Big Twin Evolution tappet blocks do not have counter-bored bolt holes; therefore, when a tappet block is removed (or even just loosened) it should be reinstalled using an alignment tool to ensure that the lifters track properly on the camshaft. This tool makes the process quick and easy, helping ensure the durability of your installation. It also aligns the Twin Cam oil pump to the cam support plate; on Twin Cam engines two tools are required for correct alignment. 🔧🛠️
Use this alignment tool during reassembly to reduce wear, prevent misalignment, and save time on final adjustments. Suitable for shop or home use, it speeds up accurate positioning of tappet blocks and oil pump components for reliable results.
