Втулка топливного насоса высокого давления Caterpillar 3932923

The Fuel Injection Pump Sleeve fits over the pump shaft to maintain surface contact with seals and prevent direct wear on the shaft itself. It serves as a protective interface between rotating parts and static components, helping reduce scoring, oil seepage, and vibration. The sleeve supports consistent shaft motion and helps extend the service life of surrounding seals and housings during injection cycles.Attributes:• Helps maintain smooth shaft-to-seal interface during rotation.• Built for accurate fitment around the fuel pump shaft.• Reduces shaft wear from seal friction and debris exposure.Applications: The Fuel Injection Pump Sleeve, installed around the shaft of a fuel injection pump, helps to protect contact areas from leak paths, aiding pressure and reducing component wear over time.
