Wiseco 1166 piston rings orientation K1171 for future ref.

[Al]

Did a search on site for piston rings, piston and rings, wiseco piston rings etc etc etc. Searched web and wiseco site. Looked at oldkawmans posts and could not find reference to piston rings; first and second identification.
For the record and future searches, Ray Debben has confirmed that the top (compression ring) is the orangy/red ring with the white outer coating (working face) and the second ring is the dull matt grey ring.
In the contained instructions it shows a small black and white diagram of the end profile of the two different rings but without an electron microscope it was not obvious to me which is which.

'N' orientation remains the same as before (ie uppermost) but reading through the instructions there is no reference to the positioning of these rings and they mic up the same (1mm each) and therefore can be transposed in the ring grooves.
I am guessing that this is an omission by Wiseco or maybe i'm being thick but i believe that they have revised some of their ring kits in recent times.

hope this might help just had a look at a 1075 wiseco piston, and the top ring is slightly thinner on the set of piston that i have

Whizzy-Co have different ring set ups...... and each kit needs to be checked for individual specific requirements before installation.
