Bosch Rexroth R986110067 (Series 52/53) is a reliable OEM replacement for CAT 178-5195, built to match fit and hydraulic performance for consistent operation.
Technical Specifications
Flow Performance
With a 74 cc displacement, the R986110067 delivers predictable flow output per revolution to support stable actuator response and repeatable machine cycles. Its performance is designed to remain consistent across operating demands, helping reduce flow variability that can affect control. The 52/53 series configuration supports dependable hydraulic delivery for OEM-equivalent operation.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit maintains hydraulic performance under sustained load and transient pressure events. It supports speeds up to 2600 RPM, enabling reliable operation across typical duty cycles without sacrificing consistency. These ratings help preserve output stability and component life in demanding hydraulic systems.
Installation
Engineered as a direct replacement for CAT 178-5195, the R986110067 is intended to install with OEM-equivalent fit and interface alignment. It is designed to replace the original unit without requiring modifications.
Features and Benefits
- 74 cc displacement: Provides consistent flow per revolution to support repeatable machine response and predictable hydraulic control.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Handles continuous working pressure with headroom for peak events to reduce pressure-related interruptions.
- 2600 RPM maximum speed: Supports reliable operation at higher rotational speeds to maintain performance across varying duty cycles.
Operational Information
Designed to operate reliably up to 3600 PSI nominal pressure (4600 PSI peak) and speeds to 2600 RPM, maintaining stable output under typical hydraulic system conditions. Use within the machine’s established operating environment and fluid management practices to support consistent long-term reliability.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
Within the 52/53 series options listed, selection is primarily driven by matching displacement (flow per revolution) while confirming the same 3600 PSI nominal pressure class and any max speed differences. If you’re comparing other hydraulic pumps, confirm the circuit type, control style, and installation details before ordering.
?? 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 |
|---|---|---|---|---|
| R986110067 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110940 | 63cc | 3600 PSI | 2600 | 53 |
| R986111411 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111616 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111395 | 60cc | 3600 PSI | 2600 | 52 |
Key Differences
Displacement
R986110067 is 74cc; the alternatives range from 45cc (R986111411) to 100cc (R986111616), with 60cc (R986111395) and 63cc (R986110940) in between—choose higher displacement for more flow per revolution and lower displacement when less flow is needed. For broader comparisons across axial piston pumps, also consider control type and efficiency at your operating speed/pressure.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986110067 additionally specifies a 4600 PSI peak rating, so confirm your system’s pressure requirements and any peak events against the part’s ratings.
Speed
R986110067 and the 45cc/60cc/63cc options list 2600 max speed, while the 100cc option (R986111616) lists 2300—ensure the selected unit meets your operating speed range.
Quick Selection Guide
Choose: R986110067
Because: When you need 74cc displacement with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2600 max speed.
Choose: Higher displacement model
Because: When your required flow per revolution is higher than 74cc (e.g., 100cc R986111616), and your operating speed is compatible with the listed max speed.
Choose: Lower displacement model
Because: When your required flow per revolution is lower than 74cc (e.g., 63cc R986110940, 60cc R986111395, or 45cc R986111411) while staying within the same 3600 PSI nominal pressure class.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re unsure, provide the pump nameplate data and the OEM part number so we can help cross-check against options like R986111250 when displacement or controls differ.
