The Wacker Neuson Temperature Switch is a genuine OEM Temperature Switch designed for the RD40-130, RD45-140, RD24-100 DPF, and RD28-120 DPF series tandem rollers, along with their C and O variants. As a direct OEM replacement, this switch is sourced from Wacker Neuson and built to the same specification as the original component installed at the factory. Fitment spans a broad range of RD-series tandem rollers — including standard, DPF-equipped, and variant configurations — making the correct replacement across the full lineup. Confirm your model number before ordering to ensure a direct match.
Key Features
- Genuine OEM Thermal Accuracy — Manufactured by Wacker Neuson to the same switching threshold as the original, ensuring the engine management system receives a correctly calibrated signal.
- Direct Drop-In Replacement — Matches the original connector type, thread pitch, and mounting configuration for a straightforward swap with no additional hardware needed.
- Broad RD-Series Compatibility — Fits RD40-130, RD45-140, RD24-100 DPF, and RD28-120 DPF tandem rollers, including standard, C, and O variants across multiple build series.
- Protects Against Overheating Damage — A correctly functioning temperature switch triggers the appropriate shutdown or warning response before sustained high temperatures can cause costly engine or hydraulic damage.
- Electrical Safety Compliance — As a genuine OEM electrical component, it meets the original circuit protection and switching specifications, keeping the machine's thermal protection system operating as intended.
A temperature switch monitors engine or fluid temperature and sends a signal to the machine's control system when a set threshold is reached — triggering a warning light, activating a cooling circuit, or initiating a protective shutdown. On compaction equipment like the RD-series tandem rollers, this protection is critical during sustained operation in warm conditions or under heavy load. When the temperature switch fails or reads inaccurately, the machine may run without adequate thermal protection, increasing the risk of undetected overheating and potential engine damage.
