ВТУЛКА Caterpillar 1391444

The Carburetor Body Upper Bushing provides a stable interface that allows the throttle shaft to rotate freely while maintaining alignment with the throttle bore. This bushing controls shaft motion under repeated operation, reducing mechanical friction and preventing direct metal contact with the carburetor housing. It also contributes to sealing the upper bore to minimize potential air leaks, which is required for maintaining consistent air-fuel ratio control.Attributes:• Supports throttle shaft at the upper entry point into the carburetor body.• Limits shaft vibration and prevents metal-on-metal housing contact.• Prevents air leakage by ensuring a tight seal around the shaft.Applications: The Carburetor Body Upper Bushing is positioned at the upper throttle shaft entry point in the carburetor body to support shaft alignment, reduce friction, and maintain sealing integrity during air-fuel mixture regulation.
