Guys,
I need to replace a piston ring on one of my A65 pistons.
My pistons are the Airmotive No 4557.
These pistons have 4 rings not the normal 3.
The top 2 look the same type - flat faced.
The third one has a beveled lower edge.
And the lower one has a step and I assume is a standard oil control ring.

I need to replace ring number 3 - the one with the beveled lower edge.

Since the Continental manual only shows 3 rings on the piston, I am not sure what type of ring this is and what the P/n would be?

Please help.

Joe
