Product Description
E307E E308E Swing Motor 393-2179/4Y0212/4Y-0212/486-1575
The E307E Swing Motor (Part Numbers: 393-2179/4Y0212/4Y-0212/486-1575) is a high-performance hydraulic motor designed for excavator applications. This Motor GP-Swing component is part of the 388-9128 Power Train Assembly, ensuring reliable operation in demanding construction environments.
Reverse-Prevention Safety Feature
This excavator swing motor incorporates a built-in reverse-prevention valve that eliminates unintended reverse rotation, preventing operational errors and safety hazards.
- One-way valve design ensures hydraulic oil flows in only one direction
- Prevents motor reversal due to external forces or hydraulic fluctuations
This critical safety feature is especially important during heavy lifting operations where reverse rotation could cause load drops and serious accidents. The high-flow capacity valve maintains normal motor operation and response speed while delivering reliable performance under high hydraulic pressure and frequent use conditions.

Hydraulic Motor Applications
Hydraulic motors are essential components in earthmoving equipment including excavators, backhoe loaders, skid-steer loaders, forklifts, heavy dump trucks, and bulldozers. They power hydraulic cylinders that extend and retract during various operational cycles.
Swing Brake Operation
The swing brake features a multi-disc and plate assembly located in the first stage planetary gear. This spring-applied, hydraulically-released system functions as a parking brake and is not designed for cyclic service braking. Discs and plates are lubricated by the release signal oil for optimal performance and longevity.
