Bosch Rexroth R986111159 (Series 52/53) is a direct OEM replacement for CAT 196-7765, built to deliver consistent hydraulic performance with reliable, drop-in compatibility.
Technical Specifications
Flow Performance
With a 100 cc displacement, the R986111159 provides predictable volumetric output per revolution for stable system response. It supports operation up to 2300 max speed, enabling strong flow capability across the operating range when paired with appropriate prime mover speed control. Performance is matched to OEM expectations for consistent actuation and cycle repeatability.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak pressure capability, this unit is designed to maintain performance under demanding load conditions. The Series 52/53 design supports sustained operation at elevated pressures while maintaining stable output characteristics. Operation up to 2300 max speed helps maintain throughput without exceeding rated limits.
Installation
Designed as an OEM replacement for CAT 196-7765, the R986111159 is intended for direct fit installation with no modifications. Mounting and interface compatibility are aligned to support straightforward changeout in existing systems.
Features and Benefits
- 100 cc displacement: Delivers consistent volume per revolution for predictable actuator speed and repeatable machine cycles.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Handles high working pressures with defined peak capacity to support transient load events without exceeding rated limits.
- 2300 max speed capability: Supports higher rotational speeds to maintain required flow output and system responsiveness within specified operating limits.
Operational Information
Operate within the specified 3600 PSI nominal and 4600 PSI peak pressure limits and do not exceed 2300 max speed to maintain stable performance. Suitable for hydraulic systems requiring consistent output under high-pressure duty cycles when operated within the component’s rated conditions.
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, so selection typically comes down to matching displacement (flow needs) and allowable speed limits for your duty cycle.
?? 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 |
|---|---|---|---|---|
| R986111159 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111618 | 85cc | 3600 PSI | 2500 | 52/53 |
| R986111315 | 60cc | 3600 PSI | 2600 | 52 |

| R986110090 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111159 is the highest displacement option listed (100cc) for higher flow per revolution; the alternatives (85cc, 71cc, 60cc, 45cc) reduce flow output and can be better fits when the system is oversized or when you need finer control at a given speed.
Pressure Rating
All compared models list 3600 PSI pressure, so pressure capability is not a differentiator among these options; ensure your system requirements also account for peak pressure needs where applicable.
Speed
Maximum speed varies: R986111159 is rated to 2300, while the alternatives list 2500 or 2600, which may be preferable if your application requires higher operating speed within the same nominal pressure class.
Quick Selection Guide
Choose: R986111159
Because: When you need 100cc displacement with 3600 PSI nominal pressure and operation up to 2300 max speed, and you must maintain Series 52/53 fit and performance.
Choose: R986111618
Because: When you want to stay at 3600 PSI nominal pressure but reduce displacement to 85cc and need a higher max speed rating (2500) than R986111159.
Choose: R986110090, R986111315, or R986110944
Because: When your system can use lower displacement (71cc, 60cc, or 45cc) while maintaining 3600 PSI nominal pressure, and you want the higher max speed rating shown for these options (2600).
Compatibility: Verify mounting pattern, shaft configuration, port sizes, and the required displacement/pressure/speed ratings match your existing installation and operating conditions (including peak pressure). If you’re comparing other piston pumps, confirm the same interface details before substituting.
