Bosch Rexroth R986110944 (Series 52/53) is a direct OEM replacement for BOBCAT 6689769, engineered to restore specified hydraulic performance with reliable fit and compatibility.
Technical Specifications
Flow Performance
With a 45 cc displacement, R986110944 delivers consistent volumetric output per revolution for predictable actuator response and control. The displacement supports stable flow characteristics across the operating range up to 2600 max speed, maintaining repeatable machine function under varying load demands.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, the unit is designed to sustain performance under high-load duty cycles without exceeding specified limits. Operation up to 2600 max speed supports required cycle times while maintaining controlled hydraulic behavior within the component’s pressure envelope.
Installation
Designed as a direct replacement for BOBCAT 6689769, R986110944 matches OEM form/fit expectations for straightforward installation. Intended to install without modifications when replacing the original component.
Features and Benefits
- 45 cc displacement: Provides predictable flow per revolution for consistent motion and repeatable cycle performance.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high working loads with defined pressure headroom for transient spikes within the specified peak rating.
- 2600 max speed capability: Enables required operating speed range to maintain hydraulic response and cycle timing within specification.
Operational Information
Operate within the specified limits of 3600 PSI nominal, 4600 PSI peak, and up to 2600 max speed to maintain stable performance. As a 40 lb Series 52/53 component, it is intended for continuous hydraulic service where consistent output and reliability are required.

Product Selection Guide
These Series 52/53 components share a 3600 PSI nominal pressure class, so selection is primarily driven by displacement (flow) and allowable speed differences relative to your 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 |
|---|---|---|---|---|
| R986110944 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110073 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110045 | 28cc | 3600 PSI | 3000 | 52/53 |
| R986110050 | 28cc | 3600 PSI | 3000 | 52/53 |
| R986110060 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986110944 is 45cc, positioned between lower-displacement 28cc options (R986110045/R986110050) and higher-displacement 71cc (R986110073) and 100cc (R986110060) models; choose higher displacement when you need more flow at a given speed, or lower displacement when you want reduced flow.
Pressure Rating
All listed comparison models show 3600 PSI pressure, while R986110944 is specified at 3600 PSI nominal with a 4600 PSI peak; confirm your system’s operating and transient pressure needs align with the component ratings.
Speed
R986110944 and R986110073 are listed at 2600 max speed, the 28cc models are higher at 3000, and the 100cc model is lower at 2300; match max speed to your prime mover and duty cycle to avoid overspeed.
Quick Selection Guide
Choose: R986110944
Because: When you need a 45cc displacement with 3600 PSI nominal pressure capability, 4600 PSI peak rating, and up to 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: Choose R986110073 (71cc) or R986110060 (100cc) when your required flow exceeds what a 45cc unit can provide at your available operating speed.
Choose: Lower displacement model
Because: Choose R986110045 or R986110050 (28cc) when you need lower flow and can benefit from the higher listed max speed (3000) compared with 2600.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, pressure (nominal/peak), and max speed align with your system requirements.
