مخفض آلية الدوران لـ حفارة صغيرة Kubota KX10

1. Product Identification
Component: Swing Motor Device Assembly

Machine Compatibility: Kubota KX10 Mini Excavator

Condition: High-Quality Aftermarket New

System Function: Provides the rotational hydraulic force required to swing the excavator's upper superstructure smoothly.

2. Technical Specifications
Type: Fixed Displacement Axial Piston Motor

Design Integration: Incorporates the hydraulic motor block, built-in swing relief valves, and mechanical anti-drift parking brake mechanism in one compact frame.

Performance: Set to original Kubota factory torque parameters to ensure precise stopping power and control on slopes.

Structural Build: Engineered with high-strength castings and high-load bearings to match standard OEM mounting configurations.

3. Critical Installation Requirements
Case Priming (Mandatory)
Before operating the machine, manually fill the swing motor housing with clean hydraulic oil through the highest case drain port. Running an axial piston motor dry for even a few seconds will instantly score the wear plates and ruin the piston slippers.

Verify Case Drain Line Clearance
Check that the case drain return line back to the hydraulic reservoir is entirely unobstructed. Any backpressure or restrictions in this line will immediately cause the main shaft seal to blow out.

Slew Ring Pinion Greasing
Clean the excavator chassis mounting face thoroughly. Apply a generous coating of heavy-duty lithium grease to the output shaft pinion gear and the main swing bearing ring teeth during assembly.

Hydraulic Decontamination
If the previous motor failed mechanically, you must drain the hydraulic reservoir, flush the supply lines, and clean out any trapped metal contaminants to protect the new aftermarket unit from premature abrasive wear.

4. Frequently Asked Questions (FAQ)
Q: Will this aftermarket swing motor fit my Kubota KX10 without modifications?
A: Yes, this unit is engineered as a direct premium replacement, meaning the mounting flange layout, output pinion tooth profile, and hydraulic port locations match the original factory design for a seamless "bolt-on" installation.

Q: My mini excavator cabin drifts slowly when I am trying to dig or park on an incline. Will replacing the motor fix this?
A: Yes. Slow swing drift is usually caused by worn internal mechanical brake friction discs or leaking relief valves within the swing motor housing. Replacing the complete assembly restores full holding power.

Q: How is this motor protected against damage during shipping?
A: The assembly is treated with rust-inhibiting storage oil, sealed with heavy-duty port plugs to prevent dirt entry, wrapped in a moisture barrier, and secured inside a cushioned, high-strength shipping box.

5. Shipping & Logistics
Packaging: Reinforced export-grade protective packaging.

Transit Time: Global express air freight via DHL/FedEx/UPS typically delivers within 3 to 7 business days directly to your workshop.
