>>D<< CONNECTING ROD BEARING INSTALLATION
1. Measure the crankshaft pin diameter and confirm its

classification from the following table. In the case of a
crankshaft supplied as a service part, identification colors/
marks of its pins are painted /stamped at the positions
shown in the illustration.

2. If the crankshaft pin outside diameter ID color is yellow, for

example, select a bearing whose ID mark is 1 or ID color is
yellow.
If there is no ID color paint on the crankshaft, measure the
pin outside diameter and select a bearing appropriate for the
measured value.

3. Install the selected bearing in the big end and in the cap of

the connecting rod.

>>E<< PISTON AND CONNECTING ROD INSTALLATION
1. Apply engine oil on the circumference of the piston, piston

rings, and oil ring.

2. Arrange the piston ring and oil ring gaps (side rail and

spacer) as shown in the illustration.

3. Rotate the crankshaft so that crank pin is on the center of

the cylinder bore.

4. Use suitable thread protectors on the connecting rod bolts

before inserting the piston and connecting rod assembly into
the cylinder block.
Care must be taken not to nick the crank pin.

5. Insert the piston and connecting rod assembly into the

cylinder with front mark on the piston crown pointing to the
timing belt side.

6. Using a suitable piston ring compressor tool, install the

piston and connecting rod assembly into the cylinder block.

>>F<< CONNECTING ROD CAP INSTALLATION
1. Verifying the mark made during disassembly, install the

bearing cap to the connecting rod. If the connecting rod is
new with no index mark, make sure that the bearing locking
notches are on the same side as shown.

2. Make sure that the connecting rod big end side clearance

meets the specification.

Limit: 0.4 mm (0.015 inch)

>>G<< CONNECTING ROD CAP NUT TIGHTENING
1. The connecting rod bolts should be examined before reuse.

If the bolt threads are damaged, the bolt should be replaced.
Hand-thread the nut to the full length of the bolt threads. If
the nut does not run down smoothly, the bolt should be
replaced.

2. Before installation of each nut, apply engine oil to the

threaded portion and bearing surface of the nut.

3. Loosely tighten each nut to the bolt.

4. Then tighten the nuts alternately to a torque of 20 N

⋅

m (14 ft-

lb) to install the cap properly.

5. Make a paint mark on the head of each nut.

6. Make a paint mark on the bolt end at the position 90 degree

angle to 94 degree angle from the paint mark made on the
nut in the direction of tightening the nut.

CAUTION

•

If the nut is turned less than 90 degree angle, proper
fastening performance may not be achieved. Be careful
to tighten the nut exactly 90 degree angle.

•

If the nut is overtightened (exceeding 94 degree angle),
loosen the nut completely and then retighten it by
repeating the tightening procedure from step 3.

7. Turn the nut further 90 degree angle to 94 degree angle and

make sure that the paint marks on the nut and bolt are
aligned.

INSTALLATION SERVICE POINTS

>>A<< CRANKSHAFT THRUST BEARING INSTALLATION
1. Install the two thrust bearings in the number 3 bearing bore

in the cylinder block. For easier installation, apply engine oil
to the bearings; this will help hold them in position.

2. The thrust bearings must be installed with their groove side

toward the crankshaft web.

>>B<< CRANKSHAFT BEARING INSTALLATION
When bearing replacement is required, select and install the
correct bearing by the following procedure.
1. Measure the crankshaft journal diameter and confirm its

classification from the following table. In the case of a
crankshaft supplied as a servise part, identification colours/
marks of its journals are painted/stamped at the positions
shown in the illustration.
