Видео о продукте

1. Основные характеристики и преимущества

• OEM cross references 585-8758 & 142922743 – Direct replacement common rail pressure sensor for Caterpillar C7.1 (Perkins) engines, used in CAT336 and other C7.1-powered excavators.

• Critical fuel system component – Installed on the common rail, this sensor measures instantaneous fuel pressure inside the rail and sends a voltage signal to the ECM. The ECM uses this data to precisely control fuel injection quantity, injection timing, and rail pressure regulation for optimal combustion.

• Restores engine power and efficiency – A failing rail pressure sensor causes low power, rough idling, black smoke, poor fuel economy, or engine derate. Replacing it restores proper fuel delivery and combustion.

• High-precision sensing element – Built with robust piezoresistive micro strain gauge technology, delivering accurate pressure readings across the entire operating range.

• Plug-and-play installation – 3-pin connector with 18mm thread diameter, manufactured to OEM specifications for direct bolt-on replacement. No programming or calibration required – the ECM automatically reads the sensor’s signal.

• High-pressure rating – Designed to withstand common rail pressures up to 1,600–1,800 bar (23,200–26,000 psi), matching genuine OE specifications.

• Широкая совместимость – Fits CAT336, 336D2, 336GC, 330D, 340D2, 349D2, as well as many other C7.1-powered excavators, wheel loaders, backhoes and telehandlers.

• Быстрая доставка – 6–8 working days lead time from our Guangzhou warehouse, shipped in protective packaging.

3. Применение

• Ремонтно-механические мастерские – The most common sensor replacement on high-hour C7.1 engines. Keeping one in stock allows same-day turnaround for customers experiencing power loss or derate issues.

• Горнодобывающая и карьерная промышленность – Continuous high-load operation accelerates sensor wear; proactive replacement prevents unexpected engine derate and costly downtime in remote mine sites where service support is limited.

• Тяжелое строительство и земляные работы – CAT336 excavators working on highway projects, dam construction, and large-scale earthmoving need consistent engine power. A failing rail pressure sensor causes intermittent power loss that can halt production.

• Техническое обслуживание парка арендованного оборудования – Renters expect reliable performance. Proactive sensor replacement based on hour intervals reduces breakdowns and protects your fleet’s reputation.

• Энергетические проекты – C7.1 engines are also used in generators and pumps. Rail pressure sensor failure on a generator set can cause complete shutdown or unstable power output.
