Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this component is designed to sustain hydraulic loading while maintaining repeatable output characteristics. Operation up to 2600 RPM supports high-cycle use while preserving performance stability within the specified pressure envelope.
Installation
Designed as a direct OEM replacement for CAT 186-3732, the R986110068 installs with OEM-fit compatibility and requires no modifications. Series 52/53 configuration supports straightforward integration into the existing mounting and hydraulic interface.
Features and Benefits
- 45 cc displacement: Provides a fixed, repeatable displacement per revolution for consistent flow output and predictable actuator response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports continuous operation at 3600 PSI with headroom to 4600 PSI peak for transient load events.
- 2600 RPM maximum speed: Enables stable operation at rotational speeds up to 2600 RPM for responsive hydraulic performance in high-cycle operation.
Operational Information
Operate within the specified 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2600 RPM maximum speed to maintain consistent performance. The 40 lb assembly is suited for applications requiring stable hydraulic output and repeatable operation under sustained load.

Compatibility & Applications
Direct Replacement Information
This Rexroth R986110068 replaces CAT 186-3732 in closed-loop or open-circuit hydraulic drive and implement system applications.
- Hydraulic systems requiring 45cc displacement variable output (see related piston pumps for similar configurations)
- Circuits operating at 3600 PSI nominal pressure
- Axial piston variable pump applications up to 2600 max speed, including hydrostatic drive loops and load-sensing/pressure-compensated implement circuits
Common Applications
This Bosch Rexroth R986110068 is commonly used in:
- construction and earthmoving equipment
- material handling equipment
- industrial hydraulic power units and production machinery (browse our full range of hydraulic pumps for system builds and replacements)
Important: Verify mounting interface, shaft configuration, rotation, and port locations match the existing CAT 186-3732 installation and system circuit type before installation.
Product Selection Guide
These Series 52/53 components share a 3600 PSI nominal pressure rating, so selection primarily comes down to matching displacement (flow) and any available speed limits to your existing 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 |
|---|---|---|---|---|
| R986110068 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111618 | 85cc | 3600 PSI | 2500 | 52/53 |
| R986111457 | 128cc | 3600 PSI | N/A | 52/53 |
| R986110934 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110678 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110068 and R986110678 are 45cc options for matching existing 45cc flow requirements, while R986110934 (74cc), R986111618 (85cc), and R986111457 (128cc) increase displacement for higher flow needs at the same nominal pressure rating.
Pressure Rating
All listed comparison products are rated at 3600 PSI nominal pressure; the current product (R986110068) also specifies a 4600 PSI peak pressure, so confirm peak-pressure requirements when substituting across part numbers.
Speed
R986110068, R986110934, and R986110678 list 2600 max speed, while R986111618 lists 2500 and R986111457 is not specified (N/A), so verify allowable speed when selecting higher-displacement or unspecified-speed alternatives.
Quick Selection Guide
Choose: R986110068
Because: When you need a 45cc displacement with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and 2600 max speed to match the current specification set.
Choose: Higher displacement model
Because: When flow requirements exceed 45cc, consider R986110934 (74cc), R986111618 (85cc), or R986111457 (128cc), and confirm speed limits (2600, 2500, or N/A respectively) align with your operating speed. If you need additional Series 52/53 options, compare against R986111250 as well.
Choose: Lower pressure model
Because: Not applicable with the provided comparison set, as all listed alternatives are 3600 PSI nominal; if your system operates at lower pressures, select a part explicitly rated for that duty after confirming all required specifications.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, nominal/peak pressure requirements, and allowable speed before substituting.
