Measuring cylinder bore is a critical step in the engine rebuilding process. It ensures that the new piston and rings will fit properly and that the engine will run smoothly. There are a few different ways to measure cylinder bore, but the most accurate method is to use a dial bore gauge.
A dial bore gauge is a precision instrument that measures the diameter of a hole. To use a dial bore gauge, first insert the gauge into the cylinder bore. Then, rotate the gauge until the dial indicator reads zero. Next, slowly withdraw the gauge from the cylinder bore while watching the dial indicator. The dial indicator will read the diameter of the cylinder bore at its widest point.
