Bosch Rexroth R986111123 Axial Piston Variable Pump | Replaces CAT 341-7664 | 110cc | 3600 PSI

Product Selection Guide

These 31* components are best compared by matching displacement (flow per revolution) first, then confirming the same pressure rating and allowable speed for your duty cycle. If you’re comparing other piston pumps, start with the same approach to avoid mismatched flow and performance.

?? 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.

Key Differences

Displacement

R986111123 and R986110083 are 110cc options for higher flow per revolution, while R986110970 (45cc) and the 71cc/74cc models (R986110090/R986110581) suit lower flow needs or finer control; choose displacement based on required flow at your available operating speed. If you’re evaluating other hydraulic pumps for the same machine, keep the same displacement-first comparison to maintain predictable system response.

Pressure Rating

All compared models list 3600 PSI nominal pressure, so selection is primarily driven by displacement and speed; for R986111123 specifically, also confirm your system stays within its 4600 PSI peak limit.

Speed

R986111123 (and R986110083) are rated to 2200 max speed, while the smaller-displacement alternatives listed are rated to 2600; if your prime mover speed is higher, a 2600-rated option may be a better match provided displacement meets flow needs.

Quick Selection Guide

Choose: R986111123

Because: When you need a 31* unit with 110cc displacement, 3600 PSI nominal pressure, 4600 PSI peak capability, and a 2200 max speed rating to match the existing installation requirements.

Choose: R986110083

Because: When you need the same 110cc displacement, 3600 PSI nominal pressure, and 2200 max speed as R986111123 for a close performance match within the 31* series.

Choose: R986110970 / R986110090 / R986110581

Because: When you need lower displacement (45cc, 71cc, or 74cc) and/or a higher 2600 max speed rating, and your required flow can be met with the smaller displacement at your operating speed.

Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, nominal pressure, peak pressure, and max speed align with your system requirements. If you’re cross-referencing adjacent options in this family, you may also want to review R986110076 for fit and performance comparison.
