Replacement piston for the blown 41 mm cylinder with 12 mm piston pin and 2 pcs. 1.5 mm rectangular piston rings with flank lock (FS) suitable for Puch X30 Velux mopeds / mopeds.
The detailed dimensions of the piston according to the technical drawing can be found in the details. You can also find out more about the piston rings used, their stems and locking types on the legend in the pictures.
This special piston has a molybdenum coating. In combination with oil, this results in technologically advanced wear protection with outstanding sliding properties. The piston is more durable and provides minimal additional performance compared to an original piston from Meteor.
The Meteor piston manufactured for swiing is characterized by its high-quality and precise fit.
Attention: We recommend a running clearance of 0.06-0.07 mm, the cylinder should therefore be honed to 41.01 mm.
The piston kit contains piston pins, piston clips and piston rings.
You will find the corresponding assembly tool, piston pin locks and, if necessary, the corresponding cylinder in the accessories section.
