top and second piston rings (750) which is top ring?
« on: December 04, 2017, 12:26:40 PM »
The oil ring is obvious, but which is the top ring and which is the 2nd? Installing new RIK rings.
there's a pic here somewhere, but I cant find it. the man. mark is on top of both rings.
there has to be a difference between the two, yes?

Pewe  is right. The top ring is usually chrome and of a lighter color. Second ring is of a darker color, possible just cast.  Man. marks are installed in the up position.  I'm sure you will get it.  Chuter
