This injector sleeve tool set serves as a practical companion for servicing Caterpillar 3406E, C-15, and C-16 truck engines. The kit is built from heavy-duty steel that undergoes precise machining to achieve dependable hardness and a natural resistance to corrosion. Inside the package you receive a 9U-7227 injector height tool, a J-38587-A engine barring socket, a 9U6877 thrust bearing, a 9U7258 driver cap, a 221-9778 puller stud, a 4K-0367 nut, a 5P-8247 hard washer, and a 128-7889 puller bridge. Together these components allow you to install and remove injector sleeves without removing the cylinder head from the block, saving hours of labor on the shop floor or in the home garage. The barring socket makes it easy to rotate the engine during height adjustments, and the height tool provides a straightforward way to dial in the correct injector position. The assembled set measures approximately 10.2 inches long by 4.1 inches wide by 3.1 inches high and weighs just over seven pounds, so it stores neatly in a toolbox drawer when not in use.
