STANDARD PROCEDURE—PISTON FITTING (1) To correctly select the proper size piston, a cyl- inder bore gauge, capable of reading in 0.003 mm ( (2) Measure the inside diameter of the cylinder bore at a point 49.5 mm (1-15/16 inches) below top of (3) The coated pistons will be serviced with the piston pin and connecting rod pre-assembled. The (4) The coating material is applied to the piston after the final piston machining process. Measuring (5) Piston installation into the cylinder bore requires slightly more pressure than that required PISTON SIZE CHART CYLINDER BORE SIZE PISTON LETTER SIZE 98.438 - 98.448 mm (3.8755 - 3.8759 in.)
