Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, this unit is designed to sustain performance under high-load hydraulic conditions. Operation up to 2300 RPM supports high duty-cycle use while maintaining controlled performance within the specified pressure envelope.
Installation
Engineered as an OEM replacement for CAT 355-2395, the R986110786 is intended to match OEM fit and interface requirements for straightforward installation. It is a direct replacement designed to install without modifications when replacing the specified CAT component.
Features and Benefits
- 100 cc displacement: Provides predictable volume output per revolution to support consistent machine response and repeatable hydraulic control.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Handles high working pressures with defined peak capacity to support transient load events without exceeding specified limits.
- 2300 RPM maximum speed capability: Supports higher operating speeds for responsive performance while staying within the specified speed range.
Operational Information
Designed for hydraulic operation up to 3600 PSI nominal and 4600 PSI peak, with rotational speeds up to 2300 RPM. Maintain operation within the specified pressure and speed limits to support consistent performance and reliability.
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 rating, so selection is primarily driven by required displacement (flow per revolution) and allowable operating speed. If you are comparing other piston pumps, confirm the control type and porting match your circuit needs.
?? 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 |
|---|---|---|---|---|
| R986110786 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110939 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111503 | 85cc | 3600 PSI | 2500 | 52/53 |
| R986110669 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110771 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110786 is 100cc for higher flow per revolution; the comparison parts step down to 85cc, 71cc, and 45cc options, which better fit lower-flow requirements and can help avoid oversizing.
Pressure Rating
All listed comparison parts show 3600 PSI pressure rating, matching the current product’s nominal pressure; note that only R986110786 includes a stated peak pressure of 4600 PSI in the provided specs.
Speed
R986110786 is rated to 2300 max speed, while the comparison parts list higher max speeds (2500–2600), which may be advantageous if your operating speed is above 2300.
Quick Selection Guide
Choose: R986110786
Because: When you need 100cc displacement with 3600 PSI nominal pressure and operation up to 2300 max speed (and your duty cycle requires the stated 4600 PSI peak capability).
Choose: Lower displacement model (R986111503 85cc, R986110939 71cc, R986110669/R986110771 45cc)
Because: When your system flow requirement is lower than a 100cc unit, or when you want to better match displacement to the circuit while maintaining the same 3600 PSI nominal pressure rating.
Choose: Higher speed-listed alternatives (R986110939, R986110669, R986110771 at 2600; R986111503 at 2500)
Because: When your application requires operation above 2300 speed and a listed max speed of 2500–2600 is needed, while keeping the same 3600 PSI nominal pressure rating.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, pressure, and speed ratings align with your system requirements. If you need an alternate cross-reference for specific equipment families, related options may include R986111250.
