Crankshaft Main Bearing

CRANKSHAFT BEARING CAP BOLTS




Using several steps, uniformly install and tighten the 10 bearing cap bolts in the sequence shown in the illustration.
Torque: 40 Nm (408 kgf-cm, 30 ft-lbf)





Mark the front of the bearing cap bolts with paint.
Retighten the 8 bearing cap bolts by 90° in the same sequence.
Check that the paint marks are now at a 90° angle to the front.

STIFFENING CRANKCASE





Temporarily install the crankcase with the 11 bolts.

Bolt length: 112 mm (4.41 in.) for A of 12 mm head
35 mm (1.38 in.) for B of 12 mm head

Uniformly tighten the bolts.
Torque: 32.5 Nm (331 kgf-cm, 24 ft-lbf)





Confirm that the timing marks of the balance shafts are aligned when the key groove is placed at the 6 o'clock position, as shown in the illustration.
