CRANKSHAFT





Uniformly tighten the 10 crankshaft bearing cap bolts in several passes in the sequence shown in the illustration.

Torque 27 Nm (275 kgf-cm, 20 ft-lbf)





Mark the front of the crankshaft bearing cap bolts with paint.
Tighten the crankshaft bearing cap bolts an additional 90° as shown in the illustration.
Check that the painted marks are now at a 90° angle to the front.
Check that the crankshaft turns smoothly














There are 5 sizes of standard bearings. For No. 1 and No. 5 position bearings, use bearings marked 3, 4, 5, 6 and 7. For other position bearings, use bearings marked 1, 2, 3, 4 and 5.





A = Cylinder block number mark
B = Crankshaft number mark

EXAMPLE:
No. 1 and No. 5 journal
Cylinder block "7" + Crankshaft "6" = Total number 13 (Use upper bearing "4" and lower bearing "5")

Other journal
Cylinder block "7" + Crankshaft "6" = Total number 13 (Use upper bearing "2" and lower bearing "3")

(Cylinder block journal diameter - crankshaft journal diameter - 5) X 1000 = A + B
