Introduction

the assembly includes:

a drive motora small gear systema drive wheela motor controllerthe R75’s suspension system

Each of these components can be replaced individually, however, you will rarely find a single component being sold as a replacement, whereas the complete assembly can be ordered.

You may want to remove the drive assembly in order to replace a failed drive motor or to clean out hair or debris from the drive wheel. If a drive motor has failed, you should notice your robot’s ability to move become severely impaired, if not fail entirely.

It is important to occasionally inspect the wheels for any sort of wear and debris build up.

Where I can buy the Shark ION Robot R75 Drive Wheel Assembly Replacement?

Thanks for your help!

Do you know what the drive wheel motor cable is (see Step 6)? It’s a 6 pin to 5 pin and the grooves are on the thin side and pitch of ~1.4mm. Possible a JST ZH?

I appreciate the step-by-step instructions with pictures… this was very helpful. However, my rv750 doesn’t have the screws by the wheel assembly.

I’ve removed the screws, but it appears that I will need to separate the bottom from the top to access the wheel assemblies. Do you have a step=by step for the rv750 that has the wheel assembly enclosed?
