Bosch Rexroth R986110041 is a Series 52/53 hydraulic unit engineered as an OEM replacement for CAT 162-3140, providing reliable performance and direct compatibility in the original installation envelope.
Technical Specifications
Flow Performance
With a 45 cc displacement, R986110041 delivers consistent volumetric output per revolution to support stable hydraulic flow under load. Its displacement class supports predictable system response and repeatable actuator speed control when operated within rated limits.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, the unit is designed to maintain performance under high-pressure duty cycles. A maximum speed of 2600 rpm supports high-cycle operation while maintaining stable hydraulic output within the specified operating range.
Installation
Designed as a direct OEM replacement for CAT 162-3140 in the Bosch Rexroth Series 52/53 form factor. Installs as an OEM-fit component without requiring modifications when replacing like-for-like.
Features and Benefits
- 45 cc displacement: Provides consistent volume per revolution for predictable flow delivery and repeatable machine response.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports high-pressure operation with defined peak capacity for transient load events.
- 2600 rpm maximum speed capability: Enables operation at higher rotational speeds to meet dynamic flow demands within rated limits.
Operational Information
Operate within 3600 PSI nominal pressure, allow for intermittent peaks up to 4600 PSI, and maintain rotational speed at or below 2600 rpm for consistent output. Component mass is 40 (as specified) and should be considered for handling and mounting support during service.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
These Series 52/53 components share similar pressure and speed classes, with displacement being the primary differentiator among the listed part numbers.
?? 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 |
|---|---|---|---|---|
| R986110041 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110939 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111503 | 85cc | 3600 PSI | 2500 | 52/53 |
| R986110078 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111250 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110041 is 45cc, while R986110939 is 71cc and R986111503 is 85cc; choose higher displacement when you need more flow at a given speed, and stay with 45cc options when matching an existing 45cc setup.
Pressure Rating
All comparison models list 3600 PSI pressure, matching R986110041 nominal pressure; ensure your system requirements do not exceed the component’s rated pressure.
Speed
Most listed options are rated 2600 max speed, while R986111503 is 2500; select a model that meets or exceeds your required operating speed range.
Quick Selection Guide
Choose: R986110041
Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure and up to 2600 max speed to match your existing Series 52/53 configuration.
Choose: Higher displacement model
Because: When flow requirements exceed what a 45cc unit can provide at your available speed—consider R986110939 (71cc) or R986111503 (85cc) while confirming pressure and speed fit your system.
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 lineup, confirm the control type and porting match your circuit (open vs. closed loop).
