Tightening Torques and Sequences

Main Bearing Cap Torque and Sequence

Tighten the bearing cap bolts in sequence to 25 N-m (2.5 kgf-m, 18 lbf-ft).






Tighten the bearing cap bolts an additional 40 °.

Rod Bearing Selection

Connecting Rod Big End Bore Code Locations

Each rod falls into one of four tolerance ranges (from 0 to 0.024 mm (0.0009 in.), in 0.006 mm (0.0002 in.) increments) depending on the size of its big end bore. It's then stamped with a number or bar (1, 2, 3, or 4) indicating the range. You may find any combination of 1, 2, 3, or 4 in any engine.

If you can not read the codes, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.










Connecting Rod Journal Code Location

The connecting rod journal codes are stamped on the crankshaft.






Use the big end bore codes and rod journal codes to select appropriate replacement bearings from the following table.

NOTE: Color code is on the edge of the bearing.





Crankshaft Pulley Torque

Tighten the crankshaft pulley bolt. Do not use an impact wrench.

Hold the pulley with the handle (A) and crankshaft pulley holder (B), then tighten the bolt to 37 N-m (3.8 kgf-m, 27 lbf-ft) with a torque wrench and a 19 mm socket (C). If the pulley bolt or crankshaft are new, tighten the bolt to 177 N-m (18.0 kgf-m, 130 lbf-ft), then remove the bolt and tighten it to 37 N-m (3.8 kgf-m, 27 lbf-ft).

Mark the embossed mark (D) on the bolt flange and the crankshaft pulley (E) as shown, then tighten the bolt an additional 90 ° (The mark on the bolt head should line up with the next embossed mark (F) on the bolt flange).
