Bosch Rexroth R986110610 (Series 52) is a direct OEM replacement for CAT 318-8481, delivering reliable 60 cc displacement performance with OEM-fit compatibility for predictable hydraulic operation.
Technical Specifications
Flow Performance
With a 60 cc displacement, the R986110610 provides consistent volumetric output per revolution to support stable actuator and drive response. Its performance profile is optimized to deliver the required flow capability without over-specifying the unit, supporting cost-effective system operation. Designed for standard hydraulic duty, it maintains predictable flow behavior across its rated operating range.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit supports high-load cycles while maintaining controlled hydraulic performance. A maximum speed of 2600 RPM enables responsive operation across typical machine duty conditions. These ratings help sustain performance under pressure and speed demands without requiring oversizing.
Installation
Engineered as an OEM replacement for CAT 318-8481, the R986110610 is intended to install as a direct fit with standard mounting and interface compatibility. It is designed to replace the original unit without modifications to the hydraulic system layout.
Features and Benefits
- 60 cc displacement: Delivers a consistent 60 cc per revolution output for predictable flow and controllable machine response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports continuous operation at 3600 PSI with 4600 PSI peak handling for load spikes and transient events.
- 2600 RPM maximum speed (Series 52 design): Enables operation up to 2600 RPM to maintain required hydraulic output across variable operating speeds while keeping system sizing cost-effective.
Operational Information
Operate within the rated 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2600 RPM maximum speed for stable, repeatable performance. Built for standard hydraulic operating conditions where consistent output and reliable duty-cycle behavior 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 Rexroth R986110610 replaces CAT 318-8481 in closed-loop and open-loop hydrostatic hydraulic system applications.
- Hydraulic systems requiring 60cc/rev variable displacement flow control
- Circuits operating at 3600 PSI nominal pressure with load-sensing or pressure-compensated control schemes
- Axial piston variable pump duties up to 2600 RPM for hydrostatic drive, implement, and auxiliary hydraulic pumps circuits
Common Applications
This Bosch Rexroth R986110610 is commonly used in:
- construction and earthmoving equipment hydraulic systems
- mobile machinery hydrostatic drive systems
- industrial power units and process hydraulics
Important: Confirm mounting interface, shaft configuration, porting, control type, and rotation match the existing CAT 318-8481 installation before replacement.
Product Selection Guide
Within Series 52, R986110610 (60cc) sits between the higher-displacement 71–74cc options and the lower-displacement 45cc option, while all listed models share the same nominal pressure and max speed ratings provided. For more options in this pump type, browse our piston pumps selection.
?? 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 |
|---|---|---|---|---|
| R986110610 | 60cc | 3600 PSI | 2600 | 52 |
| R986110067 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110100 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110046 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110112 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110610 is 60cc versus 71cc (R986110100/R986110046), 74cc (R986110067), and 45cc (R986110112); choose higher displacement when you need more flow per revolution, or lower displacement when you want reduced flow per revolution.
Pressure Rating
All comparison models are listed at 3600 PSI nominal pressure; R986110610 additionally specifies 4600 PSI peak pressure, so confirm peak-pressure requirements when replacing.
Speed
All comparison models list a max speed of 2600, so speed is not a differentiator among these options based on the provided data.
Quick Selection Guide
Choose: R986110610
Because: When you need a Series 52 unit with 60cc displacement, 3600 PSI nominal pressure, 4600 PSI peak pressure, and 2600 max speed to match the existing specification.
Choose: Higher displacement model
Because: When your required displacement is higher than 60cc (e.g., 71cc or 74cc options) to increase flow per revolution while keeping the same listed 3600 PSI nominal pressure and 2600 max speed.
Choose: Lower pressure model
Because: None of the listed alternatives are specified at a lower nominal pressure than 3600 PSI, so a lower-pressure option is not identified from the provided comparison set.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, nominal/peak pressure requirements, and max speed align with your system.
