3. Installation Guide
Important: Disconnect the cassette deck from the power supply before beginning any installation or maintenance. Proceed with caution and refer to your Aiwa AD-WX 616 service manual if available for specific disassembly instructions.
- Preparation: Place the cassette deck on a clean, stable, and well-lit surface. Gather necessary tools such as small screwdrivers (Phillips and flathead), tweezers, and a clean cloth.
- Accessing the Drive Mechanism: Carefully remove the outer casing of the Aiwa AD-WX 616 cassette deck. This typically involves unscrewing screws on the back, sides, and bottom panels. Note the location of each screw for reassembly.
- Locating Old Belts: Once the internal components are accessible, identify the existing drive belts. These are usually located around the motor pulley, flywheel, and other drive mechanisms. Old belts may be stretched, cracked, or melted.
- Removing Old Belts: Gently remove the old belts. If they are melted or sticky, use isopropyl alcohol and a cotton swab to carefully clean any residue from the pulleys and flywheels. Ensure all surfaces are clean and dry before installing new belts.
- Installing New Belts: Refer to the original belt path diagram (if available in the service manual) or carefully observe the path of the old belts before removal. Carefully stretch the new Thakker flat belts over the appropriate pulleys and flywheels. Ensure the belts are seated correctly and are not twisted. The belts should have a firm but not overly tight tension.
- Testing Mechanism: Before reassembling the casing, manually rotate the flywheel or motor pulley to ensure the new belts move smoothly and without obstruction. Observe the movement of the tape transport mechanism.
- Reassembly: Carefully reattach the outer casing, ensuring all screws are tightened securely. Do not overtighten.
- Initial Test: Connect the cassette deck to power and insert a test cassette. Play, fast forward, and rewind to verify proper operation. Listen for consistent speed and smooth tape movement.
4. Operating the Cassette Deck After Belt Replacement
After successful belt replacement, your Aiwa AD-WX 616 cassette deck should operate as intended. Refer to your original Aiwa AD-WX 616 user manual for specific operating instructions. Ensure cassettes are inserted correctly and that the tape is not slack before playback or recording.
- Playback: Insert a cassette and press the PLAY button.
- Recording: Ensure a blank or recordable cassette is inserted. Press RECORD and PLAY simultaneously.
- Fast Forward/Rewind: Use the FF and REW buttons for tape navigation.
5. Maintenance
Proper maintenance extends the life of your cassette deck and its new belts:
- Cleaning: Regularly clean the tape heads, capstan, and pinch rollers with a specialized tape head cleaner and cotton swabs. This prevents tape residue buildup that can affect playback quality and belt tension.
- Dust Prevention: Keep the cassette deck covered when not in use to prevent dust accumulation, which can interfere with moving parts and belts.
- Storage: Store the cassette deck in a cool, dry place, away from direct sunlight and extreme temperatures, which can degrade rubber components over time.
- Belt Inspection: Periodically (e.g., every few years, depending on usage) inspect the belts for signs of wear, stretching, or cracking.
6. Troubleshooting
If you encounter issues after installing the new belts, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tape speed inconsistent (too fast/slow) | Belts not seated correctly; residue on pulleys/flywheels; incorrect belt type (unlikely with this kit). | Re-open the deck and verify belt path and cleanliness of drive surfaces. Ensure belts are not twisted. |
| Tape not moving or stopping abruptly | Belts dislodged; mechanical obstruction; motor issue (less likely after belt replacement). | Check belt placement. Inspect for any foreign objects obstructing movement. |
| Squeaking or grinding noises | Belts rubbing against components; dry bearings; dirty capstan/pinch roller. | Ensure belts are not touching other parts. Clean and lubricate (if applicable and knowledgeable) bearings. Clean tape path. |
If problems persist, it is recommended to consult a qualified audio technician.
