Rexroth-type fan motor parts A10SF28... for Caterpillar 330D and 336D.
Detailed Information
------
I. Product Overview
TheRexroth A10SF28 fan motor partis a quantitative axial piston motor designed for hydrostatic transmissions in open and closed circuits. It converts hydraulic energy into mechanical energy, providing rotational motion and torque for industrial and mobile equipment. This model is part of Rexroth's A10FM series, known for its compact design, high power-to-weight ratio, and durability.

II. Key Features
1. Technical Specifications
• Type: Axial piston quantitative motor.
• Design: Swashplate structure for efficient power transmission.
• Pressure Rating:
• Nominal pressure: 280 bar.
• Peak pressure: 350 bar.
• Speed Range: Output speed proportional to input flow.
• Torque: Increases with pressure gradient.
• Mounting: SAE-standard mechanical and hydraulic connections.
2. Applications
• Suitable forwalking machinery(e.g., excavators, bulldozers) and industrial equipment (e.g., hydraulic presses, conveyors).
• Commonly used in cooling systems, fan drives, and auxiliary hydraulic circuits.
3. Compatibility
• While no direct confirmation of compatibility withCaterpillar 330D and 336Dwas found, Rexroth motors (e.g., A10VSO28 series) are frequently paired with Cat equipment in aftermarket applications.
• Verification Needed: Confirm compatibility with Cat's hydraulic system specifications (e.g., flow, pressure, and mounting interfaces).

III. Maintenance & Usage Tips
1. Maintenance
• Cleaning: Regularly remove dust and debris from the motor housing and cooling fins.
• Bearing Inspection: Check for wear or dryness; lubricate with recommended oil (e.g., 2-3 drops of sewing machine oil).
• Capacitor Check: Replace if swollen, leaking, or causing startup issues.
2. Usage
• Avoid operation in extremely humid or high-temperature environments.
• Ensure proper alignment and secure electrical connections.

IV. Compatibility Considerations
• Caterpillar 330D/336D: These excavators typically use Cat-branded hydraulic components, but aftermarket Rexroth motors (e.g., A10SF28) may be compatible if:
1. The motor's pressure/flow ratings match the Cat system.
2. Mounting dimensions and shaft configurations align.
3. Electrical controls (if applicable) are compatible.

V. Recommendations
1. Contact Manufacturers: Inquire with Rexroth and Caterpillar for official compatibility statements.
2. Check Aftermarket Suppliers: Some suppliers list Cat-compatible Rexroth motors (e.g., A10VSO28 for Cat 345D/349D).
3. Technical Documentation: Review hydraulic schematics and part manuals for both the motor and excavator.
