Bosch Rexroth R986110115 (Series 52/53) is a direct OEM replacement for CAT 209-3258, delivering specified-fit compatibility with consistent 45 cc displacement performance for reliable hydraulic operation.
Technical Specifications
Flow Performance
With a 45 cc displacement, R986110115 provides predictable volumetric output per revolution to support stable actuator speed and controllable system response. The design is intended to maintain consistent flow characteristics across the operating range up to 2600 max speed. Performance is matched to OEM expectations for repeatable hydraulic behavior.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, the unit is built to sustain high-load hydraulic duty without exceeding stated limits. Operation up to 2600 max speed supports responsive performance while maintaining controlled mechanical loading. These ratings help maintain consistent output under pressure and speed demands typical of mobile and industrial hydraulic circuits.
Installation
Engineered as an OEM replacement for CAT 209-3258, R986110115 is intended as a direct-fit component with standard mounting and connection compatibility. Installation is designed to require no modifications when replacing the original unit.
Features and Benefits
- 45 cc displacement: Delivers consistent volume per revolution for repeatable flow output and predictable actuator response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high-pressure operation with defined nominal and peak limits for controlled performance under load.
- 2600 max speed rating: Enables operation at higher rotational speeds to maintain required hydraulic output within specified limits.
Operational Information
Operate within the stated limits of 3600 PSI nominal, 4600 PSI peak, and up to 2600 max speed to maintain expected reliability and output stability. Unit weight is 40, supporting standard handling and mounting practices for this component class.

Compatibility & Applications
Direct Replacement Information
This Bosch Rexroth R986110115 axial piston variable pump replaces CAT 209-3258 in high-pressure closed-loop and open-loop hydraulic pumps system applications.
- Hydraulic systems requiring 45cc displacement variable-flow control
- Circuits operating at 3600 PSI nominal pressure with up to 2600 max speed input
- Axial piston variable pump duties for hydrostatic drive loops, implement hydraulics, and auxiliary pump circuits
Common Applications
This Bosch Rexroth R986110115 is commonly used in:
- construction and earthmoving equipment
- mining and quarry equipment
- material handling equipment
- industrial mobile hydraulics (power units and auxiliary circuits)
Important: Verify mounting interface, shaft type, rotation, control configuration, and port locations match the existing CAT 209-3258 installation before use.
Product Selection Guide
These Series 52/53 components share a 3600 PSI nominal pressure rating, so selection typically comes down to matching displacement (flow) and confirming the required maximum speed capability for piston pumps.
?? 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 |
|---|---|---|---|---|
| R986110115 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111125 | 85cc | 3600 PSI | 2500 | 52/53 |
| R986110038 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110056 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110070 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110115 and R986110070 are 45cc options for lower flow demand, while R986110038 (71cc), R986110056 (74cc), and R986111125 (85cc) increase displacement for higher flow requirements within the same series.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986110115 also specifies a 4600 PSI peak pressure requirement to match, so verify peak pressure needs if your system relies on transient pressure capability.
Speed
Maximum speed is 2600 on R986110115, R986110038, R986110056, and R986110070, while R986111125 is listed at 2500, which may matter in high-RPM duty where full speed capability is required.
Quick Selection Guide
Choose: R986110115
Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: Choose R986110038 (71cc), R986110056 (74cc), or R986111125 (85cc) when flow requirements exceed a 45cc displacement option, while maintaining a 3600 PSI nominal pressure rating.
Choose: Lower pressure model
Because: Not applicable within this comparison set, as all listed alternatives are rated at 3600 PSI nominal pressure.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you are cross-referencing outside the CAT 209-3258 application, related Rexroth options such as R986111250 may be a better fit depending on displacement, controls, and mounting.
