Bosch Rexroth R986110939 (Series 52/53) is a direct OEM replacement for BOBCAT 6675294, engineered to restore specified hydraulic output with reliable fit and performance consistency.
Technical Specifications
Flow Performance
With a 71 cc displacement, R986110939 delivers predictable volumetric output per revolution for stable actuator response and controllable machine motion. At speeds up to 2600 max, the displacement supports consistent flow generation across the operating range. The Series 52/53 design targets repeatable hydraulic performance under load.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, the unit is built to maintain output stability under high-load transients. Operation up to 2600 max speed supports sustained duty cycles while preserving performance consistency within the specified limits. The 48.5 weight reflects a robust assembly intended for pressure-capable service.
Installation
Designed as an OEM-form replacement for BOBCAT 6675294, this component is intended to install with standard mounting interfaces and hydraulic connections. As a direct replacement, it is specified to fit without machine modifications when replacing the original part number.
Features and Benefits
- 71 cc displacement: Provides a fixed, repeatable volume per revolution to support stable flow delivery and predictable system response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high working pressures and short-duration pressure spikes to maintain hydraulic function during demanding load events.
- 2600 max speed rating: Enables sustained operation across a broad speed range while maintaining consistent hydraulic output within rated limits.
Operational Information
Operate within the specified nominal (3600 PSI) and peak (4600 PSI) pressure limits and up to 2600 max speed to maintain expected performance. Reliability is achieved by keeping system conditions aligned with these ratings and using standard hydraulic fluid cleanliness practices appropriate to the machine.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Compatibility & Applications
Direct Replacement Information
This Rexroth R986110939 replaces BOBCAT 6675294 in mobile hydraulic closed-loop hydrostatic drive and implement circuit applications.
- Mobile hydraulic systems requiring 71cc displacement variable flow control (see related piston pumps for similar architectures)
- Circuits operating at 3600 PSI nominal pressure for propulsion or implement functions
- Axial piston variable pump applications supporting hydrostatic transmissions, travel drives, and auxiliary/implement hydraulic circuits
- Equipment requiring up to 2600 max pump speed in compact mobile hydraulic packages
Common Applications
This Bosch Rexroth R986110939 is commonly used in:
- mobile hydraulics
- compact construction equipment (skid-steer/track loaders)
- construction equipment hydraulic drive and auxiliary circuits
- agricultural machinery hydraulic power units
Important: Verify mounting interface, shaft type, rotation, control configuration, and port locations match the existing BOBCAT 6675294 installation and system plumbing before installation.
Product Selection Guide
These Series 52/53 components share a 3600 PSI nominal pressure rating, so selection is mainly driven by displacement (flow needs) and allowable speed.
?? Important: The specifications shown are for reference and comparison purposes. Always verify specifications with the official manufacturer documentation or contact our technical team before ordering to ensure compatibility with your application.
| Part Number | Displacement | Pressure | Max Speed | Series |
|---|---|---|---|---|
| R986110939 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111159 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111098 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111479 | 28cc | 3600 PSI | 3000 | 52/53 |
| R986111389 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110939 is 71cc; comparable 71cc options (R986111098, R986111389) match the same displacement, while R986111159 increases displacement to 100cc for higher flow and R986111479 reduces displacement to 28cc for lower flow demand.
Pressure Rating
All listed comparison parts show 3600 PSI pressure, matching R986110939’s nominal pressure; for R986110939, also ensure your system requirements align with its 4600 PSI peak pressure capability.
Speed
R986110939 is rated to 2600 max speed; the 100cc option (R986111159) is lower at 2300, while the 28cc option (R986111479) is higher at 3000—choose based on your operating RPM limits.
Quick Selection Guide
Choose: R986110939
Because: When you need a 71cc unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: Choose R986111159 (100cc) when your required displacement/flow exceeds 71cc, noting its lower listed speed (2300) versus 2600.
Choose: Lower displacement model
Because: Choose R986111479 (28cc) when a smaller displacement is appropriate for reduced flow demand, and you need a higher listed speed capability (3000).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, pressure, and speed ratings align with your system requirements.
