Stellar Industries 45117 Hydraulic Rotator Motor – KPCC Key Shaft (Ref. PN 45111

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 45117 Hydraulic Rotator Motor is a high-torque replacement drive motor designed for KPCC rotator assemblies on Stellar service equipment and cranes. Built with a keyed output shaft, this motor delivers precise rotational torque and smooth speed control during heavy-duty lifting and positioning operations.

Constructed with high-strength cast housing and durable internal seals, this unit handles continuous hydraulic pressures while resisting internal fluid bypass. Please note that this unit includes the key shaft rotator motor only (no coupler included) and serves as a direct system reference for PN 45111 assemblies.

What This Part Is Used For

The Stellar 45117 motor drives the rotation mechanism on KPCC rotator heads, enabling continuous or controlled 360-degree rotation for crane blocks, hooks, and material handling attachments.

Common Reasons For Replacement

• Slow, jerky, or stalled rotator operation under normal hydraulic load

• Severe internal fluid bypass causing loss of rotational torque

• External hydraulic oil leaks around shaft seals or port housings

• Worn or sheared keyway on the motor output shaft

• Excessive noise, grinding, or cavitation during rotation

• Total motor failure due to fluid contamination or thermal breakdown

Compatible Applications

Designed for Stellar Industries hydraulic crane systems, service truck units, and KPCC rotator head assemblies requiring a keyed shaft rotator motor (Part # 45117 or system Ref. # 45111). Always check equipment model, shaft size, port type, and hydraulic flow specifications before ordering.
