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

The pictures show the basic procedure with my old, broken piston/cylinder.
