Crankshaft Main Bearing

Crankshaft bearing cap bolts





Tighten the 10 bearing cap bolts in the sequence shown in the illustration
1st 20 Nm (204 kgf-cm, 15 ft-lbf)
2nd 40 Nm (408 kgf-cm, 30 ft-lbf)
Final 90° in the order shown in step 1

If a crankshaft bearing cap bolt does not meet the specified torque, replace it.

Crankshaft bearing





Dimension A - B or B - A 0 to 0.7 mm (0 to 0.0276 in.)

HINT
If replacing a bearing, select a new one with the same number. If the number of the bearing cannot be determined, calculate the correct bearing number by adding together the numbers imprinted on the cylinder block and crankshaft. Then select a new bearing with the calculated number. There are 4 sizes of standard bearings, marked "1", "2", "3" and "4" accordingly.








EXAMPLE
Cylinder block (A) "3" + Crankshaft (B) "4" = Total "7"
Select the bearing marked "3"
