The Hub Bearing Spacer Set maintains the correct position of the duo cone seal during undercarriage removal procedures. It helps keep the seal aligned between the drive wheel hub and reaction arm hub during maintenance activities. It allows controlled handling of the seal when the hub assembly is separated. Proper positioning reduces the risk of seal displacement during service work.Attributes:• Prevents movement of the seal during hub separation procedures.• Reduce bearing lubricant leakage caused by seal misalignment.• Positioning helps maintain bearing lubrication efficiency.Applications: The Hub Bearing Spacer Set is positioned between the drive wheel hub and the reaction arm hub during undercarriage maintenance. It maintains the duo cone seal alignment while the hub assembly is separated, helping prevent lubricant leakage and seal damage.
