• Select proper new bearing shells with references to table.
• Coat the new bearing shells with oil and insert into the crankcase and into the crankshaft bearing caps.

Note: Do not mix up upper and lower crank shaft bearing shells

• Install the bearing caps according to marking and tighten the 12-sided stretch bolts. (Fig 5)
Installation Notice

Tightening Torque 55 N·m (41 lb-ft) + 90°
No. 1 is vibration damper side. (Fig 2)
• Measure crank shaft bearing diameters (E) using the dial gauge 00 and extension. (Fig 6)

Fig 5 Fig 6

• Measure at 3 points (A, B and C) and if the average value of B and C is less than A’s value, the average value
of B and C is the mean value and if more than A’s value, A’s value is the mean value.(Fig 7)
• Measure crankshaft bearing journal diameter (F). (Fig 8)

Notice: When measured in A and B, the runout should not exceed 0.010 mm.

• Measure radial clearance of crankshaft bearing (G).

Clearance ‘G’ 0.027-0.051 mm

Note: Compare final radial clearance figure of crankshaft bearing to the service manual.
