Central sprocket on frame for the 4D single-brush sander 

The central pinion on the frame is an essential mechanical part located at the centre of the machine's frame. Its main role is to transmit the rotary motion of the motor to all the rotating components of the sander, including the accessory plate.

The central pinion is generally responsible for distributing the motor's rotary motion to different parts of the sander, enabling the machine to perform the various sanding, polishing or cleaning tasks.

As for when to consider changing the centre gear on the frame of a single-brush sander, here are some signs that it may need replacing:

1. Abnormal noises: If you hear unusual noises such as grinding, rattling or rubbing coming from the sander as it runs, this may indicate that the centre gear is worn or damaged.

2. Excessive play: if you notice excessive play or side-to-side movement in the centre sprocket, this may be a sign that it is worn and no longer transmitting motion correctly.

3. Difficulty turning accessories: if the accessory tray or other sander components have difficulty turning freely, this may be due to a problem with the centre gear.

4. Unsatisfactory performance: if you notice a significant drop in the sander's performance, with less satisfactory sanding, polishing or cleaning results, this may be linked to a problem with the centre gear.

If you experience any of these problems or suspect that the centre sprocket on the frame is defective, it is recommended that you contact Repex Floor's after-sales service department to carry out a diagnosis and replace the centre sprocket if necessary. Make sure you use original Repex Floor spare parts to ensure perfect compatibility with your single disc sander and to obtain optimum performance.
