Tightening Torque and Sequence

Main Bearing Cap





Tighten lower cylinder block bolts in the numerical order as shown and according to the following steps:
Apply new engine oil to threads and seat surfaces of the bolts.
Tighten bolts No. 11 - 22 only in the order as shown, to specification below.
Step 1, bolts 11 - 22 only 25.1 Nm (2.6 kg-m, 19 ft-lb)
Tighten bolts No. 1 - 10 only in the order as shown, to specification below.
Step 2, bolts 1 - 10 only 39.2 Nm (4.0 kg-m, 29 ft-lb)

CAUTION:
Check tightening angle. Do not make judgment by visual inspection.

Tighten bolts No. 1 - 10 only in the order as shown, to specification below.
Tool number KV10112100 (BT-8653-A)
Step 3, bolts 1 - 10 only 60° degrees rotation
Wipe off completely any protruding Silicone RTV Sealant on rear oil seal installation surface and the exterior of engine.
Check crankshaft side clearance. Refer to EM-82, "Inspection After Disassembly". Inspection After Disassembly
After installing the bolts, make sure that the crankshaft can be rotated smoothly by hand.

OUTER DIAMETER OF LOWER CYLINDER BLOCK BOLT
Perform only with M10 (0.39 in) bolts.
Measure outer diameters (d1, d2) at two positions as shown.
Measure d2 at a point within area A as shown.





When the value of d1 - d2 exceeds the limit (a large difference in dimensions), replace the bolt with a new one.
Limit 0.13 mm (0.0051 in)
