The Wacker Neuson 5100023676 is a genuine OEM Engine Oil Pressure Switch designed for the RC50 and RC70 single-drum soil compactor series and the RD40-130 and RD45-140 tandem roller series. As a direct OEM replacement, this switch is built to the exact specifications required by Wacker Neuson to ensure proper monitoring and protection of the engine lubrication system. Fitment covers a wide range of configurations across both the RC and RD families, including DPF, CAB, ROPS, open-ROPS, padfoot, and smooth-drum variants. Verify your model number against the fitment list before ordering to confirm compatibility with part number 5100023676.
Key Features
- Genuine OEM Calibration: — Manufactured to Wacker Neuson's exact pressure threshold specification, ensuring the switch triggers and cuts out at the correct oil pressure values for engine protection.
- Drop-In Electrical Connector Match: — Designed to connect directly to the existing engine wiring harness on compatible RC and RD series machines with no adapter or re-pinning required.
- Broad RC and RD Series Coverage: — Fits RC50, RC50P, RC70, RC70P, RC70VO single-drum soil compactors and RD40-130, RD40-130C, RD40-130O, RD45-140, RD45-140C, RD45-140O tandem rollers across standard, DPF, CAB, and ROPS configurations.
- Engine Protection Integrity: — A correctly functioning oil pressure switch is the engine's first line of defense against low-pressure conditions; a failed switch can mask a developing lubrication fault or cause nuisance shutdowns that stall compaction operations.
- Fuel System Safety Compliance: — On machines equipped with DPF or cab configurations, the oil pressure switch is integrated into the engine protection circuit; using an OEM-spec switch maintains the integrity of that safety interlock.
The engine oil pressure switch monitors the oil pressure within the engine's lubrication circuit and sends a signal to the machine's control system when pressure drops below a safe operating threshold. When functioning correctly, it triggers a warning or automatic shutdown before low oil pressure can cause internal engine damage — a critical protection feature on high-load compaction equipment like soil compactors and tandem rollers. When the switch fails, operators may experience false low-pressure warnings, failure to start, or — more dangerously — the loss of any warning at all if the circuit goes open, leaving the engine unprotected against a genuine pressure loss.
