Installation
CAUTION
!
• Use new bearing cap No.1 bolts. If they are
reused, check thread diameters of bearing
cap No.1 bolt for deformation according to
previous mentioned “Bearing Cap Bolt”
under “Main Bearings Inspection”, check
and replace them with new ones if thread
diameter exceeds limit.
• All parts to be installed 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 specified 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 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.
3) Install thrust bearings (1) to cylinder block between
No.2 and No.3 cylinders. Face oil groove (2) sides to
crank webs.
4) Confirm that dowel pins (3) are installed to intake
side of each journal.
5) Install crankshaft to cylinder block.
6) 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 new bearing cap No.1
bolts (1) – (10) and bearing cap No.2 bolts (11) –
(20), tighten them gradually as follows.
a) Tighten bolts (1) – (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
°
