Check the crankshaft journals and pins for damage, uneven wear, and cracks. Also check oil holes for clogging. Correct or replace any defective part.
Inspect the crankshaft journal for taper and out - of - round.
Standard value
Crankshaft journal O.D : 50 mm (1.9685 in.)
Crankshaft pin O.D : 45 mm (1.7717 in.)
Crankshaft journal, pin out-of-roundness and taper :
0.005 mm (0.0002 in.) or less
Visually inspect each bearing for peeling, melting, seizure, and improper contact. Replace the defective bearings.
Measure the diameter of the crankshaft journal and pin.
Measure the diameter of the crankshaft bore and connecting rod bore.
Measure the thickness of the crankshaft bearing and connecting rod bearing.
Measure the clearance by the value that subtract the diameter of journal and pin and the thickness of bearing from the diameter of bore.
Connecting rod bearing oil clearance :
0.018 ~ 0.036 mm (0.0007 ~ 0.0014 in.)
Crankshaft main bearing oil clearance
NO. 1,2,4,5 : 0.022 ~ 0.040 mm (0.0009 ~ 0.0018 in.)
NO.3 : 0.028 ~ 0.046 mm (0.0011 ~ 0.0018 in.)
Check front and rear oil seals for damage or wear. Replace any seal that is defective.
Remove the sensor wheel.
Check the sensor wheel for damage, cracks and wear, and replace if necessary.
Check the clearance between the sensor wheel and the crank position sensor with a depth gage.
Standard value
Clearance between sensor wheel and crank position sensor : 0.5 ~ 1.1 mm (0.020 ~ 0.043 in.)
Measure the depth of the top of sensor wheel tooth and the cylinder block mounting block.
Measure the difference between sensor length and depth.
Sensor length is the distance between the end of the sensor and the inner point of the contacting face.
Check the clutch disc contacting surface of the flywheel for damage and wear. Replace the flywheel if excessively damaged or worn.
Check the clutch disc contacting surface of the flywheel for runout.
Standard value
Flywheel run - out : 0.1 mm (0.0039 in.)
Check the ring gear for damage, cracks, and wear, and replace if necessary.
