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 27183 Worm is a replacement rotation-drive component for compatible Stellar 3200 service cranes equipped with the Gear Products rotation assembly. It corresponds to Gear Products component number 170-10051-1.

This precision-machined worm transfers power from the hydraulic swing motor to the crane’s rotation gear. Replacing a worn worm helps restore smooth crane rotation, reduce excessive backlash, and prevent further damage to the rotation-bearing assembly.

What This Part Is Used For

The Stellar 27183 worm drives the crane rotation gear, allowing the boom assembly to rotate under hydraulic power. It works within the crane’s geared rotation system to provide controlled swing movement and load positioning.

Common Reasons For Replacement

Excessive play or backlash in the rotation system
Worm teeth are worn, chipped, or damaged
Grinding or clicking noise during crane rotation
Boom rotates slowly or binds in certain positions
Rotation assembly was operated without adequate lubrication
Worm damaged by a failed bearing or swing motor
