Slewing Motor Assembly for Wacker Neuson 16 and Wacker Neuson 17 Mini Excavator

1. Product Overview

This slewing motor assembly is a complete factory-equivalent replacement unit specially engineered for Wacker Neuson 16 and Wacker Neuson 17 compact mini excavators. It is a fully integrated gerotor type slewing drive unit, including built-in parking brake, gerotor stator and rotor set, output shaft, seal kits and valve manifold. As the core component of the machine slewing hydraulic system, it provides stable torque for upper structure rotation. Our aftermarket motor strictly follows original OEM drawings and dimensions, enabling direct plug-and-play replacement without any machining or pipe modification, ideal for equipment overhaul and field repair.

Model Description

Complete swing motor assembly compatible with Wacker Neuson 16, Wacker Neuson 17 mini excavator models.

3. Working Principle

Pressurized hydraulic oil from the main hydraulic system enters the gerotor motor assembly. The oil drives the internal gerotor rotor to produce planetary orbital motion, converting hydraulic pressure into mechanical torque to rotate the excavator upper house. When the control lever is released, the spring-loaded multi-disc brake engages automatically to lock the output shaft, preventing free rotation on slopes. The integrated buffer valve absorbs pressure spikes during frequent start and stop actions, protecting the motor from hydraulic shock and extending service life.

4. Core Advantages

1. Fully identical to original dimensions, direct replacement for Wacker Neuson 16/17, no modification required.

2. Integrated wet brake design, reliable holding performance on inclined working surfaces.

3. Precision gerotor components, low internal leakage and smooth rotation without jitter.

4. Compact structure design, perfectly fits the limited installation space of micro excavators.

5. Complete pre-assembled unit, easy installation and greatly shortening maintenance time.

6. Stable performance under frequent cyclic operation in landscaping and narrow job sites.

7. Cost-effective alternative compared with original factory motor.

5. Application Range

This slewing motor assembly is exclusively used in the slewing hydraulic system of Wacker Neuson 16 and 17 ton class mini excavators, widely used in indoor renovation, municipal pipe work, garden construction and tight-site engineering projects.

6. Common Faults & Replacement Suggestion

Common defects include weak slewing power, slow rotation, oil leakage from brake section, free drifting when stopping. Replace the complete motor assembly directly to restore machine performance, no need to disassemble internal components separately.
