Plastic Gauge Method; Oil Seal; Main Bearing - Hyundai Tiburon 2003 Workshop Manual

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 plasticgauge at the widest part by
usingthe 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.
Drive Plate (A/T)
Replace distorted, damaged, or cracked drive plates.
FLYWHEEL (M/T)
See EM section.
