Bosch Rexroth R986110066 is a Series 52/53 hydraulic unit engineered as an OEM replacement for CAT 184-3124, delivering reliable performance with direct compatibility and consistent output.
Technical Specifications
Flow Performance
With a 45 cc displacement, the R986110066 provides predictable volumetric output per revolution for stable hydraulic response. It is rated up to 2600 rpm, supporting high-speed operation where consistent flow delivery is required. The Series 52/53 design is intended to maintain repeatable performance under demanding duty cycles.
Efficiency & Durability
Nominal pressure is rated at 3600 psi with peak capability up to 4600 psi, supporting high-load operation without sacrificing control stability. Maximum speed is 2600 rpm to sustain performance across a wide operating range. The 40 lb assembly supports robust installation in mobile and industrial hydraulic systems where mechanical integrity is required.
Installation
Designed as a direct OEM replacement for CAT 184-3124, the R986110066 matches Series 52/53 fitment for straightforward installation. Intended to install without modifications when replacing the specified OEM component.
Features and Benefits
- 45 cc displacement: Delivers consistent volumetric output per revolution for predictable system response.
- 3600 psi nominal / 4600 psi peak pressure rating: Supports sustained high-load operation with headroom for transient pressure spikes.
- 2600 rpm maximum speed: Enables high-speed operation to maintain required flow delivery at elevated rotational speeds.
Operational Information
Operate within the stated limits of 3600 psi nominal, 4600 psi peak, and up to 2600 rpm to maintain stable output and service life. Performance is intended to remain consistent under continuous hydraulic duty where controlled flow and pressure capability are required.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Compatibility & Applications
Direct Replacement Information
This Bosch Rexroth R986110066 replaces CAT 184-3124 in axial piston variable pump hydraulic system applications.
- Closed-loop or open-loop hydraulic systems requiring 45cc displacement variable flow control
- Circuits operating at 3600 PSI nominal pressure (high-pressure mobile/industrial hydraulics)
- Pump supply for hydrostatic drive, implement, and auxiliary hydraulic circuits up to 2600 max speed
Common Applications
This Bosch Rexroth R986110066 is commonly used in:
- construction and earthmoving equipment hydraulic systems
- material handling equipment (lift/steer/auxiliary hydraulics)
- industrial power units and machine hydraulics
Important: Verify mounting pattern, shaft type, rotation, control configuration, and port locations match the existing CAT 184-3124 installation.
Product Selection Guide
These Series 52/53 components share the same nominal pressure class (3600 PSI) but vary mainly by displacement and, in some cases, maximum speed, which impacts flow capability and operating range. If you’re comparing other hydraulic pumps for your system, use displacement and speed as your primary sizing checks before confirming controls and mounting details.
?? 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 |
|---|---|---|---|---|
| R986110066 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110672 | 60cc | 3600 PSI | 2600 | 52 |
| R986110085 | 140cc | 3600 PSI | 2000 | 31* |
| R986111529 | 163cc | 3600 PSI | N/A | 52/53 |
| R986110100 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110066 is 45cc, while the comparison parts range from 60cc (R986110672) to 163cc (R986111529); higher displacement is typically selected when more flow is needed at a given speed, while 45cc fits lower-flow requirements.
Pressure Rating
All listed comparison models show 3600 PSI pressure, matching the nominal pressure of R986110066; R986110066 also lists a 4600 PSI peak pressure, so confirm peak-pressure needs when substituting.
Speed
R986110066 is rated to 2600 max speed, matching R986110672 and R986110100 (2600), while R986110085 is lower at 2000 and R986111529 is not specified; choose based on your required operating speed range.
Quick Selection Guide
Choose: R986110066
Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure, and up to 2600 max speed in a Series 52/53 configuration.
Choose: Higher displacement model
Because: When flow requirements exceed what a 45cc unit can provide, consider 60cc (R986110672), 71cc (R986110100), 140cc (R986110085), or 163cc (R986111529), while also confirming any speed limits (e.g., 2000 max speed on R986110085). For more options in this pump style, browse our piston pumps selection.
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. If you’re cross-referencing a different OEM build, related Rexroth options such as R986111250 may be a better starting point depending on displacement, controls, and mounting requirements.
