The Spacer Sleeve Assembly supports accurate injector height measurement by maintaining consistent gauge alignment during the checking process. It prevents incorrect injector height settings that can affect injector performance. It supports the injector height gauge by keeping it properly aligned against the injector spring. It allows measurements to remain stable and repeatable during adjustment.Attributes:• Maintain proper injector height during measurement activities.• Supports stable alignment of the injector height gauge.• Reduces measurement errors caused by angled gauge positioning.Applications: The Spacer Sleeve Assembly is applied during injector height measurement procedures in fuel system servicing areas. The assembly supports injector height gauge alignment against the injector spring to maintain accurate measurement results.
