Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, this unit is built to sustain performance under high-load hydraulic conditions. The Series 52/53 design supports dependable operation up to 2300 rpm, helping maintain output stability over extended run time.
Installation
Designed as an OEM-form direct replacement for CAT 397-3967, the R986110685 installs with standard mounting interfaces and matched connection points. It is intended to replace the original component without modifications.
Features and Benefits
- 100 cc displacement: Delivers consistent volumetric output per revolution for predictable machine response.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports high-load operation and manages short-duration pressure spikes without immediate performance loss.
- 2300 rpm maximum speed capability: Maintains stable operation at higher shaft speeds to support responsive hydraulic performance.
Operational Information
Operate within the stated limits of 3600 PSI nominal pressure (4600 PSI peak) and up to 2300 rpm to maintain consistent performance. The 75 lb assembly is suited for demanding hydraulic environments where stable output and repeatable operation are required.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
These 52/53 series components share the same nominal pressure rating, with selection primarily driven by required displacement (flow) and allowable operating 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 |
|---|---|---|---|---|
| R986110685 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110941 | 63cc | 3600 PSI | 2600 | 53 |
| R986110125 | 28cc | 3600 PSI | 3000 | 52/53 |
| R986110077 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110043 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110685 is 100cc for higher flow per revolution, while the comparison parts are lower displacement options (63cc, 45cc, and 28cc) suited to lower flow requirements or finer control at a given speed.
Pressure Rating
All listed comparison parts show 3600 PSI pressure rating, matching R986110685’s nominal pressure; confirm whether your duty cycle requires the 4600 PSI peak capability specified for R986110685.
Speed
R986110685 is rated to 2300 max speed, while the similar products list higher max speeds (2600–3000), which may be beneficial if your system requires higher RPM operation with appropriate displacement.
Quick Selection Guide
Choose: R986110685
Because: When you need 100cc displacement with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and operation up to 2300 max speed.
Choose: Higher displacement model
Because: When flow requirements exceed what a 100cc displacement can provide at your available operating speed. If your application calls for a different frame/displacement range, our team can also help compare alternatives like R986111250.
Choose: Lower pressure model
Because: When system operates at lower pressures for cost savings.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, pressure (nominal/peak), and maximum speed align with your system requirements.
