Hydraulic Spare Parts for Toshiba Swing Motor

Product Overview

These hydraulic spare parts are overhaul components specially for Toshiba swing motor SG02, SG04, SG08. The repair kit includes valve plate, iron ring, belleville spring, spring pressure plate and shim washer. These critical wearing parts directly affect the operation of the hydraulic system, transferring torque to drive the slewing action of construction Machine. When these components suffer wear, scratch, fatigue deformation or breakage, the swing motor will produce symptoms such as weak rotation, internal leakage, slow slewing speed, abnormal noise and poor braking performance. This set of replacement accessories is suitable for motor disassembly, repair and overhaul.

Technical Specifications

- Applicable Motor: Toshiba Swing Motor SG02, SG04, SG08

- Parts List: Valve plate, iron ring, belleville spring, spring pressure plate, shim washer

- Working Medium: Anti‑wear hydraulic oil

- Matching Equipment: Excavator slewing assembly

- Installation: Fit original assembly structure, no extra modification

- Usage: Swing motor internal overhaul and maintenance

Working Principle

During motor operation, the valve plate realizes oil‑distribution switching for high‑pressure and low‑pressure hydraulic oil inside the hydraulic system. The belleville spring, spring pressure plate and shim washer apply pre‑tightening pressure to keep close contact between friction pairs. The iron ring plays positioning and sealing auxiliary function. All parts cooperate closely to reduce clearance leakage, guarantee stable pressure transmission, and ensure the swing motor outputs steady torque for the Machine. Once wearing parts are damaged, the matching clearance increases, and the overall working efficiency of swing motor declines sharply.

Core Advantages

1. Strict dimensional tolerance, fully match original Toshiba swing motor SG02, SG04, SG08 assembly requirement.

2. High‑strength alloy material, good wear‑resistance and anti‑fatigue performance under continuous cyclic impact load.

3. Precise flatness for valve plate, effectively control internal leakage of hydraulic system.

4. Complete combined spare parts, support full disassembly overhaul, reduce whole‑motor replacement cost.

5. Easy onsite assembly, ideal for excavator maintenance shops and equipment repair work.

Application Scope

Mainly apply to Toshiba SG02, SG04, SG08 swing motor fitted on multiple brand excavators. Widely used in earth‑moving, municipal engineering and other construction‑site Machine repair projects. These wearing components are essential accessories to restore normal slewing performance of swing motor.
