Bosch Rexroth R986111123 (Series 31*) is a reliable OEM replacement for CAT 341-7664, built to deliver compatible fit and consistent hydraulic performance in demanding duty cycles.
Technical Specifications
Flow Performance
With a 110 cc displacement, the R986111123 provides predictable volumetric output per revolution for stable system response. Its performance is designed for consistent delivery across operating speeds up to 2200 RPM, supporting reliable machine function under load.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is engineered to maintain performance in high-pressure operating conditions. The 2200 RPM maximum speed capability supports dependable operation across a wide range of duty profiles while helping sustain consistent output over time.
Installation
Designed as a direct OEM replacement for CAT 341-7664, the R986111123 matches expected mounting and interface requirements for straightforward installation. It is intended to install without modifications when replacing the original component.
Features and Benefits
- 110 cc displacement: Delivers consistent, repeatable flow per revolution to support stable actuator and circuit behavior.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Handles high working pressures with defined headroom for transient peak events in demanding hydraulic cycles.
- 2200 RPM maximum speed rating: Supports reliable operation across higher-speed operating points while maintaining predictable output.
Operational Information
Operate within the stated limits of 3600 PSI nominal (4600 PSI peak) and up to 2200 RPM to maintain reliable performance. Normal operation should be supported by appropriate system fluid condition and temperature control consistent with standard hydraulic practice.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
These 31* components are best compared by matching displacement (flow per revolution) first, then confirming the same pressure rating and allowable speed for your duty cycle. If you’re comparing other piston pumps, start with the same approach to avoid mismatched flow and performance.
?? 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 |
|---|---|---|---|---|
| R986111123 | 110cc | 3600 PSI | 2200 | 31* |
| R986110970 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110083 | 110cc | 3600 PSI | 2200 | 31* |
| R986110090 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110581 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111123 and R986110083 are 110cc options for higher flow per revolution, while R986110970 (45cc) and the 71cc/74cc models (R986110090/R986110581) suit lower flow needs or finer control; choose displacement based on required flow at your available operating speed. If you’re evaluating other hydraulic pumps for the same machine, keep the same displacement-first comparison to maintain predictable system response.
Pressure Rating
All compared models list 3600 PSI nominal pressure, so selection is primarily driven by displacement and speed; for R986111123 specifically, also confirm your system stays within its 4600 PSI peak limit.
Speed
R986111123 (and R986110083) are rated to 2200 max speed, while the smaller-displacement alternatives listed are rated to 2600; if your prime mover speed is higher, a 2600-rated option may be a better match provided displacement meets flow needs.
Quick Selection Guide
Choose: R986111123
Because: When you need a 31* unit with 110cc displacement, 3600 PSI nominal pressure, 4600 PSI peak capability, and a 2200 max speed rating to match the existing installation requirements.
Choose: R986110083
Because: When you need the same 110cc displacement, 3600 PSI nominal pressure, and 2200 max speed as R986111123 for a close performance match within the 31* series.
Choose: R986110970 / R986110090 / R986110581
Because: When you need lower displacement (45cc, 71cc, or 74cc) and/or a higher 2600 max speed rating, and your required flow can be met with the smaller displacement at your operating speed.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, nominal pressure, peak pressure, and max speed align with your system requirements. If you’re cross-referencing adjacent options in this family, you may also want to review R986110076 for fit and performance comparison.
