Installation Tips for Vertex Pistons:

After disassembling the cylinder head and the cylinder, it’s necessary to measure the actual cylinder diameter (1), using a dial bore gauge. When actual bore size is known then it is time to pick the right VERTEX piston to fit your bore size, respecting the clearance suggested with the cylinder. Attention must be paid to any markings (i.e. T) on the rings surface: always position the ring with the written part on the top side.

To assemble the rings on the piston you must start from the oil ring and introducing as first the spring (2) paying attention to not place one on the top of the other the two extremities. After setting the two foils one up and the other down at direct contact with the groove, taking care that the open tips must be at 1200 from the spring open tips.

We are now ready to assemble the compression ring(s) into the piston groove(s): first of all pay attention to not crush or damage the ring during installation, every precaution should be taken not to compromise the ring integrity with the groove and to not reduce the rings retaining pressure.
