Crankshaft: Testing and Inspection
VISUAL INSPECTION
Check the crankshaft journals and pins for damage, uneven wear and cracks.Also check oil holes for clogging.Correct or replace any defective
part.
Visually inspect each Main Bearings and Connecting Rod bearing for peeling, melt, seizure and improper contact.Replace the defective bearings.
DIAMETER AND TAPER INSPECTION
Using a suitable micrometer, inspect out-of-roundness and taper of crankshaft main bearing journal and connecting rod pin.
Standard value:
Crankshaft journal O.D 50 mm (1.9685 inch).
Crankshaft pin O.D 45 mm (1.7717 inch).
Crankshaft journal, pin out-of-roundness and taper 0.01 mm (0.0004 inch) or less.
JOURNAL OIL CLEARANCE MEASUREMENT
Micrometer Method
Using suitable external and internal micrometers, measure outside diameter of the crankshaft journal and the crank pin and inside diameter of the
bearing.
-
The clearance measurement is the different between the measured outside and inside diameters.
Plastigauge Method
1. Remove oil, grease and any other dirt from bearings and journals.
2. Cut plastigauge to the same length as the width of the bearing and place it in parallel with the journal, off oil holes.
3. Install the crankshaft, bearings, and caps.
4. Tighten them to 55-60 Nm (550-600 kg. cm., 40-44 ft. lbs.).
-
During this operation, do not turn the crankshaft.
5. Remove the caps.
6. Measure the width of the plastigauge at the widest point using the scale printed on the gauge package.
-
If the clearance exceeds the repair limit, replace the bearing.
-
Should the standard clearance not be obtained even after bearing replacement, the journal should be ground to a recommended undersize,
and a bearing of the same size should be installed.
