Bosch Rexroth R986110630 (Series 52/53) is an OEM replacement for CAT 365-2143, engineered for reliable, direct-fit hydraulic performance with full compatibility in the original installation envelope.
Technical Specifications
Flow Performance
With a 100 cc displacement, the R986110630 delivers consistent, predictable flow output per revolution for stable actuator response and controllability. Performance is designed to remain steady across operating conditions up to a maximum speed of 2300 rpm, supporting responsive system behavior. The Series 52/53 design targets efficient power transfer by maintaining controlled flow characteristics under load.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is built to sustain performance in high-load hydraulic circuits. The pressure capability supports strong torque and output stability while maintaining operating efficiency under demanding duty cycles. Maximum speed of 2300 rpm helps preserve performance over a wide operating range without exceeding the component’s design limits.
Installation
Designed as a direct OEM replacement for CAT 365-2143, the R986110630 matches the intended fit and interface for straightforward installation. It is intended to install without modifications when replacing the original component.
Features and Benefits
- 100 cc displacement: Provides repeatable flow per revolution for consistent machine response and controllable hydraulic output.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high-load operation with pressure headroom for transient spikes while maintaining stable output.
- 2300 rpm maximum speed rating: Enables responsive performance across higher operating speeds while staying within rated limits.
Operational Information
Operate within the stated limits of 3600 PSI nominal, 4600 PSI peak, and up to 2300 rpm to maintain reliable performance. Component mass is 75 (as specified), supporting stable installation in the intended mounting location and operating environment.
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 class, so selection typically comes down to matching displacement (flow per revolution) and allowable operating speed to your existing system requirements. If you’re comparing other hydraulic pumps, confirm the control type and mounting/shaft standards match your machine.
?? 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 |
|---|---|---|---|---|
| R986110630 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110064 | 60cc | 3600 PSI | N/A | 52 |
| R986111247 | 110cc | 3600 PSI | 2200 | 31* |
| R986110057 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111581 | 60cc | 3600 PSI | 2600 | 52 |
Key Differences
Displacement
R986110630 is 100cc, while the alternatives range from 60cc and 74cc up to 110cc; higher displacement supports higher flow at the same speed, while lower displacement can better match lower-flow systems or reduce flow without changing drive speed.
Pressure Rating
All listed comparison parts show 3600 PSI pressure, matching the nominal pressure of R986110630; confirm your application also accounts for the current part’s 4600 PSI peak requirement if peak events are present.
Speed
Maximum speed varies where provided: R986110630 is 2300, compared to 2200 (R986111247) and 2600 (R986110057 and R986111581); choose a model that meets or exceeds your required operating speed.
Quick Selection Guide
Choose: R986110630
Because: When you need a 100cc displacement unit with 3600 PSI nominal / 4600 PSI peak capability and a maximum speed of 2300.
Choose: Higher displacement model
Because: Choose R986111247 (110cc) when your flow requirement is higher than a 100cc unit can provide at the same drive speed, while staying in the 3600 PSI nominal pressure class (max speed shown as 2200).
Choose: Lower pressure model
Because: None of the listed comparison parts are rated below 3600 PSI nominal, so a lower-pressure selection cannot be made from this set; if your system operates at lower pressures, verify an alternative part number with an appropriately lower pressure rating.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. For more options in the same family of piston pumps, compare displacement, controls, and allowable speed with your current setup.
For application-specific guidance, contact our technical team. If you’re evaluating alternate Rexroth part numbers for AGCO cross references, you may also want to review R986111250 as another comparison point.
