Assemble piston rings

explanation about assembling piston rings
This blog gives an explanation about the two most frequently used types of piston rings for a (Honda) four-stroke moped and small motorcycle.
Do you still have questions about assembling piston rings on a (Honda) four-stroke moped or small displacement motorcycle after reading this blog? Please comment on the bottom of this page!
3-piece type
A 3-piece set of piston rings consist of different types of rings, namely:

First compression ring (upper). Chrome or light-coloured on the edge of the ring.
second compression ring (middle) Dark or black colour.
Oil ring.
Near the opening of the piston rings is the so called "gap". Near the gap of the piston ring there is always a small marking. Assemble the piston ring always with this marking up, with other words, towards the top of the piston.
Always put the gap of the piston rings in opposite direction of each other!
5-piece type
A 5-piece set of piston rings consist of different types of rings, namely:

First compression ring (upper). Chrome or light-coloured on the edge of the ring.
second compression ring (middle) Dark or black colour.
3-piece oil ring
Near the opening of the piston rings is the so called "gap". Near the gap of the piston ring there is always a small marking. Assemble the piston ring always with this marking up, with other words, towards the top of the piston.
Put the gap of the compression piston rings always in opposite direction of each other! To assemble the oil ring the right way, put the copper coloured ring in the ring groove and subsequently put the two thin rings under and upper the copper coloured one. Put the gap of the thin rings also in the opposite direction of each other.
Goodluck!

De drie-delige olieschraapveer is een nieuwere techniek, welke in de regel inderdaad wat beter afsluit.

De schraapveer die uit 3 veren bestaat Werkt die ook beter? Mvg jasper
Dag Rob, Op de dunnen veertjes van een 3-delige olieschraapveer staan meestal inderdaad geen lettertjes. Die kun je er dus zo in zetten... Groeten Coos!
