Bosch Rexroth R986111247 (Series 31*) is a reliable OEM replacement for CAT 358-4992, built to match the required 110 cc displacement performance and maintain dependable hydraulic operation.
Technical Specifications
Flow Performance
With a 110 cc displacement, the R986111247 delivers consistent output per revolution for predictable system response. Stable performance is maintained up to a maximum speed of 2200, supporting steady flow characteristics across operating conditions. The Series 31* design is intended for repeatable operation where reliability is critical.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, this unit is designed to sustain performance under demanding pressure loads. Operation up to 2200 max speed supports reliable duty cycles without compromising pressure capability. The 88 lb build reflects a robust configuration intended to maintain hydraulic performance over time.
Installation
Designed as a direct OEM replacement for CAT 358-4992, the R986111247 fits the intended mounting and interface without modifications. Installation is straightforward when replacing like-for-like in the same Series 31* configuration.
Features and Benefits
- 110 cc displacement: Provides 110 cc per revolution output for predictable actuation and consistent system response.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports continuous operation at 3600 PSI with headroom up to 4600 PSI peak to handle transient load spikes.
- 2200 maximum speed capability: Maintains reliable performance up to 2200 max speed for stable hydraulic output in demanding operating cycles.
Operational Information
Operate within the specified 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2200 max speed to support reliable performance. Consistent operation is expected when the unit is used within these ratings in a properly maintained hydraulic system.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
Within the 31* series, these parts are primarily differentiated by displacement (flow capacity) and allowable speed, while nominal pressure rating is consistent across the listed 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.
| Part Number | Displacement | Pressure | Max Speed | Series |
|---|---|---|---|---|
| R986111247 | 110cc | 3600 PSI | 2200 | 31* |
| R986110934 | 74cc | 3600 PSI | 2600 | 52/53 |

| R986110968 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986111247 is 110cc (highest listed), compared with 100cc (R986110968), 74cc (R986110934/R986110713), and 45cc (R986110669); higher displacement is typically chosen when you need more flow per revolution, while lower displacement can better suit lower flow requirements.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986111247 additionally specifies 4600 PSI peak pressure, so ensure your system’s peak events align with the part’s stated peak capability.
Speed
Maximum speed varies: R986111247 is 2200, R986110968 is 2300, and the 74cc/45cc options list 2600; if your duty cycle requires higher operating speed, select a model with a max speed that meets or exceeds your requirement.
Quick Selection Guide
Choose: R986111247
Because: When you need 110cc displacement with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and a max speed of 2200.
Choose: Higher displacement model
Because: When flow requirements exceed the 110cc displacement of R986111247 (select a model with a higher displacement than 110cc if available within your approved configuration).
Choose: Lower pressure model
Because: When system operates at lower pressures for cost savings (only if an alternative with a lower pressure rating is approved for your system; the listed comparison parts are all 3600 PSI nominal).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re comparing options across our broader hydraulic pumps lineup, use these interface details to narrow down equivalent replacements.
