2) Tighten main bearing cap No.1 bolts (a) and main bearing cap No.2 bolts (b ) 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 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” through “18”) to 25 N ⋅m (2.5
kgf-m, 18.0 lb-ft) according to numerical order in
figure.
Tightening torque
Main bearing cap No.1 bolt (a): 30 N ⋅m (3.0

and then retighten by turning through 60 °
Main bearing cap No.2 bolt (b): 25 N·m (2.5
kgf-m, 18.0 lb-ft) 3) Use a dial gauge to read displacement in axial
(thrust) direction of crankshaft.
If its limit is exceeded, replace thrust bearing with
new standard one or oversize one to obtain standard
thrust play.
Crankshaft thrust play
Standard: 0.11 – 0.31 mm (0.0043 – 0.0122 in.)
Limit: 0.35 mm (0.0138 in.)
NOTE
After checking the thrust play, make sure that
thread deformation of each bearing cap No.1
bolt referring to “Main Bearing Cap No.1
Bolt” in “Main Bear ings Inspection”.

Out-of-Round and Taper (Uneven Wear) of Journals
An unevenly worn crankshaft journal shows up as a
difference in diameter at a cross section or along its
length (or both). This difference, if any, is determined by
taking micrometer readings. If any one of journals is
badly damaged or if amount of uneven wear in the sense
exceeds its limit, regrind or replace crankshaft.
