Refitting the cylinder/piston assembly
If a new cylinder/piston assembly is to be fitted, make sure that the piston and cylinder are of the same size class.
The letter indicating the cylinder size class is stamped on the cylinder-head mating face; the piston size class letter is stamped
on the crown in between the two recesses.
If the pistons have been separated from their cylinders, before reassembling these components, position the piston ring
gaps at 120° from one another (the markings must always face the piston crown).
Use a universal tool to carefully insert the piston into the cylinder (first lubricate the inside of the cylinder with engine oil).
Position the cylinder with the smallest valve pockets facing the exhaust port.
Remove any deposits and degrease the contact surfaces of the crankcase and the cylinders.
Check that the dowel (1) is installed on the crankcase.
