Mechanics working on Detroit Diesel engines, this cylinder liner puller tool will save you so much time and frustration! Specifically designed for 60 series engines including the 12.7L EGR, 14L models, and the newer DD13, DD15, and DD16 engines. It's fully compatible with the OTC 5875 tool, so if you're familiar with that one, you'll feel right at home. The tool weighs about 30.8 pounds and is built like a tank from durable materials that can handle heavy-duty use. The three-step operation is straightforward: insert the tool into the cylinder, tighten the expansion nut to grip the liner securely, then tighten the bridge nut to release the liner from the engine block. The convenient handle makes lifting the liner out much easier than wrestling with it manually. This is one of those specialized tools that pays for itself the first time you use it, especially if you're doing regular maintenance or rebuilds on these engines. The quality construction means it'll last through many jobs without wearing out. Whether you're working in a shop or doing field repairs, having the right tool for cylinder liner removal makes what could be a difficult job so much more manageable. Definitely a must-have for anyone serious about working on Detroit Diesel power plants!
