Technical Specifications
Flow Performance
With a 71 cc displacement, the R986110631 delivers predictable per-revolution output for stable hydraulic response across operating speeds. Its design supports strong flow performance up to 2600 max speed, helping maintain consistent actuator and circuit behavior under load.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak pressure capability, this component is built to sustain performance through high-load operating cycles. Stable operation up to 2600 max speed helps maintain efficiency and response consistency without sacrificing durability.
Installation
Configured as a direct OEM replacement for CAT 365-2142, the R986110631 is intended to match the existing mounting and interface requirements. It installs as an OEM-fit replacement without modifications when replacing the specified part number.
Features and Benefits
- 71 cc displacement: Delivers consistent per-revolution output to support predictable hydraulic response and repeatable machine performance.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Handles high working pressures and short-duration pressure spikes to maintain performance under heavy loads.
- 2600 max speed capability: Supports high-speed operation to sustain flow output and responsive control where higher operating speeds are required.
Operational Information
Designed for reliable operation in high-pressure hydraulic systems up to 3600 PSI nominal and 4600 PSI peak, with speed capability up to 2600. For best reliability, operate within the machine’s established hydraulic fluid and temperature limits for the CAT 365-2142 replacement position.
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 the same nominal pressure rating (3600 PSI), so selection typically comes down to matching displacement (flow) and allowable speed to your existing system requirements within your broader hydraulic pumps strategy.
?? 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 |
|---|---|---|---|---|
| R986110631 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110679 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111454 | 280cc | 3600 PSI | N/A | 52/53 |
| R986111070 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110610 | 60cc | 3600 PSI | 2600 | 52 |
Key Differences
Displacement
R986110631 is 71cc, sitting between lower-displacement options (45cc R986111070, 60cc R986110610) and higher-displacement options (100cc R986110679, 280cc R986111454); choose higher displacement when you need more flow per revolution, and lower displacement when you want reduced flow or finer control at a given speed.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986110631 additionally specifies a 4600 PSI peak pressure, so confirm your system’s required peak events align with the part you select.
Speed
R986110631 supports 2600 max speed, matching the 45cc and 60cc options (both 2600), while the 100cc option is lower at 2300; verify the required operating speed does not exceed the selected part’s limit (speed is not provided for R986111454).
Quick Selection Guide
Choose: R986110631
Because: When you need a 71cc displacement Series 52/53 unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2600 max speed.
Choose: Higher displacement model
Because: Choose R986110679 (100cc) or R986111454 (280cc) when your required displacement (flow per revolution) is higher than 71cc while maintaining a 3600 PSI nominal pressure rating.
Choose: Lower pressure model
Because: No lower nominal pressure alternatives are provided in this comparison set; all listed options are 3600 PSI nominal, so select based on displacement and speed instead.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation.
