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.

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.

Drain the engine oil (see page 8-5).
lf the engine is still in the vehicle, remove the
subframe.
-1 Attach the chain hoist to the engine (see step
35 on page 5-6).-2 Disconnectthe suspension lower arm balljoints (see step 3 on page 18-19).-3 Remove the rear mounl mounting bolts (see
step 39 on page 5-7).-4 Remove the front mount mounting bolt (see
step 40 on page 5-7).-5 Use a marker to make alignment marks on the
reference lines that align with the centers of
the rear subframe mounting bolts. Remove the
front subframe (see step 43 on page 5-8).
Remove the bolts/nuts securing the oil pan.
Drive an oil pan seal cutter between the oil pan and
cylinder block.
5. Cut the oil panseal bystrikingthesideofthecutter
to slide the cutter along the oil pan.

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'.
