The Special Service Tool Spacer introduces a defined gap that allows service tools to apply force while keeping adjoining interfaces separated during positioning steps. This spacing supports linear movement of the cartridge as it is guided into its intended position, allowing alignment adjustments to occur gradually. Maintaining separation during force transfer, the spacer helps manage contact timing between the cartridge and mating interfaces. This function supports predictable movement during installation, allowing the cartridge to advance without interference while tools maintain engagement.Attributes:• Supports guided linear movement during positioning.• Enables smooth continuation of installation actions.• Maintains functional separation during tool operation.Applications: The Special Service Tool Spacer is used during installation of the minor bogie cartridges to maintain controlled spacing and alignment while service tools guide positioning actions.
