The Wacker Neuson Oil Pressure Sender is a genuine OEM component designed for the HI 770 XHD series indirect-fired air heaters. Sourced directly from Wacker Neuson, this sender meets the exact electrical and pressure specifications required by the HI 770 XHD platform, ensuring the machine's oil pressure monitoring system performs as intended. It is a direct-fit replacement confirmed for HI 770 XHD diesel indirect air heater configurations, including 2x12, 1x16, and 1x20 duct arrangements as well as Extra Heavy Duty variants. When it comes to a safety-critical sensing component like this, using the correct genuine OEM part is the straightforward choice.
Key Features
- Genuine OEM Sensing Accuracy — Matched to the correct pressure range and output signal for the HI 770 XHD engine circuit, so the heater's control system receives an accurate reading every time.
- Direct Plug-In Replacement — Engineered to the original connector and thread specification, allowing straightforward installation without adapters or modifications to the wiring harness.
- Broad HI 770 XHD Coverage — Fits multiple HI 770 XHD indirect air heater configurations, including 2x12, 1x16, and 1x20 duct models as well as Extra Heavy Duty variants.
- Protects the Diesel Power Unit — A functioning oil pressure sender enables the heater's safety circuit to shut down the engine before low oil pressure causes internal engine damage — a failed sender defeats that protection entirely.
- Safety-Critical Electrical Compliance — On a diesel-powered heater operating in enclosed or cold-weather work environments, an accurate oil pressure signal is essential to safe automatic shutoff function.
The oil pressure sender monitors engine oil pressure in real time and transmits an electrical signal to the heater's control or warning system. This signal triggers a low-pressure shutdown or alert if oil pressure drops below a safe operating threshold, protecting the diesel engine from damage caused by oil starvation. When the sender fails or sends an incorrect signal, the machine may either shut down unexpectedly or — more critically — fail to shut down when oil pressure is genuinely low, putting the engine at risk of serious internal damage.
