The Stellar D1204 Hydraulic Swing Motor is a genuine OEM hydraulic motor designed for the rotation system on compatible Stellar service cranes. It features an 8-cubic-inch displacement, 1-inch straight keyed shaft, and 90-degree port rotation.

If your crane rotates slowly, lacks swing power, moves inconsistently, or develops a hydraulic leak at the motor, the Stellar D1204 is the correct OEM replacement for compatible crane configurations. Replacing a worn swing motor restores controlled hydraulic rotation and dependable crane operation.

What This Part Is Used For

Slow or weak swing operation
Jerky or inconsistent rotation
Hydraulic fluid leaking from the motor
