Clearance
1. Remove the connecting rod cap and bearing half.2. Clean the crankshaft rod journal and bearing halfwith a clean shop towel.
3. Place the plastigage across the rod journal.
4. Reinstall the bearing half and cap, and torque thenuts (818C5 engine: see page 7-19).

NOTE: Do not rotate the crankshaft during inspection.

lf the plastigage measures too wjde or too narrow,remove the upper half of the bearjng, install a new,complete bearing with the same color code (select
the color as shown in the rig ht column), andrecheck the clearance.
CAUTION: Do not file, shim, or scrape the bearingor the caps to adiust clearance.
It the plastigage shows the clearance is still incorrect,try the next larger or smaller bearing (the color listedabove or below that one), and check clearance again.
NOTEr It the proper clearance cannot be obtainedby using the appropriate larger or smaller bearings,replace the crankshaft and stan over.
Selection
CAUTION: lf the codes are indecipherable because ofan accumulation of dirt and dust, do not scrub themwith a wire brush or scraper. Clean them only with sol-vent or delergent.
Connecting Rod Code Location
A number has been stamped on the side of each con-necting rod as a code for the size of the big end. Use it,and the letters stamped on the crank lcodes for rod iour-nal size), to choose the correct bearinqs.

NOTE: End play for the connecting rods and crankshaft
should be inspected before removing the crankshaft.
1. Remove the oil pan, oil screen and the oil pump.

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.

NOTE:
. Clean the crankshaft oil passages with pipe cleanersor a suitable brush.
. Check the keyway and threads.

. Measure runout on all main journals to make sure thecrank as not bent.
. The difference between measurements on each ,our-nal must not be more than the service limit.

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.
