Quick explanation with ZERO guarantee:

• Insert your piston ring(s) at their proper position.
• Add a bit of oil to the contact surface of cylinder + piston.
• Put the clamp over your piston ring(s) thightning it using the clamp tabs
• Keep the clamp as low as you can so you can actually insert the piston into the cylinder.
• Insert the piston into the cylinder, press down the clamp using the cylinder until all piston-rings are inside the cylinder
• remove the clamp, and finish reassembly :D
