Setup and Installation
Replacing drive belts in a cassette deck requires careful handling and some technical proficiency. If you are unsure about any step, it is recommended to seek assistance from a qualified technician.
- Preparation: Disconnect the cassette deck from all power sources and audio connections. Place the unit on a clean, stable, and well-lit work surface.
- Accessing the Mechanism: Carefully remove the outer casing of the Aiwa AD-WX 717 cassette deck to gain access to the internal tape transport mechanism. Refer to your cassette deck's service manual for specific instructions on casing removal.
- Identifying Old Belts: Locate the existing drive belts. These may be worn, stretched, or disintegrated. Note their routing paths around the motor pulley, flywheels, and other capstans/pulleys.
- Removing Old Belts: Gently remove the old belts. If they have disintegrated, carefully clean any residue from the pulleys and surfaces using isopropyl alcohol and a cotton swab.
- Installing New Belts: Carefully route the new Thakker flat belts according to the original path. Ensure the belts are seated correctly on all pulleys and flywheels without any twists or kinks. The belts should have appropriate tension, neither too loose nor too tight.
- Testing: Before reassembling the casing, temporarily connect the power and test the tape transport functions (Play, Fast Forward, Rewind) to ensure the new belts are functioning correctly and smoothly.
- Reassembly: Once confirmed, carefully reassemble the cassette deck casing, ensuring all screws are tightened appropriately and no wires are pinched.
Operating Considerations
After installation, the cassette deck should operate with improved stability and reduced wow and flutter. No specific operational changes are required for the belts themselves, as they are internal components.
- Ensure the cassette deck is placed on a level surface.
- Avoid exposing the unit to extreme temperatures or humidity, which can affect belt longevity.
Maintenance
The Thakker AD-WX 717 belt kit is designed for durability. Regular maintenance of the belts themselves is generally not required beyond proper installation. However, general maintenance of the cassette deck is recommended:
- Cleaning: Periodically clean the tape heads, capstan, and pinch roller with a specialized head cleaner and cotton swabs to ensure optimal sound quality and prevent tape damage.
- Dust Removal: Keep the cassette deck free from dust by using a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Storage: When not in use for extended periods, store the cassette deck in a cool, dry place away from direct sunlight.
Troubleshooting
If you encounter issues after installing the new belts, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tape speed inconsistent (wow/flutter) | Belts not seated correctly, incorrect belt tension, or other mechanical issues. | Re-check belt routing and tension. Ensure pulleys are clean. Inspect other moving parts for lubrication needs. |
| Tape transport not functioning (Play, FF, RW) | Belts slipped off, broken, or motor issue. | Verify belts are on pulleys. Check motor operation. |
| Squeaking noise during operation | Friction from dry bearings or misaligned parts. | Lubricate moving parts as per the cassette deck's service manual. Ensure belts are not rubbing against other components. |
For complex issues, consult a professional audio equipment repair technician.
