A Fan Drive Spacer creates space between the fan assembly and its mounting surface. It is a cylindrical part made of stronger material such as steel and mounted between the engine's pulley and the fan blade assembly and allows the fan to rotate freely without interfering with other engine components.Attributes:• Hardened with Rockwell Hardness C Scale value of 45, which indicates its resistance against deformation • Minimizes the transmission of vibrations and noise Applications:A Fan Drive Spacer helps maintain the proper distance and alignment between the engine and the fan assembly, allowing for efficient cooling and distributing forces evenly between them.
