Elantra L4-1595cc 1.6L DOHC (1993)
Crankshaft
1. Check the crankshaft journals and pins for damage, uneven wear and cracks. Also check oil holes for clogging. Correct or replace any defective
pert.
2. Inspect out-of-roundness and taper of crankshaft journal and pin.
Standard value
Crankshaft journal O.D 57 mm (2.24 in.)
Crankshaft pin O.D 45 mm (1.77 in.)
Main Bearing and Connecting Rod Bearings
Visually inspect each bearing for peeling, melt, seizure and improper contact. Replace the defective bearings.
Oil Clearance Measurement
To check the oil dearance, measure the outside diameter of the crankshaft journal and the crank pin and the inside diameter of the bearing. The
clearance can be obtained by calculating the difference between the measured outside and inside diameter.
Standard value
Oil clearance
Crankshaft main bearing 0.02-0.05 mm (0.0008-0.0020 in.)
Connecting rod bearing 0.02-0.05 mm (0.0008-0.0020 in.)
Limit 0.1 mm (0.004 in.)
Plastigauge Method
Plastigauge may be used to measure the clearance.
1. Remove oil and 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 and tighten them to the specified torques. During this operation, do not turn the crankshaft. Remove the
caps. Measure the width of the plastigauge at the widest part by using a scale printed on the gauge package. If the dearance exceeds the repair
limit, the bearing should be replaced or an undersize bearing should be used.
When installing a new crankshaft, be sure to use standard size bearings.
Should the standard dearance not be obtained even after bearing replacement, the journal and pin should be ground to undersize and a bearing of
the same size should be installed.
