Гайка топливного насоса высокого давления Caterpillar 5I5146

The Fuel Injection Pump Nut manages retention and load distribution at a threaded connection within the fuel injection pump control interface. When tightened, the nut applies axial force while the integrated washer surface spreads clamping load across the contact area, limiting localized movement at the joint. This combined action helps the connected components remain held at the selected setting during operation cycles where motion input and load variation occur.Attributes:• Distributes clamping load across the contact surface.• Supports a fixed relationship between connected components.• Maintains contact pressure at the joint interface.Applications: The Fuel Injection Pump Nut is used on the fuel injection pump to retain threaded connections and maintain control settings during operation and service activities.
