Machine Compatibility:

Takeuchi TB215R Mini Excavator

Takeuchi TB216 Mini Excavator

Condition: Brand New Original / Premium OEM Specification Equivalent

2. Technical Specifications
Type: High-Performance Geroler / Disc Valve Hydraulic Motor (Eaton T Series Architecture)

System Output: Factory-matched displacement and pressure capabilities designed specifically to provide optimal rotational torque for Takeuchi 1.5 to 1.7-ton mini excavators.

Integrated Valve Network: Built-in dual crossover cushion relief valves and anti-cavitation blocks engineered to smoothly arrest cabin inertia and eliminate hydraulic shock during quick stops.

Interface Mount: Precision-machined 2-bolt or 4-bolt pilot flange configuration paired with a high-strength spline shaft designed to slip directly into the factory upper-structure slew gear drive.

3. Critical Installation Requirements
Motor Case Priming (Mandatory)
Before starting the engine or activating the swing control joystick, you must manually pre-fill the swing motor casing with fresh, clean hydraulic fluid through its highest available case drain port. Running an Eaton disc-valve motor completely dry—even for a few moments—will cause immediate frictional scoring on the internal wear plates and lead to internal pressure bypass.

Verify Case Drain Line Clearance
Thoroughly inspect the low-pressure case drain hose leading back to the hydraulic oil reservoir. Ensure it is completely free of sharp bends, kinks, or inner wall collapses. Any sudden restriction in this line creates excessive housing backpressure, which will instantly blow out the motor's main shaft seal.

Gear Pinion & Slew Ring Lubrication
Ensure that the mounting pocket on the Takeuchi chassis is clear of dirt and rust. Apply a generous, uniform coating of premium heavy-duty lithium gear grease to the motor’s output spline shaft pinion and the matching teeth of the upper structure slew ring gear during installation.

Fluid & Circuit Decontamination
If the previous swing motor failed due to a severe mechanical breakdown, you must drain the hydraulic reservoir, flush the main control valve's swing spool circuit hoses, and clear the oil cooler. Abrasive metal particles left behind in the old fluid will rapidly score and destroy the newly installed motor.

4. Frequently Asked Questions (FAQ)
Q: Are part numbers 19031-30600 and 19039-07000 fully interchangeable?
A: Yes. These numbers represent standard Takeuchi engineering revisions and production updates for the TB215R and TB216 excavator lines. Both cross-reference directly to the foundational Eaton T247-MA3B02 platform, keeping the exact same physical mounting space and performance output.

Q: My Takeuchi TB216 jerks heavily or "over-swings" when I release the control joystick. Will this fix it?
A: Yes. Over-swinging, drifting on slopes, or harsh structural shuddering during a stop indicates that the integrated crossover cushion relief valves inside the motor housing have worn down or suffered surface scoring. A complete replacement unit restores precise stopping and holding power.

Q: Does the swing motor arrive fully assembled and ready to bolt on?
A: Yes. Our premium assemblies are shipped complete with the factory-calibrated valve blocks and internal dynamic groups pre-tested for immediate, plug-and-play installation.

5. Shipping & Logistics
Packaging: Thoroughly preserved with anti-corrosion storage oil, sealed with heavy-duty plastic port plugs to prevent dirt ingress, and packaged securely inside an export-safe protective box.

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