The CTA ToolsISX Rear Camshaft Seal and Sleeve Remover and Installer Set, No. 3895, is designed to easily install and remove crankshaft rear main seals and wear sleeves on a wide range of Cummins engines, including ISX, QSX, ISX15, and ISX12 models. Made from high-standard carbon steel. The tool uses the flywheel CAD screws and positions the rear seal properly when pulled flush to the flywheel housing. It also uses self-tapping screws to attach the tool to the seal. The forcing screw is then able to pull the tool and remove the seal.
