Product Selection Guide

These Series 52/53 components share a 3600 PSI nominal pressure rating, with primary selection differences driven by displacement (flow capacity) and maximum speed limits across models.

?? 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

R986110970 is 45cc for lower flow needs, while the comparison options increase displacement to 63cc (R986110674), 71cc (R986111098), or 100cc (R986110679/R986110680) when higher flow is required at similar nominal pressure.

Pressure Rating

All listed comparison products are rated at 3600 PSI nominal; R986110970 additionally lists a 4600 PSI peak pressure, so confirm your system’s peak/relief settings align with the part you select.

Speed

Maximum speed is 2600 for R986110970 and for the 63cc/71cc options, while the 100cc options list 2300, which can matter if your drive speed is near the upper limit.

Quick Selection Guide

Choose: R986110970

Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure, and up to 2600 max speed in a Series 52/53 replacement.

Choose: Higher displacement model

Because: When your required flow exceeds what a 45cc unit can provide—consider 63cc (R986110674), 71cc (R986111098), or 100cc (R986110679/R986110680) while maintaining a 3600 PSI nominal rating.

Choose: Lower pressure model

Because: When the system operates at lower pressures than 3600 PSI nominal and a lower-rated option is acceptable; select only after confirming your required nominal and peak pressure limits.

Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation.

Compatibility & Applications

Direct Replacement Information

This Rexroth R986110970 replaces CAT 418-2203 in mobile hydraulic closed-loop and open-circuit pump drive applications.

• Mobile hydraulic systems requiring 45cc displacement variable flow control
• Circuits operating at 3600 PSI nominal pressure with load-sensing or pressure-compensated control
• Hydraulic pump drive applications up to 2600 max speed supporting implement, steering, and auxiliary functions

Common Applications

This Bosch Rexroth R986110970 is commonly used in:

• mobile hydraulics
• construction equipment (backhoe loaders, compact loaders)
• agricultural machinery
• material handling equipment

Important: Verify mounting interface, shaft configuration, rotation, and porting match the existing CAT 418-2203 installation before replacement. If you’re comparing options across our hydraulic pumps lineup, confirm the control type and case drain requirements for your circuit.
