2. Setup and Installation
Proper installation of the drive belt is crucial for the correct operation of your Marantz TT-170 turntable. Please follow these steps carefully.
2.1 Before You Begin
- Safety First: Always unplug your turntable from the power outlet before performing any maintenance or installation.
- Tools: You may need a small flathead screwdriver or a similar tool to gently lift the platter, and a clean cloth.
- Work Area: Ensure you have a clean, well-lit, and stable work surface.
2.2 Installation Steps
- Remove the Turntable Platter: Carefully lift the rubber mat from the turntable platter. Locate the two small holes on the platter. Using your fingers or a small tool, gently lift the platter straight up and off the spindle. Set it aside on a soft, clean surface.
- Remove the Old Belt (if present): If an old belt is still installed, carefully remove it from around the motor pulley and the sub-platter (the smaller platter underneath the main one). Dispose of the old belt responsibly.
- Clean the Pulley and Sub-Platter: Use a clean, lint-free cloth to wipe down the motor pulley and the rim of the sub-platter where the belt will sit. This removes any residue that could affect belt performance.
- Install the New Belt:
- Carefully stretch the new Vintage Electronics belt around the rim of the sub-platter.
- Align the belt so it sits evenly around the sub-platter.
- Gently guide the belt onto the motor pulley. Ensure it is not twisted and sits securely on both the sub-platter and the motor pulley.
- Replace the Main Platter: Carefully place the main platter back onto the spindle, ensuring it seats correctly and does not pinch the belt. Rotate the platter manually a few times to ensure the belt is properly seated and moves freely without obstruction.
- Test the Turntable: Plug the turntable back into the power outlet. Select a speed (e.g., 33 RPM) and start the turntable. Observe if the platter rotates smoothly and at a consistent speed.
If you encounter any resistance or unusual noises during installation or testing, recheck the belt's seating and ensure no components are misaligned.
3. Operating Considerations
While the drive belt itself does not have operational controls, its proper function is integral to the turntable's performance. Ensure the turntable is placed on a stable, level surface to prevent undue stress on the belt and motor. Avoid manually stopping or slowing the platter while it is in motion, as this can stretch or damage the belt over time.
4. Maintenance
Regular maintenance of your turntable belt will ensure longevity and consistent audio quality.
- Inspection: Periodically inspect the belt for signs of wear, cracking, stretching, or loss of elasticity. A worn belt can lead to inconsistent playback speed.
- Cleaning: If the belt appears dusty or dirty, gently wipe it with a clean, dry, lint-free cloth. Avoid using harsh chemicals or solvents, as these can degrade the rubber material.
- Storage: If the turntable is to be stored for an extended period, it is advisable to remove the belt to prevent it from developing flat spots or becoming stretched.
5. Troubleshooting
If you experience issues with your Marantz TT-170 turntable after belt installation, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Platter not spinning or spinning slowly. | Belt not properly seated, belt twisted, or belt too loose. | Unplug the turntable, remove the platter, and re-seat the belt ensuring it is flat and correctly positioned on both the sub-platter and motor pulley. |
| Inconsistent playback speed (wow and flutter). | Belt slipping, dirty motor pulley/sub-platter, or worn belt. | Clean the motor pulley and sub-platter. Ensure the belt is free of grease or debris. If the belt is old, consider replacement. |
| Unusual noise during operation. | Belt rubbing against components, or foreign object. | Inspect the belt path for any obstructions. Ensure the belt is not twisted or rubbing against the platter or chassis. |
If these steps do not resolve the issue, please contact Vintage Electronics customer support.
