Compatibility & Applications
Direct Replacement Information
This Rexroth R986110971 replaces CAT 318-2595 in heavy-duty mobile hydraulic system applications.
- Closed-loop or open-circuit hydrostatic systems requiring 74cc displacement
- Circuits operating at 3600 PSI nominal pressure with variable flow/pressure control
- Primary implement and auxiliary hydraulic circuits where pump speed can reach up to 2600 RPM
Common Applications
This Bosch Rexroth R986110971 is commonly used in:
- construction and earthmoving equipment hydraulic pumps systems
- excavator implement and auxiliary hydraulics
- industrial power units and test stands using axial piston variable pumps
Important: Verify mounting interface, shaft type, control configuration, rotation, and port locations match the existing CAT 318-2595 installation.
Product Selection Guide
These Series 52/53 parts are best compared by matching displacement first (flow per revolution) and then confirming pressure and speed ratings align with your existing setup. If you’re comparing across product families, browse our piston pumps selection for similar axial piston options.
?? 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 |
|---|---|---|---|---|
| R986110971 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110061 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110632 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110052 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110062 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110971, R986110061, and R986110632 are all 74cc options for the same nominal flow per revolution, while R986110062 (71cc) and R986110052 (45cc) reduce flow per revolution—use lower displacement when you need less flow or finer control at a given speed.
Pressure Rating
All listed comparison parts show 3600 PSI pressure, matching R986110971’s nominal pressure; however, R986110971 also specifies a 4600 PSI peak pressure requirement—confirm any replacement supports your system’s peak pressure events.
Speed
All compared models list 2600 speed, matching R986110971’s max speed, so selection is primarily driven by displacement and ensuring pressure capability matches both nominal and peak requirements.
Quick Selection Guide
Choose: R986110971
Because: When you need a Series 52/53 74cc unit rated for 3600 PSI nominal with a specified 4600 PSI peak and 2600 max speed.
Choose: R986110061 or R986110632
Because: When you want to stay at 74cc displacement with 3600 PSI and 2600 speed to match the same core flow and operating envelope as the current 74cc configuration.
Choose: R986110062 or R986110052
Because: When a lower displacement (71cc or 45cc) is acceptable or preferred to reduce flow per revolution while keeping the listed 3600 PSI pressure and 2600 speed ratings.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm the replacement meets both nominal and peak pressure requirements for your system. For other Rexroth replacement options in similar duty cycles, see R986111250.
