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.
a) Tighten bolts (1) – (10) to 30 N·m (3.0 kg-m, 22.0 lb-ft)
according to numerical order as shown by using a 12 cor-
ner socket wrenches.
b) In the same manner as in Step a), tighten them to 50 N·m
(5.0 kg-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 kg-m, 18.0 lb-ft)
according to numerical order as shown.
Tightening torque
Main bearing No.1 bolts (1) – (10)
: 30 N·m (3.0 kg-m, 22.0 lb-ft), 50 N·m (5.0 kg-m, 36.5 lb-ft)
and then retighten by turning through 60°
Main bearing No.2 bolts (11) – (20)
: 25 N·m (2.5 kg-m, 18.0 lb-ft)
CAUTION:
After tightening cap bolts, check to be sure that crank-
shaft rotates smoothly when turning it by 12 N·m (1.2 kg-
m, 9.0 lb-ft) torque or below.
7) If necessary, press-fit rear oil seal (1) to oil seal housing (2)
by using special tool as shown in the figure.
