Install lower cylinder block bolts in numerical order as shown in the figure as follows:
Apply new engine oil to threads and seat surfaces of lower cylinder block bolts.





Tighten lower cylinder block bolts (No. 17 to 26) in numerical order as shown in the figure.
<---: Engine front
Torque 25.0 Nm (2.6 kg-m, 18 ft-lb)
Repeat step b.





Tighten lower cylinder block bolt (No. 1 to 16) in numerical order as shown in the figure.
<---: Engine front
Torque 35.3 Nm (3.6 kg-m, 26 ft-lb)
Turn lower cylinder block bolt (No. 1 to 16) 90° clockwise (angle tightening).

CAUTION:





Use the angle wrench [SST: KV10112100 (BT8653-A)] (A) to check tightening angle. Never make judgment by visual inspection.

After installing lower cylinder block bolts, check that crankshaft can be rotated smoothly by hand.
Check the crankshaft end play.

LOWER CYLINDER BLOCK BOLT OUTER DIAMETER





Measure the outer diameters (c), (d) at two positions as shown in the figure.
a 20 mm (0.79 in)
b 30 mm (1.18 in)
e 10 mm (0.39 in)
If reduction appears in (a) range, regard it (c).
Limit [(d) - (c)] 0.11 mm (0.0043 in)
If it exceeds the limit (large difference in dimensions), replace lower cylinder block bolt with new one.
