A complete swing motor replacement isn't always necessary. Replacing the internal rotating group, mechanical brake plates, or relief valves is a highly cost-effective way to restore factory-spec slewing precision at a fraction of the cost of a full unit.
We supply a comprehensive range of precision internal components for swing motors used across the Develon / Doosan DX / DH / Solar series lineup — including Mottrol (Doosan) / Kawasaki M2X units fitted to both current and legacy generations.
Why Choose Our Develon / Doosan Swing Motor Parts?
- Micron-Level Tolerance Matching: Every component is engineered to exact OEM dimensions, ensuring seamless integration with your existing motor housing and valve block.
- Pre-Packaged Overhaul Kits: We offer complete swing motor rebuild kits — cylinder block, pistons, set plate, valve plate, and full seal kit — so you can source everything for a full overhaul in a single order.
- Protect Your Hydraulic Circuit: Replacing worn friction discs and micro-scored valve plates early prevents metallic debris from circulating through the main hydraulic system — protecting your main control valves from costly secondary damage.
Provide us with your Develon / Doosan machine model, serial number, or the data tag from your swing motor casing — and we'll match the exact internal components you need.
