E307C/E308C KYB MSG-44P-21-950014 185-0360 Y（E307C/191-5576）（E308C 199-4585）PART OF 171-9290 DRIVE GP-SWING

The E307C/E308C KYB MSG-44P-21-950014 185-0360 excavator swing motor is equipped with a built-in reverse-prevention valve that prevents unintended reverse rotation, eliminating 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 safety feature is particularly critical 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 providing reliable performance under high hydraulic pressure and frequent use conditions.

Each unit undergoes thorough inspection and detailed photos are provided for buyer confirmation before shipping to ensure product quality and satisfaction.

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.

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.

Our facility includes over 4000 square meters of three-dimensional warehouse space plus 2000 square meters of outdoor storage, ensuring adequate inventory levels and rapid response to customer requirements. Fast delivery is our competitive advantage.
