The tool applies controlled force through a forcing screw to ensure uniform seating from cylinder to cylinder. The tool removes the need for sleeve reaming after installation, saving service time. Consistent seating force also prevents injector clamp bolt load loss during engine operation.Attributes:• Helps stop combustion gas leakage at the injector location.• Corrects injector sleeves that are out of round during service.• Ensures consistent injector seating from cylinder to cylinder.Applications: An Injector Seating Wear Button is used at the injector sleeve location during engine service to apply a controlled force that seats injector lands evenly, corrects sleeve shape, and prevents combustion gas leakage.
