The Wacker Neuson 5100024947 is a genuine OEM Compensator Tank designed for the RD40-130 and RD45-140 series tandem rollers. As a factory-sourced component, it is manufactured to the exact specifications required for proper hydraulic system function in these machines. This part is confirmed to fit the RD40-130, RD40-130C, RD40-130O, RD45-140, RD45-140C, and RD45-140O tandem roller models. Ordering by part number 5100024947 ensures you receive the correct tank for a direct, hassle-free installation.
Key Features
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this compensator tank meets the exact material and dimensional requirements for hydraulic compatibility in the RD40 and RD45 roller families.
- Direct-Fit Replacement — Engineered to match the original mounting points and hydraulic connections on the RD40-130 and RD45-140 series, so installation follows the standard service procedure without rework.
- Broad RD-Series Coverage — Fits six tandem roller configurations: RD40-130, RD40-130C, RD40-130O, RD45-140, RD45-140C, and RD45-140O.
- Hydraulic System Integrity — A properly functioning compensator tank maintains correct fluid volume and pressure balance in the hydraulic circuit, keeping drum drive and steering response consistent during compaction passes.
- Verified Part Number — Cross-reference part number 5100024947 against your machine's serial number and model designation before ordering to confirm an exact match.
The compensator tank serves as a hydraulic fluid reservoir that accommodates volume changes caused by thermal expansion and contraction within the closed hydraulic circuit. On tandem rollers like the RD40-130 and RD45-140 series, maintaining correct fluid levels in this tank is essential for consistent drum drive performance and responsive directional control. A cracked, leaking, or degraded compensator tank can cause hydraulic pressure loss, erratic roller behavior, and potential damage to downstream hydraulic components if left unaddressed.
