Bosch Rexroth R986110040 (Series 52/53) is a direct OEM replacement for CAT 224-4430, delivering matched fit and consistent hydraulic performance for reliable operation.
Technical Specifications
Flow Performance
With a 71 cc displacement, the R986110040 provides predictable output per revolution for stable actuator response and smooth machine control. Performance is maintained across operating speeds up to 2600 RPM, supporting consistent flow delivery within the component’s rated operating envelope.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with a 4600 PSI peak capability, this unit is built to sustain performance under high-load hydraulic demands. The Series 52/53 design supports dependable operation up to 2600 RPM, helping maintain output stability under varying duty cycles while managing pressure-driven stress.
Installation
Designed as an OEM-equivalent replacement for CAT 224-4430, the R986110040 is intended to install as a direct fit with no modifications. Use standard mounting and connection practices consistent with the original configuration.
Features and Benefits
- 71 cc displacement: Delivers consistent volume per revolution for predictable hydraulic response and controllable machine motion.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports high-load operation with headroom for transient pressure spikes within the rated limits.
- 2600 RPM maximum speed: Maintains stable performance at higher operating speeds for responsive system behavior.
Operational Information
Operate within the rated limits of 3600 PSI nominal pressure (4600 PSI peak) and speeds up to 2600 RPM to maintain consistent performance. With a 48.5 weight and Series 52/53 build, it is suited for demanding hydraulic duty where predictable output is required.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Important: Verify mounting pattern, shaft type, rotation, control configuration, and porting match the existing CAT 224-4430 installation before installation.
Product Selection Guide
These Series 52/53 components are best compared by matching displacement, pressure rating, and allowable speed to your existing system requirements. If you’re evaluating alternatives within our broader hydraulic pumps lineup, focus on the same core performance targets.
?? 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 |
|---|---|---|---|---|
| R986110040 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111185 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111171 | 60cc | 3600 PSI | 2600 | 52 |
| R986111358 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111098 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110040 is 71cc, matching R986111185 and R986111098 for like-for-like flow capability; R986111171 at 60cc is suited when slightly lower flow is acceptable, while R986111358 at 100cc is intended for higher flow demand.
Pressure Rating
All listed comparison models show 3600 PSI nominal pressure; select based on whether your system requires a 3600 PSI nominal rating and confirm any peak-pressure requirements against the current unit’s 4600 PSI peak specification.
Speed
R986110040 and the 71cc/60cc comparison options list 2600 max speed, while the 100cc option (R986111358) lists 2300, which may matter if your application runs near maximum RPM.
Quick Selection Guide
Choose: R986110040
Because: When you need a Series 52/53 replacement with 71cc displacement, 3600 PSI nominal pressure, and 2600 max speed to match the current unit’s core performance targets.
Choose: Higher displacement model
Because: When flow requirements exceed a 71cc displacement and your system can accommodate the speed limit shown for the higher-displacement option (e.g., the 100cc model lists 2300 max speed).
Choose: Lower displacement model
Because: When your system can operate with reduced flow (e.g., 60cc) while maintaining the same listed nominal pressure and speed rating. You can also compare similar piston pumps by displacement and control type to narrow options.
Compatibility: Verify mounting pattern, shaft configuration, port sizes, and that nominal/peak pressure and maximum speed requirements match your existing installation.
