Bosch Rexroth R986111358 (Series 52/53) is an OEM replacement for CAT 583-4756, built to restore original hydraulic performance with reliable, direct-fit compatibility.
Technical Specifications
Flow Performance
With a 100 cc displacement, the R986111358 delivers consistent volumetric output per revolution for predictable actuator and motor response. Performance is maintained across a wide operating range up to 2300 max speed, supporting stable flow delivery under varying load conditions.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is designed to sustain high-load hydraulic operation without sacrificing performance consistency. The Series 52/53 design supports reliable operation up to 2300 max speed, helping maintain output stability in demanding duty cycles.
Installation
Engineered as a direct OEM replacement for CAT 583-4756, the R986111358 is intended to match the original mounting and interface requirements. It installs as a drop-in replacement with no modifications required.
Features and Benefits
- 100 cc displacement: Provides predictable volume per revolution for consistent system response and repeatable machine control.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high-load operation with defined pressure headroom for transient spikes up to 4600 PSI.
- 2300 max speed rating: Maintains stable hydraulic output at operating speeds up to 2300 for responsive performance across the machine’s working range.
Operational Information
Optimized for high-pressure hydraulic systems operating up to 3600 PSI nominal with intermittent peaks to 4600 PSI, and speeds up to 2300. The 75 lb assembly is suited for sustained duty where consistent output and repeatable performance are required.
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 mainly comes down to matching displacement (flow per revolution) and allowable speed to your system’s requirements. If you’re comparing similar piston pumps, confirm both continuous and peak duty conditions.
?? 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 |
|---|---|---|---|---|
| R986111358 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110806 | 110cc | 3600 PSI | 2200 | 31* |
| R986110676 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110961 | 60cc | 3600 PSI | 2600 | 52 |
| R986110630 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986111358 is 100cc; R986110676 and R986110630 also match at 100cc for like-for-like flow per revolution, while R986110806 increases to 110cc for higher flow and R986110961 drops to 60cc for lower flow needs.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986111358 additionally specifies a 4600 PSI peak pressure, so confirm peak/overload requirements when substituting.
Speed
Maximum speed varies by model (2300 for R986111358, 2200 for R986110806, 2600 for R986110961), so choose a unit that meets or exceeds your operating speed without exceeding its limit.
Quick Selection Guide
Choose: R986111358
Because: When you need a 100cc unit rated for 3600 PSI nominal pressure with 4600 PSI peak capability and up to 2300 max speed.
Choose: Higher displacement model
Because: Choose R986110806 (110cc) when you need more flow per revolution than a 100cc unit provides and your operating speed stays within its 2200 limit.
Choose: Lower pressure model
Because: None of the listed alternatives are lower than 3600 PSI nominal; select a different part only if your system’s pressure requirements and ratings are verified to match.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re evaluating other Rexroth cross references, R986111250 may be a useful comparison point for similar build and fitment checks.
