Gear-Ring (101-TEETH) 148-4580 Gear-Ring (66-TEETH) 7Y-1090 of 455-2770, 590-3901 Drive GP-Final

E390F/E390D Travel Motor Assembly. As a high-grade replacement spare part for heavy-duty excavators, this travel drive model is professionally optimized and precisely calibrated to perfectly fit E390F/E390D specification models.

Differing from conventional hydraulic motor assemblies, this unit adopts upgraded hydraulic transmission technology and integral reinforced structural craftsmanship. It is purpose-built for rigorous heavy-load construction conditions, effectively delivering stable output performance, extended service lifespan, and improved overall operation reliability.

Boasting excellent compatibility and superior comprehensive performance, it serves as a cost-effective premium replacement solution for original equipment parts.

The motor and mounting group 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 safety feature is 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.
