Eaton 104-3130-006 Torqmotor Hydraulic Motor - Replacement Standard 2 Bolt 31.75mm 14 Tooth 0.875-14 UNF-2B SAE O-RING

1. High-Performance Design

• Optimized gear geometry: Delivers smooth torque output with reduced pulsation
• Precision manufacturing: Strict tolerance control ensures high volumetric efficiency and extended service life
• Balanced load distribution: Minimizes bearing and gear wear

2. Reliable Durability

• Heavy-duty bearing system: Supports high radial and axial loads
• Hardened gears: Wear-resistant treatment extends service life
• Robust housing: Impact and vibration-resistant design

3. Installation Convenience

• Standardized mounting: 2-bolt design simplifies installation and maintenance
• Universal shaft size: 31.75mm shaft diameter compatible with diverse equipment
• Standard SAE ports: Simplifies piping connections

4. Application Adaptability

• Wide Temperature Range: Operates from -40°C to +100°C
• Multi-Fluid Compatibility: Suitable for mineral oil, synthetic hydraulic fluid, and biodegradable fluids
• Multiple Mounting Orientations: Allows installation in any direction

• Installation Notes

1. Alignment Requirements: Ensure precise alignment between the motor shaft and drive components (±0.1mm).
2. Support Requirements: Avoid excessive radial loads on bearings (refer to manual for limit values).
3. Drainage Piping: The housing drain port must be independently routed back to the oil tank, maintaining low pressure.
4. Initial Start-up: Install after system flushing; perform low-speed running-in during first operation.

• Maintenance Recommendations

1. Fluid Cleanliness: Maintain ISO 18/16/13 or better cleanliness level
2. Regular Inspection: Check for shaft seal leakage, abnormal noise, or performance degradation
3. Storage Recommendations: Fill with anti-corrosion hydraulic oil before long-term storage; seal all ports
