Okay, the bottompart is now more or less complete and now we continue with pistons and cylinders. I always smear a little grease on both sides of the basegaskets. Take the pistons and fit the pistonpinclip on the inside of each piston (left piston r.h., right piston l.h.). Mount the pistonrings with some oil and fit each piston with their respective pin and bearing (some oil). Insert the outside pistonpinclips. When this has been done you can slip the cylinder over each piston. Just pull the piston in its top dead center, with one hand hold the piston and compress the pistonrings and the cylinder will slide over the piston easily. Really easy …..!
