The Wacker Neuson 5100012211 is a genuine OEM Hydraulic Oil Tank designed for the RD24-100, RD27-120, and RD28-120 series ride-on articulated tandem rollers. As a direct OEM replacement, this tank is manufactured to the same standards as the original unit, ensuring correct capacity, port placement, and mounting configuration for a straightforward swap. This part covers an extensive range of configurations across the RD24, RD27, and RD28 families — including standard, combination, and open-ROPS variants — making it one of the most broadly compatible hydraulic components in the RD series lineup. Confirm your machine's model and serial number against the fitment list before ordering to ensure an accurate match.
Key Features
- Genuine OEM Construction — Manufactured to the exact capacity and material specifications of the original tank, ensuring the hydraulic system maintains correct fluid volume and operating pressure across the full duty cycle.
- Direct-Fit Replacement — Port locations, mounting brackets, and tank geometry match the original installation points on RD24-100, RD27-120, and RD28-120 tandem rollers, allowing for a clean, straightforward replacement.
- Broad RD-Series Compatibility — Fits multiple configurations across the RD24-100, RD27-120, and RD28-120 families, including standard, combination drum, and open-ROPS variants, as well as US-market models.
- Hydraulic System Integrity — A properly functioning hydraulic oil tank maintains the fluid supply that powers drum drive, steering, and vibration systems; a cracked, leaking, or undersized tank can cause erratic roller behavior and accelerated pump wear.
- Verified Part Number — OEM part number 5100012211 is the authoritative reference for sourcing this component; cross-check against your machine's serial number and parts manual to confirm the correct application.
The hydraulic oil tank serves as the reservoir for the roller's hydraulic fluid, supplying the pump with a consistent, clean fluid source that powers the drum drive motors, vibratory system, and articulated steering circuit. Without adequate fluid volume and a sealed, structurally sound tank, pressure drops and aeration can occur, leading to sluggish or unresponsive machine behavior and increased wear on pumps and motors. A damaged or leaking tank should be replaced promptly to protect the entire hydraulic circuit and maintain consistent compaction output on asphalt and soil surfaces.
