Sonata V6-2.7L (2004)
2. Inspect the crankshaft journal and pin for out-of-round and taper.
Standard value
Crankshaft journal O.D: 61.982 - 62.000 mm (2.4402 - 2.4409 inch)
Crankshaft pin O.D: 47.982 - 48.000 mm (1.8890 - 1.8898 inch)
MAIN BEARINGS AND CONNECTING ROD BEARINGS
Visually inspect each bearing for peeling, melting, seizure and improper contact. Replace any defective bearings.
MEASURING OIL CLEARANCE
Check for oil clearance by measuring the outside diameter of the crankshaft journal and the inside diameter of the bearing. The clearance can be
obtained by calculating the difference between the measured outside diameters.
Standard value
Oil clearance
Crankshaft main bearing: 0.004 - 0.022 mm (0.00015 - 0.00087 inch)
Connecting rod bearing: 0.018 - 0.036 mm (0.00071 - 0.00141 inch)
Limit: 0.1 mm (0.004 inch)
PLASTIC GAUGE METHOD
Plastic gauge may be used to measure the clearance.
1. Remove oil, grease and any other dirt from the bearings and journals.
2. Cut the plastic gauge the same length as the width of the bearing and place it in parallel with the journal, avoiding the 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 plastic gauge at the widest part by using the scale printed on the gauge package.
If the clearance exceeds the service 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.
If the standard clearance can not be obtained even after replacing the bearing, the journal and pin should be ground to the undersize and a bearing
of the corresponding size should be installed.
OIL SEAL
Check the front and rear oil seals for damage or worn surfaces. Replace any seat that is defective.
