Motor and gearbox supplied as a matched unit eliminates oil cross-contamination risk and ensures correct motor-to-gearbox port alignment and torque transfer.
New rotating group in the motor section restores rated motor displacement, eliminating the bypass-driven oil overheating that progressively degrades 210X3E swing speed.
Planetary gearbox assembled with controlled backlash to OEM spec, eliminating the cab jolt at swing reversal that characterises worn Link Belt 210-series gearboxes.
KRC10221 covers 210X3E, 210X2, 210X3 and 215X3E for direct bolt-on replacement without swing assembly housing modification.
FAQ
Q: How do I diagnose motor versus gearbox failure in the KRC10221 assembly?
A: Measure motor case-drain flow. High drain flow confirms motor wear; normal drain flow with gear noise and metal in gearbox oil confirms gearbox failure. The complete assembly covers both failure modes.
Q: Does KRC10221 include the swing brake valve?
A: Yes. The complete swing motor assembly includes the integrated brake valve block as supplied. Confirm the assembly scope with our team if your application uses an external brake valve.
Q: What oil should I use in the KRC10221 gearbox section?
A: Use EP 90 or EP 140 gear oil. Fill to the specified level and change after the first 50-hour break-in period.
Q: How to confirm KRC10221 fits my 210X3E?
A: Match part number KRC10221, motor flange bolt pattern and housing mounting dimensions. Provide machine serial number for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.

Track motor delivering low tractive force or the machine dragging one track? A worn TM22 series travel motor loses volumetric efficiency as barrel and piston shoes wear, reducing shaft torque output below what the machine needs on grades. RITO's TM22 travel motor assembly restores rated torque and full bilateral travel capability.

JCB JS130 or JS150LC actuators hunting or one function completely inoperative? A worn JS130FPF control valve loses spool metering accuracy, causing the flow-sharing system to lose priority balance and making smooth combined-function operation unpredictable. RITO supplies this precision control valve to restore correct metering and flow prioritisation across all JS130-series functions.

Pilot pressure low or auxiliary circuit losing flow on your excavator? A worn CBTLYB-F412.5 gear pump loses internal clearance, allowing slip flow to grow until pilot or charge circuit demand cannot be met. RITO supplies this heavy-duty CBTLYB-series gear pump to restore rated pilot or auxiliary flow for reliable main valve and circuit control.
