Yes, you can install a harmonic balancer without a puller holder, but it requires caution and the right tools. First, ensure the crankshaft and the balancer's mating surfaces are clean. Align the keyway on the balancer with the key on the crankshaft. Gently slide the balancer onto the crankshaft by hand as far as possible. To press the balancer further onto the crankshaft, use a harmonic balancer installation tool. This tool threads into the crankshaft and allows you to press the balancer on evenly by turning a nut or bolt. Avoid using a hammer or excessive force, as this can damage the balancer or crankshaft. If you don't have an installation tool, you can use a longer bolt with the same thread as the crankshaft bolt. Thread it into the crankshaft and use washers or a spacer to press the balancer on by tightening the bolt. Ensure the bolt is long enough to engage the crankshaft threads fully but not so long that it bottoms out. Once the balancer is seated, remove the installation tool or longer bolt and install the original crankshaft bolt. Torque it to the manufacturer's specifications to ensure the balancer is securely fastened. While it is possible to install a harmonic balancer without a puller holder, using the proper tools is recommended to avoid potential damage and ensure a secure fit.
