Bosch Rexroth R986110100 (Series 52/53) is an OEM replacement for CAT 134-2947, built to deliver compatible fit and consistent hydraulic performance in demanding duty cycles.
Technical Specifications
Flow Performance
With a 71 cc displacement, the R986110100 is designed to provide predictable output per revolution for stable actuator and implement response. It supports high-flow operation at speeds up to 2600 RPM, helping maintain consistent system behavior across the operating range.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is suited for high-load hydraulic circuits while maintaining controlled performance under pressure. The 2600 RPM maximum speed supports sustained operation without sacrificing responsiveness in systems that require both pressure and speed capability.
Installation
Engineered as a direct OEM replacement for CAT 134-2947, the R986110100 is intended to match the original interface for straightforward installation. It is designed to fit without modifications when replacing the specified OEM component.
Features and Benefits
- 71 cc displacement: Delivers consistent displacement per revolution for repeatable flow output and predictable machine response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high working pressures with overhead for transient spikes to help maintain performance under load.
- 2600 RPM maximum speed: Enables high-flow operation at elevated shaft speeds to support fast cycle times where system design allows.
Operational Information
Designed for hydraulic systems operating up to 3600 PSI nominal with intermittent peaks to 4600 PSI and shaft speeds up to 2600 RPM. The 48.5 lb build supports stable operation in demanding environments where consistent output and controlled performance are required.
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 are best compared by matching displacement for flow needs while confirming pressure and speed limits align with your system requirements. If you’re evaluating alternative hydraulic pumps, match the control type and porting to avoid installation changes.
?? 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 |
|---|---|---|---|---|
| R986110100 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110038 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110079 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110116 | 28cc | 3600 PSI | 3000 | 52/53 |
| R986111616 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986110100 and R986110038 are 71cc options for matching the same displacement, while 100cc models (R986110079, R986111616) suit higher flow requirements and the 28cc model (R986110116) fits lower flow needs where a smaller displacement is required.
Pressure Rating
All listed comparison parts show 3600 PSI pressure rating, matching the nominal pressure of R986110100; confirm your system does not exceed the 4600 PSI peak rating of the current unit.
Speed
R986110100 and R986110038 match at 2600 max speed, 100cc options (R986110079, R986111616) list 2300 max speed, and the 28cc option (R986110116) lists 3000 max speed—choose based on the maximum operating speed required.
Quick Selection Guide
Choose: R986110100
Because: When you need a Series 52/53 unit with 71cc displacement, 3600 PSI nominal pressure, 4600 PSI peak pressure, and 2600 max speed to match the current installation requirements.
Choose: Higher displacement model
Because: When flow requirements exceed a 71cc displacement, consider the 100cc options (R986110079 or R986111616) while ensuring the lower listed max speed (2300) is acceptable.
Choose: Lower pressure model
Because: Not applicable here because the compared models provided all list 3600 PSI pressure rating; select based on displacement and speed instead.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. For other piston pumps in this family, confirm rotation and compensator/control options before substituting.
