Bosch Rexroth R986111054 (Series 52/53) is a reliable OEM replacement for CAT 340-6184, built to deliver consistent hydraulic performance with direct-fit compatibility.
Technical Specifications
Flow Performance
With a 74 cc displacement, the R986111054 provides predictable flow output per revolution for stable actuator and circuit response. Its Series 52/53 design supports consistent performance across operating speeds up to 2600, helping maintain repeatable machine behavior. The result is dependable flow delivery suited to systems that require steady, controllable hydraulic output.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is built to maintain performance under sustained load and transient pressure events. Operation up to 2600 max speed supports reliable output across varying duty cycles without sacrificing stability. These ratings help reduce performance drift and support long service life in demanding hydraulic environments.
Installation
Designed as a direct OEM replacement for CAT 340-6184, the R986111054 installs with OEM-fit compatibility and requires no modifications. Standard mounting and connection interfaces support straightforward integration into existing hydraulic assemblies.
Features and Benefits
- 74 cc displacement: Delivers consistent flow per revolution for predictable system response and repeatable motion control.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Maintains reliable operation under continuous working loads and short-duration pressure spikes.
- 2600 max speed (Series 52/53): Supports stable performance across higher operating speeds to match demanding duty cycles.
Operational Information
Engineered for reliable operation in hydraulic systems running up to 3600 PSI nominal (4600 PSI peak) and speeds up to 2600. For best reliability, operate within the machine’s established hydraulic fluid cleanliness and temperature controls.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Compatibility & Applications
Direct Replacement Information
This Rexroth R986111054 replaces CAT 340-6184 in closed-loop and open-circuit mobile hydraulic pump applications.
- Hydrostatic drive systems requiring 74cc displacement variable flow control
- Circuits operating at 3600 PSI nominal pressure with high-load duty cycles
- Mobile hydraulic systems up to 2600 RPM maximum pump speed for propulsion and implement functions
Common Applications
This Bosch Rexroth R986111054 is commonly used in:
- construction equipment (track drives, wheel drives, and implement hydraulics)
- mining equipment (drives and auxiliary hydraulic circuits)
- forestry machinery (harvester head and drive functions)
Important: Verify mounting interface, shaft configuration, rotation, and porting match the existing CAT 340-6184 installation before ordering. If you’re sourcing related hydraulic pumps, confirm the system type (open circuit vs. closed loop) and control options as part of the replacement process.
Product Selection Guide
These Series 52/53 components share a 3600 PSI nominal pressure rating, so selection typically comes down to matching displacement (flow) and any speed limits to your existing R986111054 setup. For broader options, compare similar piston pumps by displacement and control configuration.
?? 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 |
|---|---|---|---|---|
| R986111054 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111159 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110938 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110608 | 60cc | 3600 PSI | 2600 | 52 |
| R986110971 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111054 is 74cc; R986111159 is higher at 100cc for greater flow per revolution, while R986110608 is lower at 60cc for reduced flow—choose based on required output without changing operating speed.
Pressure Rating
All listed comparison models are rated at 3600 PSI nominal pressure, aligning with R986111054’s nominal rating; ensure your system’s requirements also account for R986111054’s 4600 PSI peak pressure capability.
Speed
R986111054, R986110938, R986110971, and R986110608 list 2600 max speed, while R986111159 lists 2300—verify max speed compatibility if your application runs near the upper RPM range.
Quick Selection Guide
Choose: R986111054
Because: When you need a 74cc unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2600 max speed to match the current specification.
Choose: Higher displacement model
Because: Choose R986111159 (100cc) when your flow requirement is higher than a 74cc unit can provide at the same operating speed, and your setup can accommodate a 2300 max speed rating.
Choose: Lower pressure model
Because: None of the listed similar products have a lower nominal pressure than 3600 PSI, so a lower-pressure alternative is not identified within this comparison set.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re evaluating other Rexroth replacements for different OEM cross-references, you may also consider R986111250 where the machine specification calls for a different configuration.
