4) Tighten bearing cap No.1 bolts (1) – (10) and No.2
bolts (11) – (20) gradually as follows.
a) Tighten bolts (1) – (10) to 30 N
⋅
m (3.0 kgf-m,
22.0 lb-ft) according to numerical order in the
figure.
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 in the
figure.
Tightening torque
Crankshaft bearing cap No.1 bolt (1) – (10):
Tighten 30 N
⋅
m (3.0 kgf-m, 22.0 lb-ft), 50 N
⋅
m
(5.0 kgf-m, 36.5 lb-ft) and 60
°
by the specified
procedure
Crankshaft bearing cap No.2 bolt (11) – (20):
Tighten 25 N
⋅
m (2.5 kgf-m, 18.0 lb-ft) by the
specified procedure
NOTE
Do not rotate crankshaft while gauging
plastic is installed.
5) Remove bearing caps, and measure gauging plastic
(2) width at its widest point using scale (1) on
gauging plastic envelop. If clearance exceeds its
limit, replace bearing. Always replace both upper
and lower inserts as a unit.
A new standard bearing may produce proper
clearance. If not, it will be necessary to regrind
crankshaft journal for use of 0.25 mm (0.0098 in.)
undersize bearing.
After selecting new bearing, recheck clearance.
Main bearing clearance
Standard: 0.021 – 0.041 mm (0.0008 – 0.0016 in.)
Limit: 0.054 mm (0.0021 in.)
NOTE
After checking the bearing clearance, make
sure that thread deformation of each bearing
cap No.1 bolt according to previous
mentioned Step 4) once again.
