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

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.

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.

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)
