Crankshaft Main Bearing Replacement
Main Bearing Clearance Inspection
1. To check main bea ring-to-jou rna I oil clearance.
remove the lower block and bearing halves (see
page 1 -12)..
2, Clean each main journal and bearing half witha
clean shop towel.
3. Place one strip of plastigage across each main
lou rnal.
4. Reinstallthe bearings and lower block, then torque
the bolts to 29 N.m {3.0 kgf.m,22 lbf.ft) + 56'.
NOTE: Do not rotate the crankshaft during
Inspeclton.
5. Remove the lower block and bearings again, and
measure the widest part of the plastigage.

\.
6. lf the plastigage measures too wide or too narrow,
remove the crankshaft. and remove the upper half
ofthe bearing. Install a new, complete bearing with
the same color code{s), and recheck the clearance.
Do not file, shim, or scrape the bearings or the caps
to adjust clearance.
7. lf the plastigage shows the clearance is still
incorrect, try the next larger or smaller bearing (the
color listed above or below that one), and check
again. lf the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.

3. Use the crank bore codes and crank journal codes
to select the appropriate replacement bearings
from the following table.
NOTE:. Color code is on the edge of the bearing.. When using bearing halves of different colors. it
does not matter which color is used in the top or
bottom.

Replacement
Rod Bearing Clearance lnspection
1. Remove the oil pump (see page 8-9).
2. Bemove the baffle plates (see step 6 on page 7-12).
3. Remove the connecting rod cap and bearing half.
4. Clean the crankshaft rod journal andbearinghalf
with a clean shop towel.
5. Place plastigage across the rod journal.
6. Reinstallthe bearing half and cap, and torque the
bolts to 20 N.m (2.0 kgf.m, 14lbf.ft) -l 90 ".
NOTE: Do not rotate the crankshaft during
inspection.
7. Remove the rod cap and bearing half, and measure
the widest part of the plastigage.

Piston Installation
lf the crankshaft is already installed
1. Setthe crankshaftto bottom dead center (BDC) for
each cylinder.
2. Remove the connecting rod caps, then install the
ring compressor, and check that the bearing is
securely in place,
3. Position the arrow {A) facing the cam chain side of
rne engtne.
Position the piston in the cylinder, and tap it in
using the wooden handle of a hammer (A).
N4aintain downward force on the ring compressor(B) to prevent the rings from expanding before
entering the cylinder bore.
Stop after the ring compressor pops free, and
check the connecting rod-to-crank journal
alignment before pushing the piston into place.
Check the connecting rod bearing clearance withplastigage (see page 7-8).
lnspect the connecting rod bolts (see page 7 241.
Apply engine oil to the bolt threads, then install the
rod caps with bearings. Torque the bolts to 20 N.m
{2.0 kgf m, 14 lbf ft) + 90'.

Engine Oil Filter (3/4-turn type)
1. Remove the oil filterwiththesDecial tool.
2. Inspect the threads {A) and rubber seal (B) on the
new filter. Wipe off the seat on the engine block,
then apply a light coat of oil to the filter rubber seal.
Use only filters with a built-in bypass system.
Installthe oilfilter by hand.
After the rubber seal seats, tighten the oil filter
clockwise with the special tool.

5. lf 4 numbers or marks (1 to 4 or V to VVVV) are
printed around the outside of the filter, use the
following procedure to tighten the filter.
. Spin the filter on until its seal lightly seats against
the block, and note which number or mark is at
the bottom.. Tighten the filter by turning it clockwise 3
numbers or marks from the one you noted. For
example, if number 2 is at the bottom when the
seal is seated, tighten the filter until the number 1
comes around the bottom.
