Bosch Rexroth R986110084 is a precision OEM replacement hydraulic component for CAT 172-5636, engineered to match fit and deliver consistent 45 cc displacement performance for reliable system operation.
Technical Specifications
Flow Performance
With a 45 cc displacement, the R986110084 delivers predictable per-revolution output to support stable actuator response and repeatable machine function. Flow scales directly with speed up to 2600 rpm, providing controlled delivery across the operating range. The Series 52/53 design is optimized for consistent hydraulic performance under load.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, the component maintains output stability during pressure transients and demanding duty cycles. Maximum speed of 2600 rpm supports high-throughput operation while preserving controlled performance. Built on the Series 52/53 platform, it is intended to sustain performance consistency within the stated pressure and speed limits.
Installation
Designed as a direct OEM replacement for CAT 172-5636, the R986110084 is intended to match the original installation interface for straightforward fitment. When installed in the correct orientation and connected to the existing hydraulic lines, no modifications are required.
Features and Benefits
- 45 cc displacement: Provides consistent per-revolution volume for repeatable motion control and predictable system response.
- 3600 PSI nominal / 4600 PSI peak pressure ratings: Supports continuous operation at 3600 PSI and tolerates short-duration peaks up to 4600 PSI to handle load spikes.
- 2600 rpm maximum speed: Enables higher operating speed capability up to 2600 rpm to maintain required output across demanding duty cycles.
Operational Information
Operate within the stated nominal and peak pressure limits and up to 2600 rpm maximum speed to maintain stable performance. The 40 lb assembly supports robust installation in hydraulic systems where consistent output and reliability 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 R986110084 replaces CAT 172-5636 in high-pressure closed-loop and open-loop hydraulic system applications.
- Hydraulic systems requiring 45cc displacement variable flow control
- Circuits operating at 3600 PSI nominal pressure (up to 2600 RPM max speed)
- Axial piston variable pump applications for hydrostatic drives, implement hydraulics, and auxiliary high-pressure circuits—commonly specified within piston pumps configurations
Common Applications
This Bosch Rexroth R986110084 is commonly used in:
- construction equipment hydraulic power units
- mining and quarry equipment hydraulics
- industrial mobile machinery (material handling and service vehicles)
Important: Verify mounting interface, shaft configuration, rotation, and porting match the existing CAT 172-5636 installation before ordering.
Product Selection Guide
These Series 52/53 components are best compared by matching displacement and speed to your existing setup, then confirming pressure ratings align with your system requirements.

?? 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 |
|---|---|---|---|---|
| R986110084 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110937 | 110cc | 3600 PSI | 2200 | 31* |
| R986110068 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110675 | 72cc | 3600 PSI | 2600 | 52/53* |
| R986111070 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110084 is 45cc, matching other 45cc options (R986110068, R986111070) for like-for-like flow; higher displacement alternatives (72cc R986110675, 110cc R986110937) are suited when you need more flow per revolution and can accommodate the change in system behavior.
Pressure Rating
All listed comparison models show 3600 PSI nominal pressure; R986110084 also specifies a 4600 PSI peak pressure, so verify your duty cycle and peak events align with the pressure ratings required for your system.
Speed
R986110084 is rated to 2600 max speed, matching the 45cc and 72cc options shown (2600); the 110cc option lists 2200, which may be a limiting factor if your machine operates at higher shaft speeds.
Quick Selection Guide
Choose: R986110084
Because: When you need a 45cc displacement with 3600 PSI nominal pressure and up to 2600 max speed, and your system may see peak pressure events up to 4600 PSI.
Choose: Higher displacement model
Because: Choose R986110675 (72cc) or R986110937 (110cc) when required flow exceeds what a 45cc unit can provide, and you can accommodate the listed speed rating differences (notably 2200 on the 110cc model).
Choose: Lower pressure model
Because: None of the listed alternatives provide a lower nominal pressure than 3600 PSI, so select based on displacement and speed while ensuring the pressure rating matches your system.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you are cross-referencing additional Rexroth replacements for other equipment, related options include R986111250.
