RITO 4330222 Swing Motor EX200-5 EX200-2 EX200-3 Slewing Motor Assembly 4330222 Hydraulic Swing Motor Rotary Motor

Sluggish swing rotation kills excavator cycling speeds, turning profitable aggregate mining into a losing venture. Internal pressure bypass inside old rotary motors wastes valuable engine horsepower and leaks costly oil. Restore crisp positioning and tight operator controls using our robust 4330222 motor assemblies.

Excavator Hydraulic Part

FAQ

Q: Our older machine uses an older hydraulic layout; will this motor align with factory plumbing?
A: This assembly matches the factory port footprint exactly. Oil supply, return, and pilot brake lines align perfectly with original hoses, removing the need for custom adapters or modifications.
 
Q: What flushing process is required if the previous swing motor suffered a internal breakdown?
A: You must flush the entire hydraulic loop, clean the oil reservoir, and replace all system filters. Any leftover metal particles will migrate into the new motor and damage the piston faces.
 
Q: Are the internal valve plates and cylinder blocks replaced with new parts during assembly?
A: Yes, all critical wear surfaces feature brand-new, precision-ground components. This ensures maximum volumetric efficiency and factory-standard operating pressure.
 
Q: How does the unit handle extreme heat during continuous truck-loading shifts?
A: The high-grade alloy housing and optimized flow channels quickly dissipate heat into the return line. This design maintains steady oil viscosity and reliable performance up to 120°C.
 
Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
