Compatibility & Applications
Direct Replacement Information
This Rexroth R986111102 replaces CAT 242-6085 in closed-loop and open-circuit hydrostatic system applications.
- Hydraulic systems requiring 74cc displacement variable-flow control, including many piston pumps used in mobile equipment
- Circuits operating at 3600 PSI nominal pressure with variable displacement demand
- Axial piston variable pump applications for hydrostatic drive, implement, and auxiliary hydraulic circuits up to 2600 max speed
Common Applications
This Bosch Rexroth R986111102 is commonly used in:
- construction and earthmoving equipment hydraulic systems
- mobile equipment hydrostatic drive and implement functions
- industrial power units and machinery requiring variable-flow hydraulic pumps supply
Important: Verify mounting pattern, shaft interface, rotation, control type, and port configurations match the existing CAT 242-6085 installation before ordering.
Product Selection Guide
Within the 52/53 series options shown, the primary selection driver is displacement (flow capability), while nominal pressure is consistent at 3600 PSI and speed is generally 2600 with one lower-speed higher-displacement option.
?? 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 |
|---|---|---|---|---|
| R986111102 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111282 | 60cc | 3600 PSI | 2600 | 52 |
| R986111374 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111220 | 60cc | 3600 PSI | 2600 | 52 |
| R986111115 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986111102 is 74cc, positioned between the 45cc (R986111374) and 60cc (R986111282/R986111220) options for lower flow needs, and the 100cc (R986111115) option for higher flow requirements.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986111102 additionally specifies 4600 PSI peak pressure, so confirm your system’s peak/transient requirements when matching replacements.
Speed
Most options list 2600 max speed (including R986111102), while the 100cc option (R986111115) lists 2300, which may influence selection if your operating speed approaches maximum limits.
Quick Selection Guide
Choose: R986111102
Because: When you need a 74cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak capability, and up to 2600 max speed in a 52/53 series replacement.
Choose: Higher displacement model
Because: Choose R986111115 (100cc) when you need higher displacement than 74cc for greater flow, and your application can accommodate its 2300 max speed.
Choose: Lower displacement model
Because: Choose R986111282 or R986111220 (60cc) or R986111374 (45cc) when your required flow is lower than 74cc, while maintaining 3600 PSI nominal pressure and up to 2600 max speed.
Compatibility: Verify mounting pattern, shaft configuration, port sizes, and the required speed/pressure limits match your existing installation before selecting a replacement. If you’re comparing similar Rexroth options for other OEM cross-references, you may also consider R986111250 for related applications.
