The Bomag 05818402 Pump Housing is a genuine OEM component designed for Bomag BW 900 AD tandem rollers and BW 900-2, BW 900-50, BW 65 D, and BW 65 walk-behind / light rollers. Sourced directly from Bomag, this pump housing delivers an exact match to the original specification, ensuring a correct, trouble-free installation. Whether you are servicing a BW 900 AD or maintaining a BW 65 series machine, part number 05818402 is the correct OEM replacement to restore your hydraulic pump assembly to full working order.
Key Features
- Genuine OEM Hydraulic Integrity — machined to the same tolerances as the original pump housing, maintaining precise internal clearances critical to consistent hydraulic pressure and flow
- Direct-Fit Replacement — matches the original mounting pattern and port dimensions, dropping into place without modification to sealing faces or fastener points
- Broad Model Coverage — fits BW 900 AD tandem rollers and BW 900-2, BW 900-50, BW 65 D, and BW 65 walk-behind / light rollers, covering a wide range of Bomag compaction equipment
- Sustained Pump Performance — a sound housing maintains the sealing environment the pump internals depend on; a cracked or worn housing causes pressure loss, erratic drive response, and accelerated wear across the entire pump assembly
- Authentic Bomag Part — supplied as genuine OEM, so fitment, material grade, and dimensional accuracy are verified against Bomag's own engineering standards
The pump housing is the structural shell of the hydraulic pump, enclosing the rotating internals and providing the precision-bored chambers that build and direct hydraulic pressure throughout the machine. It also serves as the mounting interface between the pump and the machine's drivetrain or frame. When a pump housing develops cracks, porosity, or wear at the sealing surfaces, the pump loses the ability to maintain pressure, leading to sluggish or unresponsive drum drive, reduced vibration output, and potential contamination of the hydraulic circuit. Replacing a damaged housing with a correct OEM component like the part restores the sealed, high-pressure environment the pump needs to operate efficiently.
