3. Product Overview
The plastic idlers are crucial components of your RC tank's track system. They are located at the front and rear of the track assembly, guiding the tracks and maintaining proper tension. These idlers are manufactured from durable plastic, offering a balance of strength and weight for your 1/16 scale tank.

4. Setup and Installation
Follow these general steps for replacing the plastic idlers on your Henglong 1/16 scale RC tank. Specific tank models may have minor variations.
4.1 Tools Required
- Small Phillips head screwdriver
- Pliers (optional, for track pin removal)
- Tweezers (optional, for small parts handling)
4.2 Installation Steps
- Prepare the Tank: Ensure the RC tank is powered off and the battery is disconnected. Place the tank on a stable, clean surface.
- Remove Tracks: Carefully detach the tracks from the drive sprockets and road wheels. This usually involves removing a track pin or opening a track link.
- Remove Old Idlers: Locate the screws or pins securing the existing idlers. Unscrew or remove these fasteners and carefully detach the old idlers from the tank chassis. Note the orientation of any washers or bushings.
- Install New Idlers: Position the new plastic idlers in the correct location. Ensure they align with the mounting points. Secure them using the original screws or pins. Do not overtighten.
- Reattach Tracks: Guide the tracks back onto the road wheels, idlers, and drive sprockets. Ensure the tracks are properly tensioned; they should not be too loose or too tight. Reconnect the track links.
- Test Functionality: Power on the tank and perform a slow test drive to ensure the tracks move smoothly and the new idlers function correctly. Check for any binding or unusual noises.
5. Operating Considerations
The idlers are passive components that guide the tank's tracks. Their proper function is essential for smooth movement and track integrity. Ensure that the tracks are always correctly seated on the idlers during operation. Avoid operating the tank in conditions that could cause excessive strain or damage to the track system, such as very rough terrain with sharp obstacles that could snag the tracks or idlers.
6. Maintenance
Regular maintenance of your idlers will extend their lifespan and ensure consistent performance.
- Cleaning: After each use, especially in dusty or dirty environments, clean any debris (dirt, grass, small stones) from around the idlers and tracks. A soft brush or compressed air can be effective.
- Inspection: Periodically inspect the idlers for signs of wear, cracks, or damage. Check that they spin freely and are securely attached.
- Track Tension: Ensure the track tension remains appropriate. Overly tight tracks can put undue stress on the idlers and other track components, while loose tracks can derail.
- Storage: Store the tank in a clean, dry environment away from direct sunlight and extreme temperatures to prevent material degradation.
7. Troubleshooting
Here are some common issues related to idlers and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tracks frequently derail | Loose track tension, worn idler, debris in tracks | Adjust track tension, inspect/replace idlers, clean tracks thoroughly |
| Idler does not spin freely | Debris lodged, overtightened screw, damaged axle | Clean debris, loosen screw slightly, inspect for damage and replace if necessary |
| Unusual noise from track area | Worn idler, foreign object, misaligned track | Inspect idlers for wear, remove foreign objects, check track alignment |
