The Bomag 05813121 Steering Pump is a genuine OEM component designed for Bomag BW 177, BW 178, BW 212, BW 213, and BW 214 series single drum rollers, as well as the C 850 C single drum roller. As a direct OEM replacement, this steering pump matches the original unit's specifications, ensuring a clean installation with no adaptation. Sourced directly from Bomag, part number 05813121 is the correct factory-specified pump for these machines, giving you confidence in fitment before the part ever arrives on site.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact hydraulic output and pressure specifications, ensuring the steering system performs exactly as designed for heavy single drum roller applications.
- Direct-Fit Replacement — engineered to match the original mounting configuration and port layout, allowing straightforward installation on compatible Bomag single drum rollers.
- Broad Single Drum Roller Coverage — fits BW 177, BW 178, BW 212, BW 213, and BW 214 series single drum rollers across multiple variants, including DH-3, PDH-3, and USA-spec models, as well as the C 850 C single drum roller.
- Restores Full Steering Response — a worn or failing steering pump causes sluggish, inconsistent, or unresponsive steering, reducing operator control and machine safety on the job. Replacing it with this pump restores full hydraulic assist.
- Operator Safety — on large ride-on single drum rollers, responsive hydraulic steering is a critical safety function. Using the correct OEM-specified pump ensures the steering circuit operates within its designed pressure range at all times.
The steering pump is the hydraulic heart of the roller's steering system, generating the pressurized fluid flow that allows the operator to articulate the machine with controlled, consistent effort. Without adequate pump output, steering becomes heavy, unpredictable, or completely unresponsive — a serious hazard when maneuvering a large single drum roller on a compaction site. A failed or degraded pump can also cause excessive heat buildup in the hydraulic circuit, accelerating wear on other steering components. Replacing a worn unit promptly with a properly specified pump keeps the steering system operating safely within its designed parameters.
