1D-54 Engine Mechanical: For M16A Engine with VVT
Installation
NOTE
• 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 main bearing cap No.1
bolts ((1) – (10)) and main bearing cap No.2 bolts
((11) – (20)), tighten them gradually as follows.
NOTE
If main bearing cap No.1 bolt is reused, make
sure to check main bearing cap No.1 bolt for
deformation referring to "Main Bearing Cap
No.1 Bolt" under "Main Bearings Inspection:
For M16A Engine with VVT".
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°.
d) Tighten bolts ((11) – (20)) 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 ((1) – (10)): 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 ((11) – (20)): 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)
