Bosch Rexroth R986110676 (Series 52/53) is a performance-focused OEM replacement for CAT 476-6616, built to deliver compatible fit and consistent hydraulic output under demanding pressure and speed conditions.
Technical Specifications
Flow Performance
With a 100 cc displacement, the R986110676 provides predictable volumetric output per revolution for stable system response. Its flow delivery is designed to remain consistent across operating speeds up to 2300 RPM, supporting repeatable actuator and circuit performance.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and up to 4600 PSI peak pressure, this unit is built to maintain performance under high-load transients. The Series 52/53 design supports sustained operation at up to 2300 RPM while preserving reliable output characteristics in demanding duty cycles.
Installation
Engineered as a direct OEM replacement for CAT 476-6616, the R986110676 is intended to match the original interface for straightforward installation. It is designed for OEM-fit replacement without modifications.
Features and Benefits
- 100 cc displacement: Delivers consistent output per revolution for predictable system response and controllable flow behavior.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high-load operation and short-duration pressure spikes without requiring de-rating for typical transient events.
- 2300 RPM maximum speed (Series 52/53): Maintains usable hydraulic output at higher operating speeds to support fast cycle times and responsive machine operation.
Operational Information
Operate within the specified limits of 3600 PSI nominal (4600 PSI peak) and up to 2300 RPM to maintain stable performance. The 75 lb assembly is intended for reliable service in continuous-duty hydraulic environments when run 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 3600 PSI nominal pressure class, so selection primarily comes down to matching displacement (flow needs) and allowable speed for your duty cycle. If you’re comparing options across our broader hydraulic pumps lineup, confirm the circuit type and control style are equivalent.
?? 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 |
|---|---|---|---|---|
| R986110676 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110061 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110593 | 200cc | 3600 PSI | 2300 | 52/53 |
| R986111064 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110062 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110676 is 100cc, while the comparison options include smaller 71cc/74cc units (R986110062, R986110061, R986111064) for lower flow demand and a larger 200cc unit (R986110593) for higher flow demand.
Pressure Rating
All listed comparison parts show 3600 PSI, matching R986110676’s nominal pressure; however, R986110676 also lists a 4600 PSI peak pressure, so confirm your system’s transient/peak requirements when selecting a replacement.
Speed
R986110676 and the 200cc option (R986110593) are listed at 2300 max speed, while the 71cc/74cc options list 2600, which may be preferable if your operating speed is higher.
Quick Selection Guide
Choose: R986110676
Because: When you need a Series 52/53 replacement with 100cc displacement, 3600 PSI nominal pressure, 4600 PSI peak capability, and a 2300 max speed limit.
Choose: Higher displacement model
Because: Choose R986110593 (200cc) when your required flow/displacement is higher than 100cc while staying in the same 3600 PSI nominal pressure class.
Choose: Lower displacement model
Because: Choose R986110062 (71cc) or R986110061/R986111064 (74cc) when your flow/displacement requirement is lower than 100cc and you may benefit from the higher listed max speed (2600).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm nominal/peak pressure and max speed requirements align with your system. This is especially important when swapping between similar piston pumps where control options and interfaces can vary.
