Bosch Rexroth R986110036 (Series 52/53) is an OEM replacement for CAT 152-7768, engineered for direct-fit compatibility and consistent hydraulic performance in demanding duty cycles.
Technical Specifications
Flow Performance
With a 45 cc displacement, the R986110036 delivers predictable volumetric output per revolution for stable actuator and motor control. Flow scales linearly with speed up to 2600 max RPM, supporting repeatable machine response across the operating range.
Efficiency & Durability
The component is rated for 3600 PSI nominal pressure with 4600 PSI peak capability to maintain performance under transient load conditions. Continuous operation up to 2600 RPM supports sustained duty cycles while preserving controlled output under rated pressures.
Installation
Designed as a direct OEM replacement for CAT 152-7768, the R986110036 installs with standard mounting interfaces for Series 52/53 fitment. It is intended to replace the original unit without modifications when installed to OEM service practices.
Features and Benefits
- 45 cc displacement: Provides consistent displacement per revolution for predictable flow output and repeatable hydraulic response.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports high-load operation with headroom for short-duration pressure spikes without requiring derating at nominal conditions.
- 2600 max RPM capability: Enables stable flow delivery across a wide operating speed range, supporting responsive control at higher shaft speeds.
Operational Information
Operate within the stated 3600 PSI nominal and 4600 PSI peak limits and up to 2600 RPM to maintain expected performance. The 40 lb unit is suited for installations where mass and mounting rigidity support stable operation under rated hydraulic loads.
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 class, so selection is primarily driven by displacement (flow needs) and allowable speed 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 |
|---|---|---|---|---|
| R986110036 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111115 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110039 | 63cc | 3600 PSI | 2600 | 53 |
| R986111651 | 60cc | 3600 PSI | 2600 | 52 |
| R986110073 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110036 is 45cc for lower flow demand; the comparison options increase displacement to 60cc (R986111651), 63cc (R986110039), 71cc (R986110073), and 100cc (R986111115) when higher flow per revolution is required.
Pressure Rating
All listed comparison products show 3600 PSI nominal pressure, matching the current product’s nominal rating; R986110036 also specifies a 4600 PSI peak rating, which should be confirmed against your system’s peak pressure requirements.
Speed
R986110036 is rated to 2600 max speed, matching the 60cc/63cc/71cc options at 2600; the 100cc option (R986111115) lists 2300, which may be a limiter if your application requires higher RPM.
Quick Selection Guide
Choose: R986110036
Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: When flow requirements exceed a 45cc displacement—consider 60cc (R986111651), 63cc (R986110039), 71cc (R986110073), or 100cc (R986111115) while ensuring the listed max speed (notably 2300 on the 100cc option) fits your RPM needs.
Choose: Lower pressure model
Because: When system operates at lower pressures for cost savings.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm both nominal and peak pressure requirements align with the selected unit. If you’re standardizing across multiple hydraulic pumps in a fleet, matching control type and shaft rotation is especially important.

Compatibility & Applications
Direct Replacement Information
This Bosch Rexroth R986110036 replaces CAT 152-7768 in hydraulic power unit and mobile equipment pump applications.
- Closed- and open-loop hydraulic systems requiring 45cc displacement variable flow control
- Circuits operating at 3600 PSI nominal pressure (up to system relief settings as applicable)
- Axial piston variable pump circuits for load-sensing, pressure-compensated, and proportional control functions
- High-speed pump applications up to 2600 RPM where variable displacement is used for efficiency and heat reduction
Common Applications
This Bosch Rexroth R986110036 is commonly used in:
- construction and earthmoving equipment hydraulics
- material handling equipment (forklifts, telehandlers, reach stackers)
- industrial hydraulic power units and production machinery
- agricultural and forestry equipment hydraulic systems
For related options in the same family of piston pumps, compare displacement and control configuration to match your duty cycle and available drive speed.
Important: Confirm mounting interface, shaft type, rotation, control configuration, and porting match the existing CAT 152-7768 installation before installation. If you’re considering an alternate cross-reference such as R986111250, verify the control and mounting details against your current setup.
