Working Principle
The swing motor is the core power unit of the excavator rotation hydraulic system. Hydraulic pressure drives the inner & outer rotors to rotate, power is transmitted through vertical shaft and connecting gear, and outputs torque to drive the upper body of the Machine to rotate smoothly .
When vertical shaft, connecting gear or inner & outer rotors are worn, the swing motor will appear internal leakage, insufficient torque, abnormal noise and rotation lag. Replacing these matched Yanmar 17 swing motor parts can recover the original working performance of the hydraulic system.
Core Advantages
1. Strict dimensional matching with original swing motor, direct installation, no need for machining or modification on the Machine.
2. High‑quality alloy steel material, good wear resistance, adapts to harsh working conditions of construction site hydraulic system.
3. Complete set of core wear‑parts, convenient for on‑site overhaul, effectively reduce maintenance downtime of the Machine.
4. Cost‑effective aftermarket alternative, stable performance, suitable for routine repair and spare‑part stocking.
5. Standard manufacturing process, each part is inspected before delivery to guarantee reliability for the whole hydraulic system.
Application Range
Yanmar 17 Swing Motor Parts are widely used for repair and overhaul of Yanmar Vio17 mini‑excavator swing hydraulic system. Applied in construction sites, farmland engineering, municipal construction and other working scenarios of the Machine. Widely supplied to excavator repair workshops, equipment dealers and global spare‑parts distributors.
