Bosch Rexroth R986110771 (Series 52/53) is a direct OEM replacement for CAT 341-7659, engineered for reliable hydraulic performance and fit compatibility in demanding duty cycles.
Technical Specifications
Flow Performance
With a 45 cc displacement, the unit delivers consistent volumetric output per revolution to support stable system flow characteristics across operating speeds. Performance is maintained up to a maximum speed of 2600 RPM, supporting repeatable response under varying load conditions.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, the component is designed to sustain high-pressure operation while maintaining controlled output. The 2600 RPM maximum speed capability supports continuous operation within specified limits, helping preserve performance under sustained cycling.
Installation
Designed as a direct replacement for CAT 341-7659, the R986110771 installs with OEM-intended fit and interface alignment. It is intended to replace the original unit without requiring modifications.
Features and Benefits
- 45 cc displacement: Provides a fixed, repeatable displacement per revolution to support consistent system flow output.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports high-pressure operation with defined headroom for transient peak pressure events.
- 2600 RPM maximum speed capability: Enables operation at higher rotational speeds while maintaining controlled hydraulic output within specified limits.
Operational Information
Operate within the stated 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2600 RPM maximum speed to maintain expected reliability. The component’s 40 lb build supports stable installation and handling in typical hydraulic service conditions.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
These Series 52/53 components share a 3600 PSI nominal pressure rating, so selection is primarily driven by displacement (flow) and maximum speed requirements.
?? 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 |
|---|---|---|---|---|
| R986110771 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111204 | 140cc | 3600 PSI | 2000 | 31* |
| R986110072 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110119 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111581 | 60cc | 3600 PSI | 2600 | 52 |
Key Differences
Displacement
R986110771 is 45cc, while the comparison options range from 60cc to 140cc; higher displacement is typically chosen when you need more flow at a given speed, and lower displacement when you need less flow or finer control within the same series.
Pressure Rating
All listed comparison models show 3600 PSI nominal pressure, matching R986110771; however, R986110771 also lists a 4600 PSI peak pressure, so confirm peak-pressure requirements when substituting.
Speed
R986110771 is rated to 2600 max speed; most alternatives listed are also 2600, except R986111204 at 2000, which may be limiting if your application requires higher operating speed.
Quick Selection Guide
Choose: R986110771
Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure, and up to 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: When your required displacement (flow) is higher than 45cc—e.g., consider 60cc (R986111581), 71cc (R986110119), 74cc (R986110072), or 140cc (R986111204) while ensuring the speed rating meets your needs.
Choose: Lower pressure model
Because: When the system operates at lower pressures; verify the replacement’s nominal and peak pressure ratings match your requirements (no lower-pressure alternatives are provided in this comparison list).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, nominal/peak pressure, and maximum speed align with your system requirements.
