Grankshaft
Removal (cont'dl
Use the wooden handle ot a hammer to drive the
pistons out.
CAUTION:
. Take care not to damage the contact surface ot
the metal gasket.
. When removing the piston/connecting rod, take
care not to hit the oil iet (818C1, 818C5 enginesl.
. ll the oil iet nozzle is damaged or bent, replace
the oil iet assembly {818C1, B18C5 engincs.
page 8-9).
Reinstall the rod bearings and caps after removing
each piston/connecting rod assembly.
l\4ark each piston/connecting rod assembly with its
cylinder number to avoid mixup on reassembly.
NOTE; The existing number on the connecting rod
does not indicate its position in the engine, it indi-
cates the rod bore size.
End Play
NOTE: End play should be inspected before removing
crankshaft.
Push the crank firmly away 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
{0.00'l - 0.014 inl
Service Limit: 0.45 mm 10.018 inl
. lf end play is excessive, inspect the thrust washers
and thrust surface on the crankshaft. Replace parts as
necessary.
NOTE:
. Thrust washer thickness is tixed and must not be
changed either by grinding or shimming.
. Thrust washers are installed with grooved sides fac-
ing outward.

Bore Honing
l/easure cylinder bores as shown on page 7-14.lf the block is to be reused, hone the cylinders andremeasure the bores.
Hone cylinder bores with honing oil and a fine (400
grat) stone in a 60 degree cross-hatch pattern.
NOTE:
. Use only a rigid hone with 400 grit or finer stonesuch as Sunnen, Ammco, or equivalent.a Do not use stones that are worn or oroKen.
When honing is complete, thoroughly clean thecylinder block of all melal particles. Wash the cylin-der bores with hot soapy water, then dry and oilimmediately to prevent rusting.
NOTE: Never use solvent, it wili only redistribute
the grit on the cylinder walls.
lf scoring or scratches are still present in cylinderbores after honing to the service limit, rebore theengine block.
NOTE: Some light vertical scoring and scratching isacceptable if it is not deep enough to catch your fin-gernail and does not run the full length ofthe bore.
NOTE:
. After honing, clean the cylinder thoroughly withsoapy water.o Only scored or scratched cylinder bores must behoned.

Installation
Bl881, 818C1 enginos:
lf the crankshaft is already installed
'1. Set the crankshaft to BDC for each cylinder.
2, Remove the connecting rod caps, and slip short sec-
tions of rubber hose over the threaded ends of the
connecting rod bolts.
3. Install the ring compressor, and check that the bear-
ing is securely in place.
4. Position the arrow facing the timing belt side of the
eng ine.
The arrow must facethe timing belt sideot the engine. Theconnecting rod oil holemust face the intakemanjfold (81881 engine).
CONNECTING ROOOIL HOLE {81881 enginel
Position the piston in the cylinder. and tap it in
using the wooden handle of a hammer.
NOTE; Maintain downward force on the ring com-pressor to prevent rings from expanding before
entering the cylinder bore.
6. Stop after the ring compfessor pops free, and check
the connecting rod-to-crank journal alignment
betore pushing piston in to place,
7.Check the connecting rod bearing clearance withplastigage {see page 7-9).
Apply engine oil to the bolt threads. then install the
rod caps with bearings,
Installthe nuts, and toroue it.

Piston Rings
Replacement
Using a ring expander, remove old piston rlngs.
Clean all ring grooves thoroughly.
o Use a squared-ofl broken ring or ring groove
cleaner with blade to fit piston grooves.
. lop 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 clean the
ring lands, or cut ring lands deeper with cleaning
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 proper sequence and posa-
tion (see page 7 21).
Do not use old piston rings.
PISTON RING
End Gap
Using a piston, push a new ring into the cvlinder
bore 15 - 20 mm 10.6 0.8 in) f rom the bottom.
2. N,4easure 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 bore
diameter against the wear limits on page 7-13.
lf the bore is over the service limit, the cylinder
block must be rebored.
