If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar Industries 102101 9-Inch Cast Base Worm is an OEM replacement component designed for compatible Stellar crane swing-drive and gear-bearing assemblies using the Kinematics cast base system.

This heavy-duty worm gear component transfers rotational force through the crane swing-drive assembly, allowing controlled rotation of the crane. Replacing a worn or damaged worm helps reduce excessive movement, binding, uneven rotation, and other problems associated with wear in the crane rotation system.

What This Part Is Used For

The Stellar 102101 worm is used within compatible 9-inch Kinematics cast base gear-bearing assemblies. It works with the crane rotation system to transfer power through the swing drive and provide controlled movement of the crane around its base.
