Tires InspectionS7RS0B0206020
1) Check tires for uneven or excessive wear, or damage. If defective, replace.
Refer to “Irregular and/or Premature Wear
Description in Section 2D” and “Wear Indicators
Description in Section 2D” for details.
2) Check inflating pressure of each tire and adjust pressure to specification as necessary.
NOTE
• Tire inflation pressure should be checked when tires are cool.
• Specified tire inflation pressure should be found on tire placard or in owner’s manual
which came with the vehicle.

3) Rotate tires. For details, refer to “Tire Rotation in Section 2D”.
Wheel Discs InspectionS7RS0B0206021
Inspect each wheel disc for de nts, distortion and cracks.
A disc in badly damaged condition must be replaced.
Wheel Bearing InspectionS7RS0B0206022
1) Check front wheel bearing for wear, damage, abnormal noise or rattles. For details, refer to “Front
Wheel Hub, Disc, Nut and Bearing Check in Section
2B”.
2) Check rear wheel bearing for wear, damage, abnormal noise or rattles. For details, refer to“Rear
Wheel Disc, bolt and Bearing Inspection in Section
2C”.
Suspension System InspectionS7RS0B0206023
• Inspect front struts and rear shock absorbers for evidence of oil leakage, dents or any other damage on
sleeves; and inspect anchor ends for deterioration.
Replace defective parts, if any.
• Check front and rear suspension systems for damaged, loose or missing parts; also for parts
showing signs of wear or lack of lubrication.
Repair or replace defective parts, if any.
• Check front suspension arm ball joint stud dust seals for leakage, detachment, tear or any other damage.
Replace defective boot, if any.

Installation
NOTE
• Use new bearing cap No.1 bolts. They are deformed once they are used because they
are plastic deformation tightening bolts.
• All parts to be insta lled must be perfectly
clean.
• Be sure to oil crankshaft journals, journal bearings, thrust bearings, crankpins,
connecting rod bearings, pistons, piston
rings and cylinder bores.
• Journal bearings, bearing caps, connecting rods, rod bearings, rod bearing
caps, pistons and piston rings are in
combination sets. Do not disturb such
combination and make sure that each part
goes back to where it came from, when
installing.

1) Install sensor plate (1) to crankshaft (2) and tighten bolts to spec ified torque.
NOTE
When installing sensor plate, align spring pin
(3) on crankshaft and hole of sensor plate.

Tightening torque
Sensor plate bolt (a): 11 N·m (1.1 kgf-m, 8.0 lb-ft) 2) Install piston cooling valves and nozzles, if removed.
NOTE
Install piston cooling valve while matching
piston cooling nozzle (1) to positioning (3) of
cylinder block when installed piston cooling
valve (2).

Tightening torque
Piston cooling valve (a): 11 N·m (1.1 kgf-m, 8.0
lb-ft)
3) Install main bearings to cylinder block. Upper half of bearing (1), has an oil groove (2).
Install it to cylinder block (3), and the other half
without oil groove to bearing cap.
Make sure that two halves are painted in the same
color.
4) Confirm that dowel pins (3 ) are installed to intake
side of each journal.

5) Install crankshaft to cylinder block.
6) Install thrust bearings (1) to cylinder block between No.2 and No.3 cylinders. Face oil groove (2) sides to
crank webs.
7) Install bearing cap to cylinder block, making sure to point arrow mark (on each cap) to crankshaft pulley
side. Fit them sequentially in ascending order, 1, 2,
3, 4 and 5, starting from pulley side.
After applying engine oil to main bearing cap No.1
bolts (a) and main bearing cap No.2 bolts (b), tighten
them gradually as follows.
a) Tighten bolts (“1” through “10”) to 30 N ⋅m (3.0
kgf-m, 22.0 lb-ft) according to numerical order as
shown by using a 12 corner socket wrenches.
b) In the same manner as in Step a), tighten them to 50 N ⋅m (5.0 kgf-m, 36.5 lb-ft).
c) In the same manner as in Step a), retighten them to 60 °.
d) Tighten bolts (“11” through “18”) to 25 N ⋅m (2.5
kgf-m, 18.0 lb-ft) according to numerical order as
shown.
Tightening torque
Main bearing cap No.1 bolt (a): 30 N ⋅m (3.0
kgf-m, 22.0 lb-ft), 50 N ⋅m (5.0 kgf-m, 36.5 lb-ft)
and then retighten by turning through 60 °
Main bearing cap No.2 bolt (b): 25 N·m (2.5
kgf-m, 18.0 lb-ft)
CAUTION!
After tightening cap bolts, check to be sure
that crankshaft rotates smoothly when
turning it by 12 N ⋅m (1.2 kgf-m, 9.0 lb-ft)
torque or below.

8) If necessary, press-fit rear oil seal (1) to oil seal housing (2) by using special tool as shown in figure.

Main bearing cap No.2 bolt (b): 25 N·m (2.5
kgf-m, 18.0 lb-ft) 3) Use a dial gauge to read displacement in axial
(thrust) direction of crankshaft.
If its limit is exceeded, replace thrust bearing with
new standard one or oversize one to obtain standard
thrust play.
Crankshaft thrust play
Standard: 0.11 – 0.31 mm (0.0043 – 0.0122 in.)
Limit: 0.35 mm (0.0138 in.)
NOTE
After checking the thrust play, make sure that
thread deformation of each bearing cap No.1
bolt referring to “Main Bearing Cap No.1
Bolt” in “Main Bear ings Inspection”.

Out-of-Round and Taper (Uneven Wear) of Journals
An unevenly worn crankshaft journal shows up as a
difference in diameter at a cross section or along its
length (or both). This difference, if any, is determined by
taking micrometer readings. If any one of journals is
badly damaged or if amount of uneven wear in the sense
exceeds its limit, regrind or replace crankshaft.
