When your Yanmar excavator's upper structure is drifting, lagging, or losing slewing torque, the swing motor is almost always to blame. We supply heavy-duty, direct-fit complete hydraulic swing motor assemblies engineered specifically for the Yanmar VIO / SV / U series lineup.
- Massive Slewing Torque: Engineered to original factory performance metrics to deliver rapid acceleration and unwavering power — even when swinging heavy loads on steep terrain.
- Zero-Drift Hydraulic Braking: Equipped with premium integrated relief valves and mechanical parking brake groups. When you stop the joystick, the house stops — no overshoot, no dangerous drift.
- Complete Drop-In Assemblies: Our units come fully assembled with the complete motor group, integrated valve block, and heavy-duty splined drive shaft — ready to mate with your existing swing gearbox.
We utilise Kawasaki M2X / Yanmar OEM swing motor technology across this range, with exact-fit configurations for each Yanmar model and generation.
Give our heavy machinery parts team your Yanmar model number and machine serial number — we'll quickly locate the exact direct-fit replacement to eliminate your downtime.
