1. Using a vernier caliper, measure the tension portion diameter of the bolt.
  
  Standard diameter
  
  7.2 to 7.3 mm (0.283 to 0.287 in.)
  
  Minimum diameter
  
  7.0 mm (0.276 in.)
  
  If the diameter is less than the minimum, replace the bolt.

INSPECT CRANKSHAFT

Inspect for circle runout.
1. Place the crankshaft on V-blocks.
2. Using a dial indicator, measure the circle runout at the center journal.
  
  Maximum circle runout
  
  0.03 mm (0.0012 in.)
  
  If the circle runout is greater than the maximum, replace the crankshaft.

Inspect the main journals.

Using a micrometer, measure the diameter of each main journal.

Standard journal diameter

Journal	Diameter
No. 3	59.981 to 59.994 mm (2.3615 to 2.3620 in.)
Except No. 3	59.987 to 60.000 mm (2.3229 to 2.3622 in.)

If the diameter is not as specified, check the oil clearance. If necessary, replace the crankshaft.

Check each main journal for taper and out-of-round as shown in the illustration.

Maximum taper and out-of-round

0.005 mm (0.0002 in.)

If the taper and out-of-round is greater than the maximum, replace the crankshaft.

Inspect the crank pin.
1. Using a micrometer, measure the diameter of each crank pin.
  
  Standard diameter
  
  52.989 to 53.002 mm (2.0862 to 2.0867 in.)
  
  If the diameter is not as specified, check the oil clearance (see "INSPECT CONNECTING ROD OIL CLEARANCE" procedure). If necessary, replace the crankshaft.
2. Check each crank pin for taper and out-of-round as shown in the illustration.
  
  Maximum taper and out-of-round
  
  0.003 mm (0.0001 in.)
  
  If the taper and out-of-round is greater than the maximum, replace the crankshaft.

INSPECT CRANKSHAFT BEARING CAP SET BOLT
1. Using a vernier caliper, measure the minimum diameter of the elongated thread at the measuring point.
  
  Standard outside diameter
  
  10.76 to 10.97 mm (0.4236 to 0.4319 in.)
  
  Minimum outside diameter
  
  10.66 mm (0.4197 in.)
  
  If the diameter is less than the minimum, replace the crankshaft bearing cap bolt.
