Bosch Rexroth R986110070 (Series 52/53) is a direct OEM replacement for CAT 162-0770, engineered to maintain reliable hydraulic performance and fit within the original system interface.
Technical Specifications
Flow Performance
With a 45 cc displacement, the unit delivers consistent volumetric output per revolution for predictable actuator and circuit response. Stable flow generation supports repeatable machine behavior across the operating speed range up to 2600 RPM.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, the component is designed to maintain performance under high-load hydraulic conditions. Operation up to 2600 RPM supports sustained duty without exceeding the stated speed capability.
Installation
Designed as a direct replacement for CAT 162-0770, providing OEM-fit compatibility for mounting and hydraulic integration. Installation is intended to be drop-in with no modifications required.
Features and Benefits
- 45 cc displacement: Provides a fixed, repeatable displacement per revolution to support predictable flow output and consistent machine response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high working pressures and short-duration peak loading within the stated limits to maintain circuit performance under load.
- 2600 RPM maximum speed rating: Enables operation across a broad speed range up to 2600 RPM while maintaining specified performance capability.
Operational Information
Operate within the stated limits of 3600 PSI nominal, 4600 PSI peak, and up to 2600 RPM for consistent hydraulic output. The 40 lb assembly is suited for stable installation in systems requiring a Series 52/53 replacement profile.
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 shown, the primary selection driver is displacement (flow capacity), with all listed models sharing the same 3600 PSI nominal pressure while maximum speed varies by model.
?? 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 |
|---|---|---|---|---|
| R986110070 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110083 | 110cc | 3600 PSI | 2200 | 31* |
| R986110939 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110934 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111616 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986110070 is 45cc, while the compared models are 71cc, 74cc, 100cc, and 110cc; choose higher displacement when you need more flow than a 45cc unit can provide at a given speed.
Pressure Rating
All comparison models list 3600 PSI nominal pressure; R986110070 also specifies a 4600 PSI peak pressure, so confirm your system’s peak/transient requirements against the pump’s ratings.
Speed
R986110070, R986110939, and R986110934 are rated to 2600 max speed, while R986110083 and R986111616 are lower at 2200 and 2300 respectively; select a model whose max speed meets or exceeds your drive speed.
Quick Selection Guide
Choose: R986110070
Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak capability, and up to 2600 max speed in the 52/53 series.
Choose: Higher displacement model
Because: When your required flow exceeds what a 45cc displacement can deliver—consider 71cc (R986110939), 74cc (R986110934), 100cc (R986111616), or 110cc (R986110083) depending on the flow increase needed and allowable speed.
Choose: Lower pressure model
Because: When system operates at lower pressures for cost savings.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re comparing options across our hydraulic pumps catalog, match both the mechanical interface and the control requirements.
