The Wacker Neuson 5100012625 is a genuine OEM Oil Level Indicator designed for the RD18 series tandem rollers, including RD18-80 and RD18-100 variants. As an authentic Wacker Neuson part, the 5100012625 is manufactured to the same specification as the original component, ensuring a direct, trouble-free installation. This indicator covers a wide range of RD18-80 and RD18-100 configurations — including C, SE, US, and.3 sub-variants — making it the correct choice for most RD18 tandem roller builds.
Key Features
- Genuine OEM Transparency and Accuracy — Manufactured to original specification, delivering accurate oil level readings essential for protecting the roller's drivetrain and hydraulic systems from low-oil damage.
- Direct-Fit Installation — Engineered as an exact replacement for the original indicator, mounting to the same port and seating to the same tolerances as the factory-installed part.
- Broad RD18 Series Coverage — Compatible across RD18-80 and RD18-100 tandem rollers, including C, SE, US, and .3 model variants, consolidating fitment across the full RD18 family.
- Protects Critical Machine Systems — A functioning oil level indicator allows operators to catch dangerously low oil conditions before they cause compressor, drum drive, or hydraulic damage — a failed or missing indicator removes that safeguard entirely.
- Verified OEM Part Number — Sourced directly from Wacker Neuson, so the part number 5100012625 matches the OEM bill of materials for supported RD18 configurations.
An oil level indicator gives operators a fast, visible check of fluid levels within key machine systems without opening service ports or removing components. On a tandem roller like the RD18, maintaining correct oil levels in the drum drive, hydraulic circuit, or engine is critical to sustained compaction performance — low oil in any of these systems can accelerate wear or cause sudden component failure. When the indicator becomes cloudy, cracked, or begins leaking, replacing it promptly restores the operator's ability to monitor fluid status and keep the machine running safely between service intervals.
