Main Bearing Cap
Reinstall the bearings and caps, then torque the bearing cap bolts to 74 Nm (7.5 kgf-m, 54 ft. lbs.), and the bearing cap side bolts to 49 Nm (5.0 kgf-m, 36 ft. lbs.), in the proper sequence.
Tighten the bearing cap bolts, and then the bearing cap side bolts to the specified torque in the sequence as shown. Repeat the torque sequence again to measure the bolts are properly torqued.

Crankshaft Bore Code Location
Letters or bars have been stamped on the end of the block as a code for the size of each of the four main journal bores.
Use them, and the numbers stamped on the crankshaft (codes for main journal size), to choose the correct bearings. If the codes are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.
