A thrust washer is placed against the damper and you tighten the nut. The Kent Moore tool actually has a hole right through the shaft allowing you to tighten up the bolt. (Image/Wayne Scraba) To install the damper, the small threaded end of the tool goes into the crank. The other is an equally ancient Moroso example. (Image/Wayne Scraba) To install a damper, you need a tool such as either of these (again, both well used examples from my tool box): The double ended job is a vintage GM Kent Moore example. This tightening action forces the damper off the crank. To operate it you simply turn the huge-X-large nut on the equally large screw. (Image/Wayne Scraba) The plate is positioned over the face of the damper and bolted to the threaded crank pulley holes. As you can see, itвЂ™s a dirt simple device with only two parts. This is an old, well-used GM Kent Moore damper removal tool from my tool box. Check out the accompanying photos for more details. YouвЂ™ll find what was once a royal pain and a seemingly impossible task (or at least extremely frustrating) turns out to be easy. Just be sure to check the threads so that they donвЂ™t bottom out and be sure to use anti-seize on the crank snout when installing them. With any of these tools, harmonic damper removal and installation is a piece of cake. With this setup, youвЂ™ll have to purchase an additional dedicated installation stud. The Chevy LS engine family is in that group and so are new Gen III HEMI engines and Duramax diesels.ДЄTI makes a tool (ATI-918999) specially designed for these types of engines. Again, like magic, the damper should slide onto the crankshaft. The idea here is to tighten the nut with hand tools. The bearing and/or the washer are backed by a large nut. Others use a large washer to act as a thrust surface. Some of the tools on a large bearing to help distribute the load. Next apply a coating of anti-seize to the crank snout, install the key, and slide the damper over the snout. ThereвЂ™s a huge amount of force applied by the big nut on the tool during the installation process. If the tool bottoms out in the crank, thereвЂ™s a good chance the thread will snap during the tightening process. In any case, the idea with the installation tool is to thread it into the crankshaft snout.ДЄ word of caution: There are situations where the small snout threads on the tool are too long or the crank snout isnвЂ™t drilled and threaded sufficiently deep.

Many different versions are available for different-sized crank snout threads. I also have an older Moroso part number 61741 installation tool, and it has a dedicated 1/2-20 thread for the crank snout. Some tools like my old Kent Moore installation tool are double ended - one size fits a small block Chevy application (7/16-20) and another fits a big block Chevy application (1/2-20). Harmonic balancer installation tools typically have an end sized to fit the threads in the crankshaft snout. Installation is equally easy with the right tool. ItвЂ™s simple and effective, and creates no damage to the damper or crankshaft. The magic of threads goes to work, and the damper eases off the end of the crank. Using a 1-1/8-inch socket or wrench (socket size depends upon the tool - IвЂ™m referencing my old Kent Moore puller here), you simply tighten the screw. The puller usually includes a large diameter, fine-thread screw that runs through the center of the plate. Typically, the plate attaches to the same bolt pattern as the crank pulley. A really good example is Summit RacingвЂ™s removal/install tool, (SUM-G1025).ДЄ good damper removal tool is simple to use and extremely effective.ДЇor the most part, you simply bolt a plate to the face of the damper.

I have a couple of examples including several vintage GM Kent Moore service jobs in my tool box. The good news, and the real solution, is to use the appropriate tools. ThereвЂ™s a really good chance you can destroy the threads in the crank snout doing that. You can damage the damper easily.Дitto if you use a bolt to try and pull it on by way of the crank threads.

How about installing one? A block of wood and the biggest hammer in your tool box, or even a dedicated pulley driver arenвЂ™t the answers either. In fact, most aftermarket harmonic damper manufacturers explicitly note that the use of a three-jaw puller is forbidden with their respective products. You might get away with yanking one off with a common three-jaw puller, but you can bet your boots the damper will be damaged, if not ruined. Harmonic dampers are typically press-fit and next-to-impossible to properly remove and install without the right tools.
