Compatibility & Applications
Direct Replacement Information
This Rexroth R986111323 replaces CAT 423-0089 in closed-loop and open-circuit hydraulic pumps system applications.
- Hydraulic systems requiring 63cc displacement variable flow control
- Circuits operating at 3600 PSI nominal pressure
- Mobile and industrial hydrostatic drive circuits and implement hydraulics using an axial piston variable pump
- Systems with pump speeds up to 2600 RPM max
Common Applications
This Bosch Rexroth R986111323 is commonly used in:
- construction and earthmoving equipment
- agricultural machinery
- material handling equipment
- industrial power units and production machinery
Important: Confirm mounting interface, shaft type, rotation, control configuration, and port locations match the existing CAT 423-0089 installation before replacement.
Product Selection Guide
These Series 53 components are best compared by displacement (flow per revolution) and maximum speed, since nominal pressure is consistent across the listed options. If you’re comparing similar piston pumps, displacement and speed are typically the fastest way to narrow down the correct frame size and duty cycle fit.
?? 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 |
|---|---|---|---|---|
| R986111323 | 63cc | 3600 PSI | 2600 | 53 |
| R986110606 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110955 | 60cc | 3600 PSI | 2600 | 52 |
| R986111092 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111098 | 71cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111323 is 63cc, close to the 60cc option (R986110955) and below the 71cc option (R986111098); the 100cc options (R986110606, R986111092) provide higher displacement for higher flow needs at the same speed range shown.
Pressure Rating
All listed comparison products show 3600 PSI nominal pressure, matching R986111323; for R986111323, also confirm your system stays within its 4600 PSI peak pressure limit.
Speed
R986111323 is rated to 2600 max speed, aligning with the 60cc and 71cc options (2600) and exceeding the 100cc options listed (2300), which may matter in higher-RPM duty cycles.
Quick Selection Guide
Choose: R986111323
Because: When you need a 63cc unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2600 max speed.
Choose: Higher displacement model
Because: When your required displacement is higher than 63cc (e.g., 71cc or 100cc) to achieve more flow per revolution, and your operating speed aligns with the model’s max speed rating.
Choose: Lower pressure model
Because: When your system operates at lower pressures and a lower pressure-rated component is acceptable; confirm the replacement’s nominal and peak pressure ratings meet your system requirements.
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 limits. If you’re also evaluating other Rexroth replacements used in similar mobile equipment platforms, you may want to compare against R986110940 where applicable.
