MINI 60 CC ENGINES: GREAT TRUTHS (AND FALSE MYTHS!) ON THEIR PROPER MAINTENANCE AND MANAGEMENT ON THE TRACK - PART 2 OF 3

For accurate diagnosis and effective resolution of mechanical issues, specialized precision tools are essential, such as micrometers, bore gauges, and hundredth calipers, which enable precise measurement of component tolerances and wear. Specifically, it is crucial to have instruments capable of measuring the nominal diameters of:

• 42,00 mm, for cylinders/pistons;
• 24,00 mm, for connecting rods;
• 20,00 mm, for main bearings

These tools are essential for assessing the condition of components such as the cylinder, piston, and bearings, enabling timely intervention before irreparable damage occurs. For example, measuring the piston-cylinder tolerances is crucial to prevent seizure, while checking the contact surfaces in bearings helps avoid harmful vibrations or excessive play.
