Main Bearing Cap





Install each main bearing cap bolt as follows:
Apply new engine oil to threads and seating surface of main bearing cap bolts, and tighten all bolts temporarily.
Tighten main bearing cap bolt (M12) in order of 1 to 10.

Tighten main bearing cap sub bolt (M9) in order of 11 to 20.
Torque 29.4 Nm (3.0 kg-m, 22 ft. lbs.)





Tighten main bearing cap bolt (M12) to 40° clockwise in order of 1 to 10. (Angle tightening)

CAUTION: Use angle wrench (SST) to check tightening angle in step d and e. Do not make judgment by visual inspection.

Tighten main bearing cap sub bolt (M9) to 30° clockwise in order of 11 to 20. (Angle tightening)
Tighten side bolt (M10) in order of 21 to 30.

MAIN BEARING HOUSING INNER DIAMETER





^ Install main bearing caps and main bearing without installing main bearings, and tighten main bearing cap bolts to the specified torque.
^ Measure the inner diameter of main bearing housing with bore gauge.
Standard 68.944 - 68.968 mm (2.7143 - 2.7153 inch)
^ If out of the standard, replace cylinder block and main bearing caps as assembly.

NOTE: Cylinder block cannot be replaced as a single part, because it is machined together with main bearing caps.
