Bosch Rexroth R986111014 (Series 31*) is a reliable OEM replacement for CAT 373-6629, engineered for direct compatibility while maintaining consistent hydraulic performance under demanding duty cycles.
Technical Specifications
Flow Performance
With a 110 cc displacement, the R986111014 delivers predictable, repeatable flow output per revolution to support stable machine response. Its Series 31* design is intended for consistent performance across operating conditions where dependable hydraulic delivery is required.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is built to sustain performance under high-load events without compromising operational stability. A maximum speed of 2200 supports reliable operation across a broad working range while maintaining controlled hydraulic output.
Installation
Designed as a direct OEM replacement for CAT 373-6629, the R986111014 installs as an OEM-fit component with no modifications required. Maintain standard mounting and connection practices to preserve intended alignment and hydraulic integrity.
Features and Benefits
- 110 cc displacement: Provides consistent volume per revolution for predictable actuator response and stable machine control.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports continuous high-pressure operation and tolerates short peak-load events for reliable performance under demanding cycles.
- 2200 max speed (Series 31*): Enables dependable operation at higher rotational speeds while maintaining consistent hydraulic output characteristics.
Operational Information
Operate within rated limits of 3600 PSI nominal, 4600 PSI peak, and up to 2200 speed to support long-term reliability. The 88 lb assembly is suited for stable mounting in OEM-equivalent hydraulic layouts where consistent performance is expected.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
These 31* components share the same nominal pressure rating, so selection typically comes down to matching displacement and allowable speed to your system’s flow and RPM requirements. If you’re comparing options across our broader hydraulic pumps lineup, keep the same selection logic in mind.
?? 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 |
|---|---|---|---|---|
| R986111014 | 110cc | 3600 PSI | 2200 | 31* |
| R986110941 | 63cc | 3600 PSI | 2600 | 53 |

Key Differences
Displacement
R986111014 is the highest displacement option listed at 110cc, while the comparison parts range from 45cc to 85cc; higher displacement is typically chosen when you need more flow per revolution, and lower displacement when you need less flow or finer control at a given speed.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986111014 additionally specifies a 4600 PSI peak pressure, which may matter if your duty cycle includes pressure spikes and the system is designed to accommodate them.
Speed
Maximum speed varies across the list: R986111014 is rated to 2200 max speed, while the other options shown are rated between 2500 and 2600; choose a model whose max speed meets or exceeds your operating RPM.
Quick Selection Guide
Choose: R986111014
Because: When you need 110cc displacement with 3600 PSI nominal pressure and have operating speed requirements up to 2200 max speed (with a specified 4600 PSI peak pressure).
Choose: Higher displacement model
Because: When required displacement (flow per revolution) exceeds 110cc; none of the similar products listed exceed 110cc, so a different part outside this set would be needed.
Choose: Lower pressure model
Because: When your system operates below 3600 PSI nominal; no lower-nominal-pressure options are provided in this comparison set, so confirm pressure requirements and select an appropriate part outside this group if needed.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re sourcing related piston pumps, confirm control type and porting style as well.
