no springs to launch, just keep it clean. A big sheet of aluminum foil works well. There is a teeny little plastic bodied check valve that can fall out if you tip it over, but that's about it. There are 15 bolts that take a 10mm socket for that valve body, the 3 on the right side are slightly longer. Retorque evenly to 8 Nm. The band clearance should be 5.5-6.0 mm.
