Rotax 582 Blue head (part 2) component measurements

Now that the engine is dismantled, the components must be accurately inspected and measured. This is performed to assess the current condition and determine if the part may be reused. A detailed visual inspection and measurement of the rotary shaft is performed. A piston and matching cylinder are then visually inspected and both are accurately measured to determine there actual size. These dimensions are then used to determine the actual piston to cylinder clearance. During the examination of the other piston a serious fault in the cooling system is discovered.
