Repair and Diagnosis: Service and Repair

REMOVAL OF PARTS
First find the cause of the problem and then determine removal or disassembly is required before starting the job.

DISASSEMBLY
If the disassembly procedure is complex and requires many parts to be disassembled, all parts should be disassembled in a way that will not affect their performance or external appearance.




1. Inspection of parts
Each part, when removed, should be carefully inspected for malfunction, deformation, damage, and other problems.




2. Arrangement of parts
All disassembled parts should be carefully arranged for effective reassembly.

Be sure to separate and correctly identify the parts to be replaced from those that will be used again.




3. Cleaning parts for reuse
All parts to be used again should be carefully and thoroughly cleaned by the appropriate method.







PARTS
When replacing parts, use HYUNDAI genuine parts.




REPLACEMENT
Standard values, such as torques and certain adjustments, must be strictly observed in the reassembly of all parts.
If removed, the following parts should be always replaced with new ones.
1. Oil seals
2. Gaskets
3. O-rings
4. Lock washers
5. Cotter pins (split pins)
6. Plastic nuts




Depending on their location.
7. Sealant should be applied to gaskets.
8. Oil should be applied to the moving components of parts.
9. Specified oil or grease should be applied to the prescribed locations (oil seals, etc.) before assembly.

ADJUSTMENT
Use gauges and testers to adjust correctly the parts to standard values correctly.




ELECTRICAL SYSTEM
1. Be sure to disconnect the battery cable from the negative (-) terminal of the battery.
2. Never pull on the wires when disconnecting connectors.
3. Locking connectors will click when the connector is secure.
4. Handle sensors and relays carefully. Be careful not to drop them or hit them against other parts.
