Cometic 2017 Harley-Davidson Milwaukee 8 Torque 4.075in Bore Plate Set

This Cometic torque plate set is specifically made for the 2017 Harley-Davidson Milwaukee 8 engine, featuring a 4.075-inch bore size. These plates are crucial for ensuring the cylinders remain perfectly round during the critical torque plate honing process. Without them, the heat and stress of torquing the engine down can distort the cylinder bores, leading to potential issues like poor ring seal and oil consumption.

Cometic uses a well-built, solid construction for these torque plates, designed to withstand the forces involved in accurately machining the cylinders. The precise 4.075-inch bore diameter ensures that the honing process matches the intended final bore size for your Milwaukee 8 build. This attention to detail is what helps achieve a proper seal between the piston rings and cylinder walls, which is vital for engine performance and longevity.

When rebuilding or modifying your Milwaukee 8 engine, using the correct torque plates like these from Cometic is a key step for a professional and reliable outcome. They help maintain the integrity of your cylinder bores throughout the assembly and initial break-in process.
