4. Ghid de instalare
Replacing cassette deck belts requires careful handling and attention to detail. If you are unsure about any step, it is recommended to seek professional assistance.
4.1. Pregătire
- Deconectați alimentarea: Ensure the Aiwa AD-WX 220 cassette deck is completely unplugged from the power outlet before beginning any work.
- Mecanismul intern de acces: Carefully open the cassette deck's casing to gain access to the drive mechanism. This may involve removing screws from the bottom or rear panel. Refer to your specific deck's service manual if available.
- Identificați curelele vechi: Locate the existing drive belts. They are typically rubber bands connecting motors to flywheels and capstans. Note their routing paths.
4.2. Belt Removal and Cleaning
- Scoateți curelele vechi: Gently remove all old, stretched, or broken belts. Be careful not to damage any surrounding components.
- Clean Pulley Surfaces: Use isopropyl alcohol and a cotton swab or lint-free cloth to thoroughly clean all surfaces where the belts make contact (motor pulleys, flywheels, capstans). Old belt residue can be sticky and cause new belts to slip. Ensure surfaces are completely dry before proceeding.
4.3. New Belt Installation
- Instalați curele noi: Carefully route the new flat and square belts according to the original configuration. Ensure they are seated correctly on all pulleys and flywheels without twists or kinks. The flat belts typically drive the main capstan, while square belts often handle counter or auxiliary functions.
- Verificați tensiunea: Once installed, gently rotate the flywheels by hand to ensure the belts move smoothly and have appropriate tension. They should be snug but not overly tight, and should not slip.
4.4. Reasamblare și testare
- Reassemble Casing: Carefully reassemble the cassette deck's casing, asigurându-vă că toate șuruburile sunt strânse bine.
- Conectare alimentare: Plug the cassette deck back into the power outlet.
- Funcții de testare: Insert a cassette tape and test all functions: Play, Fast Forward, Rewind, and Stop. Listen for consistent speed and smooth operation. If any issues arise, disconnect power and re-inspect the belt installation.
5. Operating Considerations (Post-Installation)
While this kit provides replacement parts, proper operation of your Aiwa AD-WX 220 cassette deck relies on the correct installation of these belts. After installation, observe the following:
- Speed Consistency: Ensure playback speed is consistent and does not fluctuate.
- Smooth Transport: Fast forward and rewind functions should operate smoothly without excessive noise or stalling.
- No Wow or Flutter: Listen for any audible variations in pitch (wow and flutter), which could indicate improper belt tension or installation.
6. Întreținere
To maximize the lifespan of your new belts and the performance of your cassette deck:
- Inspecție regulată: Periodically inspect the belts for signs of wear, cracking, or stretching. The lifespan of belts can vary depending on usage and environmental conditions.
- Curăţenie: Keep the internal mechanism of the cassette deck free from dust and debris. Dust can accumulate on pulleys and belts, leading to slippage or premature wear.
- Evitați temperaturile extreme: Store and operate the cassette deck in a stable environment, avoiding extreme temperatures or humidity, which can degrade rubber components.
7. Depanare
If you encounter issues after installing the belt kit, consider the following:
| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| Tape speed too slow or inconsistent | Belts not properly seated; residue on pulleys; incorrect belt routing. | Re-open deck, verify belt routing and tension. Clean pulleys again. |
| Fast Forward/Rewind not working | Specific FF/RW belt dislodged or not installed correctly. | Check the routing and tension of the square belts, which often handle these functions. |
| Squeaking noise from mechanism | Dry bearings or friction points; belt rubbing against casing. | Ensure belts are not rubbing. Lubricate moving parts if necessary (refer to deck's service manual). |
