Bosch Rexroth R986110978 (Series 52) is a direct OEM replacement for CAT 443-8469, delivering reliable 60 cc displacement performance with OEM-fit compatibility for cost-effective maintenance.
Technical Specifications
Flow Performance
With a 60 cc displacement, R986110978 provides consistent, predictable hydraulic output across operating speeds up to 2600 RPM. The fixed displacement supports straightforward system tuning and stable response, helping maintain required performance without added system complexity. This balance of output and simplicity supports a cost-effective replacement strategy.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, the Series 52 design maintains performance under demanding load conditions. Operation up to 2600 RPM supports high-duty cycles while staying within defined limits. The 48.5 lb unit mass reflects a robust build intended to sustain pressure and speed capability over time.
Installation
Designed as an OEM replacement for CAT 443-8469, this unit is intended for direct fit installation with no modifications required. Maintain standard mounting alignment and hydraulic connections consistent with the existing OEM configuration.
Features and Benefits
- 60 cc displacement: Delivers consistent per-revolution output for stable system behavior and predictable actuator response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports continuous operation at 3600 PSI with headroom to 4600 PSI peak to manage transient load spikes.
- 2600 RPM maximum speed (Series 52): Enables required flow potential at higher operating speeds while keeping operation within specified limits for dependable performance.
Operational Information
Operate within the stated limits of 3600 PSI nominal, 4600 PSI peak, and up to 2600 RPM maximum speed to maintain reliable performance. Suitable for hydraulic circuits that require consistent displacement output and stable operation under varying loads.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Compatibility & Applications
Direct Replacement Information
This Bosch Rexroth R986110978 replaces CAT 443-8469 in high-pressure mobile and industrial hydraulic pump applications.
- Closed-loop or open-loop hydrostatic circuits requiring 60cc variable displacement
- Hydraulic systems operating at 3600 PSI nominal pressure with up to 2600 RPM input speed
- Pump supply for proportional/servo-controlled functions, pressure-compensated circuits, and load-sensing style control architectures (where applicable)
Common Applications
This Bosch Rexroth R986110978 is commonly used in:
- construction and earthmoving equipment hydraulics
- material handling machines and lift systems
- industrial power units and production machinery hydraulics
Important: Confirm mounting interface, shaft configuration, porting, control type, and case drain requirements match the existing CAT 443-8469 installation before replacement.
Product Selection Guide
These Series 52 components share the same nominal pressure class and similar maximum speeds, with selection primarily driven by displacement (flow per revolution) needs. If you’re comparing across hydraulic pumps, confirm the control type and mounting interface match your system architecture.
?? 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 |
|---|---|---|---|---|
| R986110978 | 60cc | 3600 PSI | 2600 | 52 |
| R986111126 | 74cc | 3600 PSI | 2600 | 52/53 |

Key Differences
Displacement
R986110978 is 60cc, while alternatives range from 63cc (R986110940) up to 85cc (R986111503); higher displacement increases potential flow for a given speed, while lower displacement can better match lower flow demand.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986110978 additionally specifies 4600 PSI peak, so confirm peak-pressure requirements when cross-referencing replacements.
Speed
Most options list 2600 max speed (including R986110978), while R986111503 lists 2500; verify your required operating speed stays within the selected model’s limit.
Quick Selection Guide
Choose: R986110978
Because: When you need a 60cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2600 max speed in a Series 52 replacement.
Choose: Higher displacement model
Because: When flow requirements exceed a 60cc displacement at your available speed—consider 63cc (R986110940), 72cc (R986110675), 74cc (R986111126), or 85cc (R986111503) depending on the needed increase. For broader options in this family, browse our piston pumps selection.
Choose: Lower pressure model
Because: Not applicable within this comparison set, as all listed alternatives are rated 3600 PSI nominal; if your system operates at lower pressures, verify an appropriate lower-rated option outside this list.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, nominal/peak pressure requirements, and maximum speed align with your system.
