent.
The differ€nce between measurements on each jour-
nal must not be more than the service limit.

Measure cylinder bores as shown on page 7-13.
lf the block is to be reused, hone the cylinders and
remeasure the bores.
Hone cylinder bores with honing oil and a fine (400
grit) stone in a 60 degree cross-hatch pattern.
NOTE:
. Use only a rigid hone with 400 grit or finer stone
such as Sunnen, Ammco, or equivalent.
a Do not use stones that are worn or broken.
When honing is complete, thoroughly clean the
cylinder block of all metal panicles. Wash the cylin-
der bores with hot soapy water, then dry and oil
immediately to prevent rusting.
NOTE: Never use solvent, it will only redistribute
the grit on the cylinder walls.
lf scoring or scralches are still present in cylinder
bores after honing to the service limit, rebore the
engine block.
NOTEr Some light venical scoring and scratching is
acceptable if it is not deep enough to catch your fin-
gernail and does not run the full length of the bore.
CYLINDER HONE
. After honing, clean the cylinder thoroughly with
soapy water.
. Only scored or scratched cylinder bores must be
noneo.

Piston
lnstallation
'1.
Before installing the piston, apply a coat ofengine oil to the ring grooves and cylinder bores.
lf the crankshaft is already installed:
. Remove the connecting rod caps and slip short
sections of rubber hose ove. the threaded ends
of the connecting rod bolts.
a Install 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.
Stop after the ring compressor pops free and
check the connecting rod-to-crank journal align-
ment before tapping piston into place.
. Install the rod caps with bearings, then torque
the nuts,

lf the crankshaft is not installed:
o Remove the rod caps and bearings. install the
ring compressor, then position the piston in the
cylinder and tap it in using the wooden handle of
a nammer.
. Position all Distons at toD dead center.
CONNECTING RODOIL HOI-E (Br8Bl onginelThe arrow must facethe timing belt sideof the engine. Theconnecting rod oil holemust lace the intak€manifold {81881 €ngine).
NOTE: Maintain downward force on the ring com-
pressor to prevent rings from expanding before
entering the cylinder bore,
BING COMPRESSORUse the wooden handleof a hammer to push ortap the piston into thecylinder bore.
Piston Rings
Replacement
1.Using a ring expander, remove old piston rings.
Clean all ring g.ooves thoroughly.
NOTE:
. Use a squared-oJf broken ring or ring groove
cleaner with blade to fit piston grooves.
. Top ring groove is 1.0 mm (0.039 in) wide, sec-
ond groove is 1.2 mm (0.047 in) wide. and oil
ring groove is 2.8 mm (0.110 in) wide.. File down blade if necessary.
CAUTION: Do not use a wire brush to cloan thr
ring lands, or cut ring lands dsopo. with cl€aning
tool.
NOTE: lf the piston is to be separated from the con-
necting rod, do not install new rings yet.
Install new rings in the prope. sequence and posi-
tion (see page 7-18).
NOTE: Do not use old piston rings.

11.lnstallthe oil screen.
Installthe oil pan.
NOTE: Clean the oil pan gasket mating surfaces.
Tighten the bolts as shown below.

NOTE: Tighten the bolts and nuts in two steps and
toroue the bolts in a crisscross pattern
